Chiefs of the Six Nations explaining their wampum belts to Horatio Hale, 1871 The term "wampum" refers to beads made from purple and white mollusk shells on threads of elm bark. Species used to make wampum include the highly prized quahog clam (Mercenaria mercenaria) which produces the famous purple colored beads. For white colored beads the shells from the channeled whelk (Busycotypus canaliculatus), knobbed whelk (Busycon carica), lightning whelk (Sinistrofulgur perversum), and snow whelk (Sinistrofulgur laeostomum) are used. Wampum was primarily used to make wampum belts by the Iroquois, which Iroquois tradition claims was invented by Hiawatha to console chiefs and clan mothers who lost family members to war.

As with conchs, the knobbed whelk is used by humans as food in such dishes as salads (raw), burgers, fritters, and chowders. As is also true of conch shells, the shell of the knobbed whelk can be made into a natural bugle by cutting off the tip of the spire in order to form a mouthpiece. Historically, American Indians used the knobbed whelk as a component in wampum, the shell beads exchanged in North America for trade.

Stramonita haemastoma is a widespread gastropod that consumes bivalves, barnacles and limpets. In the Mediterranean Sea the whelk is an important predator of the bivalve Mytilaster minimus, but where the invasive Lessepsian migrant bivalve Brachidontes pharaonis is found, the whelk prefers to prey on that species over the native bivalves and barnacles.Giacoletti, A., Rinaldi, A., Mercurio, M., Mirto, S. and Sarà, G. 2016.

This species of whelk feeds on live bivalves, and are, in turn, preyed upon by several fish (cod, dogfish, etc.) and crustaceans. They may benefit from seastar feeding, by eating the extracted bivalve remains abandoned by the seastar.Himmelman, J.H. and Hamel, J.-R.

In the dog whelk, the growth of a penis in imposex females gradually blocks the oviduct, although ovule production continues. An imposex female dog whelk passes through several stages of penis growth before it becomes unable to maintain a constant production of ovules. Later stages of imposex lead to sterility and the premature death of the females of reproductive age, which can adversely affect the entire population.

Kellet's whelk has been observed feeding together at the same time with the Giant sea star Pisaster giganteus on common food items and thus these two species are trophically interrelated. Pisaster giganteus also preys on Kelletia kelletii more often than any other motile gastropod, and yet the whelks do not appear to be eaten in proportion to their abundance or accessibility in studied localitions. The sea star appears to be a major predator of the whelk, even though Kelletia kelletii makes up less than 10% of the diet of the sea star. The whelk does not display an avoidance response in the presence of Pisaster giganteus.

The species is edible. Historically, American Indians used the channeled whelk as a component in wampum, the shell beads exchanged in the North American fur trade.
|
|
The white beads are made from the inner spiral of the channeled whelk shell. Wampum beads are typically tubular in shape, often a quarter of an inch long and an eighth of an inch wide. One 17th-century Seneca wampum belt featured beads almost 2.5 inches (65 mm) long. Women artisans traditionally made wampum beads by rounding small pieces of whelk shells, then piercing them with a hole before stringing them.

Some shellfish, such as whelk, contain arsenic. A sample of whelk was found to have a total content of arsenic at of which 1% is inorganic arsenic. Shellfish caught in Alaska can lead to paralytic shellfish poisoning (PSP). PSP is caused by toxins released by dinoflagellate, a type of algae, which are extremely poisonous (1000 times more potent than cyanide) and can lead to death by paralyzing the breathing muscles.

Researchers have found a change in the sex ratios of affected populations with fewer males than females being present with the males being consistently smaller than the females. The common starfish produces a saponin-like substance designed to repel predators, which causes a reaction in the common whelk (Buccinum undatum), a common prey species. At dilute concentrations it caused the whelk to take evasive action and at higher concentrations it produced a series of convulsions.

Certain carnivorous gastropod snails such as whelks (Buccinidae) and murex snails (Muricidae) feed on bivalves by boring into their shells, although many Busyconine whelks (e.g., Busycon carica, Sinistrofulgur sinistrum) are "chipping-style" predators. The dog whelk (Nucella lamellosa) drills a hole with its radula assisted by a shell-dissolving secretion. The dog whelk then inserts its extendible proboscis and sucks out the body contents of the victim, which is typically a blue mussel.

This whelk is a predator, feeding largely on mussels and barnacles. The radula is used to scrape through the shell of the prey and the soft tissue is extracted. The whelk is itself eaten by crabs such as the red rock crab Cancer productus and the seastar Pisaster ochraceus. In the presence of the crabs, there is a tendency for the whelk's shell to grow thicker and be more robust, and thus less easy for the crab to crush.

One common substitution is the lightning whelk (Sinistrofulgur perversum, previously named Busycon perversum) from the Atlantic coast of North America. The real Shank has 3 to 7 ridges or plaits on its columella, whereas whelk shells do not have such plaits. The so-called "flower-bud opening test", and the "rice pulling test" (Valampuri said to rise up through a rice heap) are non scientific. The best authenticity test is to take an X-ray image of the Valampuri.

Several different species of large whelks in the family Buccinidae on sale at a fish market in Japan. Miller's Point near Cape Town. Whelk (also known as scungilli) is a common name that is applied to various kinds of sea snail. Although a number of whelks are relatively large and are in the family Buccinidae (the true whelks), the word whelk is also applied to some other marine gastropod species within several families of sea snails that are not very closely related.
|
|
It is known that the abundance of prey, the lack of competition from other gastropod species, as well as the absence of direct predators of R. venosa may be some of the factors that contributed to the successful establishment of new populations of this sea snail outside its native range. The thick strong shell of the rapa whelk is arguably its strongest advantage over native whelks, because rapas can easily prey on local whelks, whereas local whelks are unable to successfully attack rapas. The thick shell also means that predators such as sea turtles are unable to feed on the invasive species, and can only feed on local whelk populations. It is suggested that once the rapa whelk reaches adulthood, it exists unchecked in the local population, and can consume and reproduce freely.
|
|
Wave action tends to confine the dog whelk to more sheltered shores, however, this can be counteracted, both by adaptations to tolerate it such as the shell and muscular foot, and by the avoidance of direct exposure to wave action afforded by making use of sheltered microhabitats in rocky crevices. The preferred substrate material of the dog whelk is solid rock and not sand, which adds to its problems at lower levels on the shore where weathering is likely to have reduced the stability of the seabed. Water loss by evaporation has to be tolerated (by means of the operculum which holds water in and prevents its escape as vapour), or avoided (by moving into water or a shaded area). The peak in dog whelk population density is approximately coincidental with the mid-tidal zone.

Species selected include the lightning whelk (Sinistrofulgur sp.), the knobbed whelk (Busycon carica), the giant triton (Monoplex parthenopeus), the moon snail (Neverita duplicata) and the Florida rocksnail (Stramonita haemastoma). The sea anemone, Calliactis tricolor, is often found attached to the shell that is occupied by Clibanarius vittatus. This seems to be a mutualistic arrangement in which the crab benefits from the fact that potential predators are deterred by the anemone's stinging cells while the anemone gains a greater access to food as the crab moves around.

The hooded oyster is common on the east coast of Africa, where it cements itself to rocks or to the branches and roots of mangroves. It sometimes even grows on the shell of a large gastropod mollusc, the mangrove whelk (Terebralia palustris), which grazes beneath the mangrove canopy. In Australia, another gastropod, the black oyster borer or mulberry whelk (Tenguella marginalba, previously Morula marginalba) feeds on the oyster by drilling a hole through its shell. It then inserts its radula and chews up the body before sucking out the pieces.

Engraved conch shell cup from Spiro Mounds In historic accounts from the 16th and 17th century, the black drink is usually imbibed in rituals using a cup made of marine shell. Three main species of marine shells have been identified as being used as cups for the black drink, lightning whelk, emperor helmet, and the horse conch. The most common was the lightning whelk, which has a left-handed or sinistral spiral. The left-handed spiral may have held religious significance because of its association with dance and ritual.

|
Tidal pools and comparable microhabitats extend the vertical range of organisms such as the dog whelk as they provide a more constant environment, but they are prone to increased salinity because evaporation concentrates dissolved substances. This can create toxic conditions for many species. The dog whelk can only survive out of water for a limited period, as it will gradually become desiccated and die if emersed for too long. Metabolic processes within cells take place in solution, and a decrease in water content makes it impossible for the organism to function properly.
|
|
Predators of the dog whelk include various species of crabs and birds. Protection against predation from crabs which attempt to pull the soft body out through the shell aperture can be afforded by growing teeth around the edge of the aperture. Many predators cannot smash the strong shell of an adult dog whelk, but juveniles are vulnerable to attack from many predatory species. Eider ducks and various other birds simply swallow the entire body with its shell, while oystercatchers and various crustaceans are often capable of crushing or breaking the shells.

The bryozoan Alcyonidium nodosum protects the whelk Burnupena papyracea against predation by the powerful and voracious rock lobster Jasus lalandii. While whelk shells encrusted by the bryozoans are stronger than those without this reinforcement, chemical defenses produced by the bryozoans are probably the more significant deterrent. Mauritanian bryolith formed by circumrotatory growth of the bryozoan species Acanthodesia commensale In the Banc d'Arguin offshore Mauritania the species Acanthodesia commensale, which is generally growing attached to gravel and hard-substrate, has formed a non-obligate symbiotic relationship with hermit crabs of the species Pseudopagurus cf. granulimanus resulting in egg-size structures known as bryoliths.

Mytilaster minimus is distributed throughout the Mediterranean Sea and is also found off Gran Canaria and Tenerife in the Canary Islands It forms colonies on hard substrates in coastal waters and in brackish water such as coastal lagoons. This species can colonise rather oligotrophic areas but in more eutrophic regions the larger Mediterranean edible mussel Mytilus galloprovincialis can be found among and, in places displace M. minimus. The whelk Stramonita haemastoma is an important predator of M. minimus but where the invasive Lesspesian migrant Brachidontes pharaonis is found, the whelk prefers to prey on that species over the native bivalves and barnacles.

Quahog and whelk wampum A representation of the original Two Row Wampum treaty belt Wampum Georgina Ontario Wampum is a traditional shell bead of the Eastern Woodlands tribes of Native Americans. It includes white shell beads hand fashioned from the North Atlantic channeled whelk shell and white and purple beads made from the quahog or Western North Atlantic hard-shelled clam. Before European contact, strings of wampum were used for storytelling, ceremonial gifts, and recording important treaties and historical events, such as the Two Row Wampum Treaty or The Hiawatha Belt. Wampum was also used by the northeastern Indian tribes as a means of exchange, strung together in lengths for convenience.

Whelk egg case Mating and egg laying occur during the spring and fall migration. Internally fertilized eggs are surrounded by a transparent mass of albumen, a gel-like material, and are laid in protective flat, rounded egg capsules joined to form a paper-like chain of egg cases, commonly called a "Mermaid's Necklace". On average each capsule contains 0-99 eggs, with most strings having 40-160 capsules. After laying their egg cases, female knobbed whelk will bury one end of the egg case into the substrate, thus providing an anchor for the developing fertilized eggs and preventing the string of egg cases from washing ashore where it would dehydrate.

Veined rapa whelks are carnivorous selective predatory gastropods whose main diet consists of a variety of other mollusk species, mainly epifaunal bivalves such as oysters (Crassostrea virginica) and mussels (Mytilus galloprovincialis, Modiolus and Geukensia), but also clams (Anadara inaequivalvis, Chamelea gallina, Tapes philippinarum, Venus verrucosa, and the northern quahog Mercenaria mercenaria). Prey are chosen by the whelk according to their species and size. Most snails feed by drilling a hole into their bivalve prey, but rapa whelks usually smother their prey by wrapping around the hinged region of the shell and feed by introducing their proboscis between the opened valves. The whelk can also secrete a thick mucus that may or may not contain biotoxins to weaken the prey.

The earliest recorded commercial landing data specific to Kellet's whelk dates back to 1979, but prior to this it may have been recorded as "miscellaneous mollusks" or "sea snails". Landings data indicate an increased intake starting in 1993 at 4590 pounds (2 metric tons), with the highest landings in 2006 being 191,177 pounds (87 metric tons). This represents an over forty-fold increase in thirteen years. Kellet's whelk landings have been reported at 24 ports from 1979 to 2008, with 80 percent of landings occurring at four ports. The majority of landings (439,828 pounds, 200 metric tons in 2008) occurred at Santa Barbara, with approximately 40 percent of the total landings reported.

Kelletia kelletii is found from Isla Asunción, Baja California, Mexico, to Monterey, CA, USA. The type locality is the "Californian coast". Studies suggest that the Kellet's whelk range expanded to Monterey Bay in the 1970s or early 1980s, possibly due to an El Niño event, and is dependent on recruits from southern California.

The small brown anemone is distributed throughout estuaries in current-free areas. They all usually found attached to cockles who with they form a commensal relationship as the anemone gets protection and the cockle becomes more camouflaged and so can hide better from predators such as the mud flat whelk (Cominella glandiformis) or sea gulls.

Strings of Busycon whelk egg capsules commonly wash ashore and desiccate, becoming brittle. These objects are sometimes called mermaid's necklaces because they resemble a large necklace strung with medallion-shaped egg pouches. Each pouch of the string contains numerous protoconchs (baby whelks), similar in appearance to adults but with fewer whorls and less sculpture.

The island is also home to an English-speaking community. Fishing is the main industry of the island with the lobster fishery being the most important, but some fishermen also harvest crab, scallops, whelk, mackerel, tuna and herring. Approximately 60 residents reside on Entry Island year around. That is down from 270 in 1980.

In the British Isles, Belgium and the Netherlands (wulk/wullok), the word is used for a number of species in the family Buccinidae, especially Buccinum undatum, an edible European and Northern Atlantic species. In the British Isles, the common name "dog whelk" is used for Nucella lapillus (family Muricidae) and for Nassarius species (family Nassariidae).
|

There were also bones from red deer and birds and an antler harpoon for catching a wide range of fish, including cod, mackerel, haddock, herring and salmon. Fine beads had been made from seashells, while ochre pigment and a particular species of dog whelk that may have been used for the extraction of purple dye suggest concern with decoration.

The common name for B. thermophilum is the endeavor vent whelk. Whelks are usually moderate to large in size, with smooth or sculptured whorls which often have a distinct shoulder. The aperture is large and a siphonal canal and horny operculum are present. They have two eyes at the base of tentacles, and a well-developed sense of smell.

The Veined rapa whelk is also highly tolerant to wide variations in salinity and oxygen concentration, a fact that may also help to explain its success as an invader of marine coastal and brackish ecosystems. In its native range Rapana venosa shows high temperature tolerance, being able to withstand temperatures varying from 4 to 27 °C (39.2 - 80.6 °F).

The pink sea star secretes digestive fluids and eats the bivalve inside its own shell. This star is opportunistic in its feeding and will eat other animals besides bivalves when available. It will eat sand dollars, snails, including Kellet's whelk, barnacles, polychaete worms, and small Dungeness crabs. It feeds on carrion, including dead fish and squid.

The widespread popularity of glass beads does not mean aboriginal bead making is dead. Perhaps the most famous Native bead is wampum, a cylindrical tube of quahog or whelk shell. Both shells produce white beads, but only parts of the quahog produce purple. These are ceremonially and politically important to a range of Northeastern Woodland tribes.

Coralline algae was often present as were the whelk, the European edible sea urchin (Echinus esculentus), the great spider crab (Hyas araneus) and the shore crab (Carcinus maenas). The main predator is the juvenile common starfish (Asterias rubens). Medium sized barnacles seem to be at greatest risk. Small specimens are ignored while large specimens seem able to withstand attack.

These form round clusters or a tower-shaped masses. Only about 10% of these eggs hatch. The larvae then feed on the rest of the eggs that have not yet hatched. The flesh of the common northern whelk, Buccinum undatum, is much appreciated by connoisseurs as a food item, but its consumption is currently somewhat in decline.

Above the sea at this location typical Southern Ocean animals are found such as several kinds of whales, albatross and petrels. Species detected include Diomedea exulans, Diomedea royal, Diomedea sanfordi, Euphausia frigida, Fregetta tropica, Limacina retroversa, Oceanites oceanicus, Oithona similis, Pachyptila belcheri, Pachyptila crassirostris, Pachyptila turtur, Pachyptila vittata, Pelagodroma marina, Phoebetria fusca, Phoebetria palpebrata, Procellaria aequinoctialis, Pterodroma cookilaria, Pterodroma lessonii, Pterodroma leucoptera, Pterodroma macroptera, Pterodroma macroptera, Pterodroma mollis, Pterodroma neglecta, Puffinus assimilis, Puffinus tenuirostris, Thalassarche bulleri, Thalassarche cauta, Thalassarche melanophrys, and Thysanoessa macrura. Molluscs found on the Cascade Seamount include Cuspidaria brazieri (Brazier’s spoon-shell), Cuspidaria erma (noble spoon-shell), Veprichlamys perillustris (shining scallop), Fusitriton magellanicus retiolus (Magellanic rock-whelk), and Sassia kampyla (curved rock-whelk). The deep water sea star Novodinia australis has been found on the Cascade Seamount.

It lives in the middle shore. In general it can be said that at high vertical heights on the shoreline the dog whelk is most threatened by biotic factors such as predation from birds and interspecific competition for food, but abiotic factors are the primary concern, creating a harsh environment in which it is difficult to survive. At low vertical heights it is biotic factors, such as predation from crabs and intraspecific competition, which cause problems. The upper limit of the range in which the dog whelk is generally found is approximately coincidental with the mean high water neap tide line, and the lower limit of the range is approximately coincidental with the mean low water neap tide line, so that the vast majority of dog whelks are found on the mid-tidal zone.
|
|
In experiments it has been shown that 50% of dog whelks die at 40 °C, and it can be assumed that at temperatures lower than this a smaller proportion will be killed off. Furthermore, the dog whelk has to excrete ammonia directly into water, as it does not have the adaptation possessed by many upper shore species which would allow it to produce uric acid for excretion without loss of water. When kept emersed for seven days at a temperature of 18 °C, 100% of dog whelks die, in contrast to many periwinkle species which can lose even more water than the dog whelk (i.e. more than 37% of their total body mass) but survive as a result of their ability to excrete toxic waste products more efficiently.

Engraved shell cup with avian imagery, from Spiro Mounds Artifacts found during excavations of the site included Mississippian culture pottery, beads made from shell, worked copper fragments and raw nuggets, close to 100 distinctive Cahokian style serrated flint arrowheads, and at least one perforated sharks tooth used as a necklace. Several caches of whelk shell cups along with numerous engraved shell fragments were found in excavations of the mound. One cache of six whelk cups and a local mussel shell is considered to be a dedicatory offering deposited upon the beginning of mound construction. Motifs found on the engraved shell and pottery sherds have been connected to the Braden style of the Southeastern Ceremonial Complex, and are considered the earliest known examples of some of the hallmarks of this style.

If the crows did not fly high enough, they would have little success in breaking the whelks' shells. However, the crows could waste valuable energy if they climb too high. In his model, Zach predicted the optimal height for crows to drop the whelks. To do this, Zach calculated the total distance each whelk was dropped before it was successfully broken.

As a predator Kellet's whelk feeds on dead or alive polychaetes, bivalves, sea snails, crustaceans, ascidians. Additionally, they are known to scavenge on dead fish, echinoderms, and cephalopods. Kelletia kelletii feeds with an extensible muscular proboscis which can be extended from the head region during feeding. Food is ingested by a muscular sucking action of the proboscis and a rasping of the radula.

In contrast, Marcus Island has a large mussel population, and almost no seaweed or rock lobsters. Whelks, Burnupena spp also have a large population density at Marcus Island. Rock lobsters brought to Marcus Island were quickly consumed by the whelks, which outnumbered them. This interaction showed a role reversal between a prey species (the whelk), and a predator species (the rock lobster).

Shells of species in this genus can grow to a length of 40 cm. They all have a long siphonal canal. The shells are generally a solid cream, light grey or tan in color, however the shell of the lightning whelk is marked with brown and white streaks. The shell of individuals can sometimes vary quite widely in coloration and sculpture.

Knobbed whelk shells Busycon carica ssp. eliceans The shell of most knobbed whelks is dextral, meaning that it is right-handed. If the shell is held in front of the viewer, with the spiral end up and the opening facing the viewer, the opening will be on the animal's right side. The shell is thick and strong and has six clockwise coils.

|
This allows shelter until more food is required, when foraging resumes. If waves are large or there is an excessive risk of water loss the dog whelk will remain inactive in sheltered locations for long periods. Mussels have developed a defensive strategy of tethering and immobilising with byssus threads any dog whelks invading their beds, leading to the whelks' starvation.

The larvae then settle on rocky surfaces. The brown mussel is a filter feeder and feeds on phytoplankton, zooplankton and suspended organic materials. It is plagued by the parasite Proctoeces maculatus and an unidentified bucephalid sporocyst which castrates both sexes. On the African coastline it is preyed upon by the whelk Nucella cingulata, lobsters, octopuses, gulls and the African black oystercatcher.

The other three top ports were Terminal Island, San Diego, and San Pedro. Dana Point is also an important port. Ex-vessel value from the 2008 commercial harvest of Kellet's whelks was approximately $132,700, with price per pound averaging $0.82 ($1.81 per kilogram). Since 1979, the fishery's ex-vessel value has ranged from $94 (1988) to approximately $136,000 (2007) and the ex-vessel price has ranged from $0.24 per pound ($0.53 per kilogram) in 1981 to $0.88 per pound ($1.94 per kilogram) in 1992. The average weight of a Kellet's whelk in a fishery is 150 g.California Department of Fish and Game (2011) "Review of selected California fisheries for 2010: coastal pelagic finfish, market squid, ocean salmon, groundfish, highly migratory species, dungeness crab, spiny lobster, spot prawn, kellet's whelk, and white seabass".

This whelk is found in shallow waters in the northeastern Pacific Ocean. Its range extends from the Chirikof Island in Alaska to Monterey Bay in central California. It is particularly common in British Columbia, Washington state and Oregon, but uncommon in California. It is found intertidally on rocky shores and in the shallow subtidal zone, and is found down to about on the Cobb Seamount.

Objects carved from bone include spatulas and toggles. A handle was made from red deer antler, and pendants were made from horse and dog teeth. Pointed bone tools were carved from sheep tibiae or roe deer metapodials. Shells had been perforated for use as pendants, using shells from Nucella lapillus (dog whelk), and Littorina obtusata – both of which species had to be transported from the coast.

Found in the Northeast of America, there are quahog clam shells that are often time used for the black and sometimes the white beads of these belts. Most often the Iroquois used various types of whelk spiral shells for the white beads. These were very important in the story of Hiawatha. Hiawatha was very full of grief because his daughters were murdered in the fight.

Leynes, Cullison, Chapter 2, pp. 9–10 The earliest evidence of human presence in Biscayne dates to about 2500 years before the present, with piles of conch and whelk shells left by the Glades culture. The Glades culture was followed by the Tequesta people, who occupied the shores of Biscayne Bay. The Tequesta were a sedentary community that lived on fish and other sea life, with no significant agricultural activity.

The inhabitants left numerous shell middens, composed primarily of oyster shells, but also including clam, scallop, whelk and conch shells. Fish of various kinds were another important component of the diet. Sea turtles, tortoises, alligators and deer were also consumed. Horticulture was absent or a late introduction, although the inhabitants of the southern end of the region (Pasco and Hernando counties) were growing maize at the time of first European contact.

Some species are polymorphic for different chromosome structural forms. The structural variation may be associated with different numbers of chromosomes in different individuals, which occurs in the ladybird beetle Chilocorus stigma, some mantids of the genus Ameles, the European shrew Sorex araneus. There is some evidence from the case of the mollusc Thais lapillus (the dog whelk) on the Brittany coast, that the two chromosome morphs are adapted to different habitats.

Real Lakshmi Conch (right side spinning) are estimated to occur only one per 100,000 conch shells. The shell of the lightning whelk on the other hand almost always opens on the right (when viewed with the siphonal canal pointing upwards). Valampuries with five plaits or folds in its cavity are known as 'Panchajanya' and are very rare. Most of the Indian Valampuries show presence of orange coloured inner lip.

Busycon whelks are scavengers and carnivores, equipped with a proboscis tipped with a file-like radula used to bore holes through the shells of barnacles, clams, crabs, and lobsters. They have a large, muscular foot with which they hold their victims. Small sharks, gulls, crabs, and other gastropods are known to feed upon them. The knobbed whelk, Busycon carica, is the second-largest species, growing up to 30 cm long.

Neptunea smirnia, the chocolate whelk, is a species of sea snail, a marine gastropod mollusk in the family Buccinidae, the true whelks. It was first described to science by William Healey Dall in 1919. The type specimen was collected from the Strait of Juan de Fuca in 114 fathoms of water. Neptunea smirnia fossils have been identified in pliocene epoch deposits, suggesting that this species is at least 2.5 million years old.

White beads were cut from the white part of the quahog or whelk shells. Iroquois peoples strung these shells on string in lengths, or wove them in belts. The shell most valued by the Native American tribes of the Pacific Coast from Alaska to northwest California was 'Dentalium', one of several species of tusk shell or scaphopod. The tusk shell is naturally open at both ends, and can easily be strung on a thread.

The capability of shell thickening by mussels has become a very effective defense mechanism. In the presence of predators a mussel is able to increase shell thickness 5 to 10 percent, which in turn makes opening the shell take 50 percent more time. Small mussels are also eaten by the dog whelk, Nucella lapillus. The blue mussel is host to a wide range of parasites, but these parasites usually do not cause much damage.

At the bottom of the Serripes zone, the fauna changes with the arrival of species previously unknown in the area. These include common whelk, Neptunea despecta, Serripes, Macoma calcarea and the wrinkled rock-borer (Hiatella arctica), but these species are now among the most common species of shellfish in Iceland.Leifur A. Símonarson & Jón Eiríksson (2008). Around 80 species of molluscs, mainly snail and bivalve species, have been found at the Serripes zone.

The Great Peacemaker gifted Hiawatha with the whelk shells and told him to put them on his eyes and ears and throat. These shells were a sign of healing and purity. Hiawatha used these shells to create unity The Wampum beads are the most significant part of the story of Hiawatha. The Iroquois Nation believes that the Peacemaker was the one who gifted them the first wampum belt, which later was titled the Hiawatha belt.

Disappearing or diminishing populations of whelks have been observed since the early 1970s, especially in the North Sea and the Wadden Sea. Additionally, vast beds of empty shells have been discovered where no living whelks are present. Imposex, the occurrence of male gonads on female whelks, has been detected since the early 1990s, and is thought to be a product of the shipping industry. Specifically, TBT has been shown to reduce viability of whelk populations.

Midden deposits are present along the entire foreshore with minor concentrations associated with rock shelters and extensive midden deposits visible beneath building foundations. The area would have provided rich marine resources for inhabitants, in terms of both food resources and shelter. Shellfish and fish such as Sydney rock whelk and Sydney rock oyster were integral to the diet of coastal Aboriginal tribes, as were snapper and bream. Both men and women spent considerable time fishing.

Veined rapa whelks have caused significant changes in the ecology of bottom-dwelling organisms, and have become marine pests in the Black Sea. Although scientists are not completely aware of the impacts of the whelk, they are very concerned about its potential impact on native Bay species. Studies are currently under way to help determine the whelk's spread in Chesapeake Bay, so that scientists can develop a model that will define potential impacts to the Bay's ecosystem.

Whitney, pp. 313–316. Female sea turtles return annually to nest on the shore, and manatees spend the winter months in the warmer water of the bay. The Calusa Indians had various uses for shells of marine invertebrates, due to the lack of dense rock with which to make tools. They used the horse conch (Triplofusus papillosus), left-handed whelk (Sinistrofulgur), and the Florida crown conch (Melongena corona) as drinking vessels, picks, hammers, knives and awls.

"Hero Twins" emerging from a crack in the back of a raccoon-faced Horned Serpent called a Sinti Shaui by the Choctaw.The horned serpent with the raccoon face is apparently the same as the Choctaw sinti shaui, a symbol of the earth. Townsend suggests that the two beings emerging from it are the hero Twins (in Winnebago, these would be the nephews of Bluehorn). The original was engraved on a marine whelk shell photographed as fig.

Species other than blue crab are often caught incidentally in crab pots, including fish, turtles, conch, and other crab species. In Georgia, hermit crabs (Pagurus spp.), channeled whelk (Busycon canaliculatum), spider crabs (Libinia spp.), and stone crabs (Menippe mercenaria) were the most common species observed as bycatch in commercial crab pots. Of important concern is the diamondback terrapin, Malaclemys terrapin. The blue crab and diamondback terrapin have overlapping ranges along the East and Gulf coasts of the United States.

The EOD lasts 70 ms and has a head-negative monophasic waveform. This electric organ is thought to function in communication, and may help potential mates locate one another. Young and adult little skates are preyed upon by sharks, other skates, teleost fishes (including cod, goosefish, sea ravens, longhorn sculpins, bluefish, and summer flounder), gray seals, androck crabs (Cancer irroratus). Their egg-cases are preyed on by the sea urchin Strongylocentrotus droebachiensis and the whelk Buccinum undatum.

One common example is it leaching from marine paints into the aquatic environment, causing irreversible damage to the aquatic life. Tributyltin has also been linked to obesity in humans, as it triggers genes that cause the growth of fat cells. Tributyltin is harmful to some marine organisms, including the dog whelk, it causes dog whelks to suffer from imposex; females develop male sexual characteristics such as a penis. This causes them to become infertile or even die.

The presence of exotic copper items in the two mounds along with busycon shells has led archaeologists to believe the peoples of the Mill Cove Complex were involved in long distance trade with Mississippian culture peoples to their west. Whelk shells and yaupon holly, two local products, were valuable elite commodities to the peoples of the Mississippian cultures, used to make shell gorgets, ritual drinking vessels, beads and columnella pendants and the ingredient for the black drink.

However, when the strike came the TUC did not want his assistance;Postgate, pp. 236 and 239 among the reasons for their distrust was Lansbury's continuing advocacy for the right of communist organisations to affiliate to the Labour Party—he privately opined that British communists on their own "couldn't run a whelk- stall".Postgate, pp. 237–38 Lansbury continued his private campaigns in parliament, saying "I intend on every occasion to ... hinder the progress of business".

Hydractinia echinata on a shell of a Common Whelk (Buccinum undatum) Hydractinia echinata forms pinkish-brown (when alive) or plain brown (when dead) patches on gastropod shells that are occupied by a hermit crab, often near the aperture of the shell.John Barrett and C M Young, Collins Pocket Guide to the Sea Shore (1958) p.48 The horny mat or hydrorhiza is about three millimetres thick. It consists of thick jagged spines that reach three millimetres in height.

Some organotin compounds are relatively toxic, with both advantages and problems. They are used for biocidal properties as fungicides, pesticides, algaecides, wood preservatives, and antifouling agents. Tributyltin oxide is used as a wood preservative. Tributyltin was used as additive for ship paint to prevent growth of marine organisms on ships, with use declining after organotin compounds were recognized as persistent organic pollutants with an extremely high toxicity for some marine organisms (the dog whelk, for example).

The mulberry whelk does not usually move around much when both crevices in which to hide and prey species are in the vicinity. This is in contrast to the rather similar Thais orbita which makes foraging movements up the beach well away from the sheltered niches to which it retreats at low tide. Favoured prey includes oysters and the limpet Patelloida latistrigata. The barnacle Chamaesipho columna was also eaten, but was avoided when more attractive prey was present.
|
|
Their sense of smell is very well-developed; they can sense chemical signals from their prey from a considerable distance with their osphradia. Many whelks are capable of boring through the shell of bivalves, and because of this, some species cause much harm in oyster farms. True whelks can even attack fish caught in a net by extending their probosces to twice the length of their own bodies. The female whelk lays spongy egg capsules with hundreds of eggs.

The shell of the sea snail Buccinum undatum (here shown live) is favoured by C. parasitic when the empty shell is pagurized (inhabited by a hermit crab) Although Calliactis parasitica will occasionally attach to stones or empty shells, it is typically found on a gastropod shell inhabited by a hermit crab, and several individuals may live on the same shell. In the British Isles, the hermit crab is usually Pagurus bernhardus, but other species may be associated with C. parasitica in other parts of its range. C. parasitica is thought to use a chemical signal to detect its favoured shell, that of the whelk Buccinum undatum, because it has been observed in aquaria to mount the shell of a living B. undatum, although the whelk ensures that the sea anemone does not remain there. The hermit crab Pagurus bernhardus is a common symbiont of C. parasitica Calliactis parasitica can survive without the hermit crab, and the hermit crab can survive without C. parasitica, but they associate with each other to their mutual benefit; this is known as mutualism.

This is in contrast to the mulberry whelk Morula marginalba which shares the same habitat but remains in an area where there are both crevices in which to hide and prey species on which to feed. The sexes are separate in the white rock shell. The eggs that develop in the female gonoduct are wrapped in a number of membranes to form an egg capsule. Several of these are joined together in an egg mass and attached to the substrate.

Since the 1980s, the abundance of harbour porpoises in the sea off Amrum and Sylt has been increasing and a protected marine area was created in 1999 to provide shelter for them. The number of other marine species is equally great, the hermit crab, the common whelk, and the lugworm are all among them. Of them, mainly the sand shrimps are commercially used by "harvesting" them from the seabed with cutters. The shrimps are then wrongly marketed as "crabs" (Krabben).

Carefully cut and shaped shell tools dating back 32,000 years have been found in a cave in Indonesia. In this region, shell technology may have been developed in preference to the use of stone or bone implements, perhaps because of the scarcity of suitable rock materials. The indigenous peoples of the Americas living near the east coast used pieces of shell as wampum. The channeled whelk (Busycotypus canaliculatus) and the quahog (Mercenaria mercenaria) were used to make white and purple traditional patterns.

Horseshoe crabs are used as bait to fish for eels (mostly in the United States) and whelk, or conch. However, fishing with horseshoe crab was banned indefinitely in New Jersey in 2008 with a moratorium on harvesting to protect the red knot, a shorebird which eats the crab's eggs. A moratorium was restricted to male crabs in Delaware, and a permanent moratorium is in effect in South Carolina. The eggs are eaten in parts of Southeast Asia, Johor and China.

In the 19th century, street food vendors in Transylvania sold gingerbread-nuts, cream mixed with corn, as well as bacon and other meat fried on top of ceramic vessels with hot coals inside. French fries, consisting of fried strips of potato, probably originated as a street food in Paris in the 1840s. Street foods in Victorian London included tripe, pea soup, pea pods in butter, whelk, prawns, and jellied eels. Mumbai, India has more than a half a million of street food vendors.

The knobbed whelk lives subtidally and is migratory, alternating between deep and shallow water, depending on the time of year. During the weather extremes of the summer and winter months, these sea snails live in deep water, at depths of up to 48 m. In the milder weather of the spring and fall they live in shallow water, on near-shore or intertidal mud flats and sand flats. On the shallow-water mud flats whelks prey on oysters, clams, and other marine bivalves.

Live channeled whelks for sale in a California seafood market Shells of the channeled whelk typically reach 5 to 8 inches in length. The shell is smooth and subpyriform (generally pear-shaped), with a large body whorl and a straight siphonal canal. Between the whorls there is a wide, deep channel at the suture, and there are often weak knobs at the shoulders of the whorls. Finely sculpted lines begin at the siphonal canal and revolve around the shell surface.

The mulberry whelk is found on the north and east coasts of Australia and on islands in the central Indo-Pacific Ocean. In Australia, its range extends from the north west tip to Twofold Bay in New South Wales. It is common on rocks in the intertidal zone where adults hide in cracks. It is also found in estuaries where it is known as the black oyster borer because it feeds on oysters where it is regarded as a pest.
|
|
The mulberry whelk is a predator feeding almost exclusively on molluscs and barnacles. It has an extensible rasping radula with which it drills a hole through it victim's shell. The process is believed to be assisted by the sulphuric acid it produces in its salivary glands which helps to soften and dissolve the calcium carbonate in the mollusc's shell. It then uses its radula to cut the soft body of its victim in pieces before sucking the semidigested mass out.

The object is a single piece of whelk shell that has an engraving of a mammoth on one surface while the opposite side is undecorated. The shell has two small perforations along one side where a cord would have been strung so as to allow the gorget to be worn around the neck. The depiction of the mammoth is oriented horizontally, along the shell, rather than vertically as is most common. This means that when worn, the mammoth is depicted with the head facing down.

Orizaba remains a wreck in the Norwegian Sea. When she foundered, the ship had mercury aboard. Accordingly, in 2008 Norway's National Institute of Nutrition and Seafood Research (NIFES) on behalf of the Norwegian Food Safety Authority tested cusk, blue mussel and whelk in the vicinity of the wreck for levels of heavy metals. NIFES found that mercury levels in all three species were within European Food Safety Authority limits and that the levels in cusk and blue mussel were no higher than normal for those species.

The recording also noted 2 foot stencils. The recorder noted that stencils at the south end of the shelter were covered by dust, and were therefore not fully recorded, and that potentially more stencils would be found in that area under the dust. The 1979 recording also noted that the shell midden was probably about 4 feet deep, was littered with rubbish, but generally undisturbed at that time. Observed shells included Anadara trapezia (Sydney Cockle), Pyrazus ebeninus (Hercules' Club Whelk) and Crassostrea commercialis (Sydney Rock Oyster).

Exotic material from other regions found at Caddoan Mississippian sites included colored flint from New Mexico, copper from the Great Lakes, conch (or lightning whelk) shells from the Gulf Coast, and mica from the Carolinas. The Spiro site is the only Mississippian site where an artifact from Mesoamerica has been found. This is a piece of black obsidian from Mexico, likely reaching this site through Caddoan Mississippian trade with peoples to the southwest. Using these valued materials, Mississippian artists created exquisite works of art expressing their cultural identity and their complex spiritual beliefs.

The dire whelk was first described by Lovell Augustus Reeve in 1846 as Buccinum dirum. In the early 20th century, William Healey Dall would come to the conclusion that the species belong to a genus up until then known only from the Atlantic fossil record, Searlesia. This remained the status quo for most of the century, with more living species from both the Atlantic and Pacific added to Searlesia until 1991, when Geerat J. Vermeij split the Pacific species into a separate genus Lirabuccinum with B. dirum as its type.

L. dirum is a medium-sized, elongated whelk with a strong heavy shell, growing to a length of . There are four or five whorls separated by shallow grooves, and several rounded axial ribs, mainly on the spire. The first whorl of the shell (and the second whorl in young individuals) is sculptured with many narrow, evenly-spaced spiral ridges, which are also visible on the inside of the outer margin of the aperture. The aperture is an elongated oval-shape and can be closed with a horny operculum.

Piles of conch and whelk shells left behind by Native Americans Native Americans were present in lower Florida 10,000 years ago, when ocean levels were low and Biscayne Bay was comparatively empty of water. Water levels rose from about 4000 years ago and inundated the bay. Archeologists believe any traces left by the peoples of that era are now submerged; none now exist on dry lands in the park. The Cutler Fossil Site, just to the west of the park, has yielded evidence of human occupation extending to at least 10000 years before the present.

A shell of Veined rapa whelk, side by side with its egg case Rapana venosa is dioecious, which means each individual organism belonging to this species is distinctly male or female. In this species' native range, mating occurs for extended periods of time, mainly during the winter and spring. It reproduces by internal fertilization, after which it lays clusters of egg cases that resemble small mats of white to yellow shag carpet, mainly during spring and summer. One adult female can lay multiple egg cases throughout the season.

The imposex phenomenon has been observed in the veined rapa whelk in Chesapeake Bay. Imposex is characterized by the development of masculine sexual organs in female individuals as a consequence of exposure to organic tin compounds, such as tributyltin (TBT). Such compounds are biocide and antifouling agents, commonly mixed in paints to prevent marine encrustations on boats and ships. For this reason, it is not uncommon for high concentrations of such compounds to be present in the sea water near shipyards and docking areas, consequently exposing the nearby marine life to its possibly harmful effects.

Detail of tip of arm showing tube feet extended Like other starfish in the family Asteriidae, Marthasterias glacialis is a predator and feeds mostly on bivalve molluscs and other invertebrates. It has been found that secondary metabolites known as saponins, found within the starfish's tissues, have a dramatic effect on the whelk Buccinum undatum. At low concentrations they cause the mollusc to withdraw from the vicinity of the starfish and at higher concentrations they cause convulsions in the mollusc's musculature. The sea urchins Strongylocentrotus droebachiensis and Psammechinus miliaris are also affected by the chemicals.

M. modiolus is found growing on hard substrates including shells and stones and the byssus threads of other mussels. Survival rates of young individuals are low but by the time they reach about 4 cm long, at an age of 4 years, individuals are too large and tough to be predated upon by starfish such as Asterias rubens, the whelk Buccinum undatum and crabs. Juveniles growing on byssus threads are more likely to survive than free living individuals and this results in the formation of cold-water reefs of mussels.Modiolus modiolus UK Marine SAC's Project.

Coldwater reefs built up by S. vermicularis take many years to develop and provide a hard substrate which other organisms use. The reefs around the United Kingdom support a diverse community of sessile invertebrates, including sponges, hydroids, ascidians, bryozoans, the worm Pomatoceros triqueter, the sea anemone Metridium senile and bivalves such as Chlamys spp., Modiolus modiolus and queen scallop, Aequipecten opercularis. Macrofauna include crabs such as Cancer pagurus, the sea urchins Echinus esculentus and Psammechinus miliaris, the brittle star Ophiothrix fragilis, the starfish Asterias rubens and the whelk Buccinum undatum.

This species is a familiar part of the marine fauna of the Northern Atlantic and is found on the shores of the United Kingdom, Ireland, France, Norway, Iceland, various other northwest European countries, some Arctic islands, and North America as far south as New Jersey. They prefer colder temperatures, and cannot survive at temperatures above 29 °C.Ten Hallers-Tjabbes, C.C., Everaarts, J.M., Mensink, B.P., & Boon, J.P.

The whelk predators used their own shell to open the shell of their prey, oftentimes breaking both shells of the predator and prey in the process. This led to the fitness of larger-shelled prey to be higher and then more selected for through generations, however, the predator’s population selected for those who were more efficient at opening the larger- shelled prey. This example is an excellent example of asymmetrical arms race because while the prey is evolving a physical trait, the predators are adapting in a much different way.

Noah Czerny was a student at Aglionby, but Barrington Whelk, the old Latin professor, used him as a sacrifice in a failed attempt to wake up the ley lines. He relies on energy of the ley lines or Blue Sargent in order to stay substantial. Over the course of the series, it is revealed that his spirit is decaying and he needs more energy in order to look normal. On his final appearance he sacrifices the memories his friends have of him in order to save Gansey's life.

The beaches and cliffs around the mouth of the River Camel are home to a variety of marine molluscs, and on beaches exposed to longshore drift one can also find shells washed up with the tide, particularly after westerly storms. Common limpet, blue mussel and the barnacle (Chthamalus stellatus) are commonly found on rocks that are covered at high tide, with dog whelk and common periwinkle found in tidal rockpools. The banded wedge shell and blunt tellin (Arcopagia crassa) can also be found as far upstream as Padstow.

This is a small hermit crab which tends to occupy shells of the netted dog whelk Tritia reticulata. These crabs are often present on flattish beaches composed of medium to fine grained sand where the waves sweep up the shore. When exposed, they rapidly bury themselves in the sand, using the enlarged left chela to stabilise themselves in the wet sand and limit the extent to which they are rolled about by the waves. Near Cádiz in southern Spain, there are three species of hermit crab, D. pugilator, Paguristes eremita and Pagurus forbesii.

Map showing finds Long-nosed god maskettes are artifacts made from bone, copper and marine shells (Lightning whelk) associated with the Mississippian culture (800 to 1600 CE) and found in archaeological sites in the American Midwest and Southeast. They are small shield-shaped faces with squared-off foreheads, circular eyes, and large noses of various lengths. They are often shown on Southeastern Ceremonial Complex representations of falcon impersonators as ear ornaments. Long and short nosed versions of the masks have been found in ten different states, with the majority found at sites in Illinois.

Whelks dropped from 3 meters and lower actually had traveled high total distances because they had to be dropped numerous times in order to be broken. On the other hand, whelks dropped from 5 meters and 15 meters were dropped approximately the same number of times to initiate a break; however, the crows would obviously have to climb higher to break a whelk at 15 meters than at 5 meters. Zach predicted 5 meters to be the optimal dropping height. The results indicated that the crows do follow this model, as the average dropping height was 5.2 meters.

In addition, at least in the Southwestern Atlantic (Río de la Plata, Uruguay), exotic invasive species such as the rapa whelk Rapana venosa, were reported massively bio-fouling immature green turtles, reducing buoyancy, increasing drag, and causing severe injuries to the carapace.Lezama, C., Carranza, A., Fallabrino, A., Estrades, A., Scarabino, F., & López-Mendilaharsu, M.

Predators of Semibalanus balanoides include the whelk Nucella lapillus, the shanny Lipophrys pholis, the sea star Asterias vulgaris, and nudibranchs. Although they have no eyes, barnacles are aware of changes in light, and withdraw into their shells when threatened. Parasites of S. balanus include Pyxinoides balani, a protozoan which lives in the barnacle's midgut, and Epistylis horizontalis, a ciliate which lives on the gills. The isopod Hemioniscus balani occurs from France to the Faroe Islands and the Oslofjord, and from Labrador to Massachusetts, and is a parasite of S. balanoides, effectively castrating the barnacle if it is heavily infested.

Leptasterias polaris is a major predator in the cold waters in which it lives. Young individuals are mostly found on rocks less than deep and feed on such bivalve molluscs as the blue mussel (Mytilus edulis) and Hiatella arctica. Older individuals move to deeper waters where the seabed is sand or mud and feed on clams such as the Greenland cockle (Serripes groenlandicus), Spisula polynyma, the blunt gaper (Mya truncata) and the Atlantic jackknife clam (Ensis directus) which they dig up with their tube feet. They also eat gastropod molluscs such as the common whelk (Buccinum undatum) and the American pelicanfoot (Arrhoges occidentalis).

In 1946, French archaeologist Francoise Henry excavated evidence of a 7th-century AD dye workshop on Inishkea North where the monks in an early Christian Monastery were producing it from the shells of the dog whelk The dye fetched high prices at the time it was in high demand. One letter in the Book of Kells would take 500 shells to get enough colour to decorate it. Purple was very important because in early Irish laws only the royalty could wear purple. The tradition came from the Roman tradition, who took it from the Greeks, who borrowed that tradition from the Phoenicians.

The earliest inhabitants of the Port Stephens region and particularly the land close to Port Stephens itself were the members of the Worimi Aboriginal tribe and their middens may be seen at many points along the beach. These middens, which are up to 12,000 years old, consist mainly of the remnants of pipis and whelk shells. As the beach is constantly reshaped by the winds some middens are concealed while new ones are revealed. A midden conservation area, where beach driving is not permitted due to the cultural significance of the middens, has been established on the beach.

Mississippian Hero Twins emerging from a crack in the back of a raccoon-faced Horned Serpent. Redrawn from an engraved whelk shell by artist Herb Roe. Possible representation of Hero Twins on an engraved shell gorget from Spiro Mounds, Oklahoma Many Native American cultures in the United States have traditions of two male hero twins. For instance, in the creation myth of the Navajo (called the Diné Bahaneʼ) the hero twins Monster Slayer and Born for Water (sons of Changing Woman) acquire lightning bolt arrows from their father, the Sun, in order to rid the world of monsters that prey upon the people.

Engraved whelk shell from the Craig Mound showing a tattooed figure Caddoan Mississippian peoples were connected to the larger Mississippian world to the east and other cultures to the southwest by trade networks which spanned the North American continent. Artifacts found in "The Great Mortuary" (Craig Mound) at the Spiro site included wood, conch shell, copper, basketry, woven fabric, lace, fur, feathers, and carved stone statues. Some artifacts came from as far away as Cahokia in Illinois, Etowah and Ocmulgee in Georgia, and Moundville in Alabama. Many featured the elaborate symbolism of the Southeastern Ceremonial Complex, a multiregional and pan-linguistic trade and religious network.

Narragansett favored teardrop-shaped shell pendants, and the claw pendants made of purple shell were worn by Iroquois in the Hudson Valley, around the Connecticut River. The Seneca and Munsee made shell pendants with drilled columns, decorated with a circular shell called a runtee. Whelk shells were carved into bird, turtle, fish, and other shaped pendants, as well as ear spools.Dubin 169, 174 Carved stone pendants in the Northeastern Woodlands date back as far as the Hopewell tradition from 1—400 CE. Bird motifs were common, ranging from the stylized heads of raptors to ducks.Dubin 157 Carved shells and incised animal teeth, especially bear teeth, have been popular for pendants.

Montaukett grave in Montauk. The only recognizable grave is that of Stephen Talkhouse The biggest recorded loss of life in the various skirmishes and conflicts in East Hampton was "Massacre Valley" in 1653 in Montauk when 30 members of the Montaukett tribe were killed by members of the Narragansett tribe at the foot of what is now Montauk Manor. The Montauketts had a thriving wampum (made from whelk shells on the East Hampton beaches) trade Connecticut tribes. The arrangements were disrupted in 1637 by the Pequot War which was to solidify English domination of New England and change the balance of power among Native American tribes.

The Etowah River is a tributary of the Coosa and Alabama rivers, and forms the border between the southern edge of the Ridge and Valley Appalachians and the Piedmont Plateau. Trade and tribute brought whelk shells from the Gulf of Mexico; copper, mica and flint from the Cumberland Plateau; and "galena, graphite, and an array of ochers to provide pigment for painting buildings, bodies, and works of art; greenstone and marble to furnish raw material for tools, weapons and ritual objects" from the Piedmont. The loamy riverbed soil could be easily tilled with digging sticks and stone and shell hoes. Its fertility was annually renewed by the river's floods.

TBT has been shown to harm many marine organisms, specifically oysters and mollusks. Extremely low concentrations of tributyltin moiety (TBT) causes defective shell growth in the oyster Crassostrea gigas (at a concentration of 20 ng/l) and development of male characteristics in female genitalia in the dog whelk Nucella lapillus (where changes in gonad characteristics are initiated at 1 ng/l). The international maritime community has phased out the use of organtin-based coatings. This phase-out of toxic biocides in marine coatings posed a severe problem for the shipping industry; it presents a major challenge for the producers of coatings to develop alternative technologies.

Some of the terraces and aprons on the mound seem to have been added to stop slumping of the enormous mound. Although the mounds were primarily meant as substructure mounds for buildings or activities, sometimes burials did occur. Intrusive burials occurred when a grave was dug into a mound and the body or a bundle of defleshed, disarticulated bones was deposited into it. Mound C at Etowah has been found to have more than 100 intrusive burials into the final layer of the mound, with many grave goods such as Mississippian copper plates (Etowah plates), monolithic stone axes, ceremonial pottery and carved whelk shell gorgets.

Since 1979, 89 percent of all harvested Kellet's whelks have been taken incidentally in lobster and crab traps when they enter to prey on bait or on injured crustaceans. The other method of take is diving. Commercial divers are required to have a commercial fishing license, and may only take whelks that are further than 1000 feet (305 meters) beyond the low tide mark, as the take of any snails is prohibited in the tidal invertebrate zone (Title 14, CCR, §123). Recreational take of Kellet's whelk by hand is allowed (Title 14, CCR, §29.05) outside of the 1000 foot (305 meter) tidal invertebrate zone.

A contemporary painting of Turtle, Red Horn and Storms as He Walks done in the style of a Southeastern Ceremonial Complex engraved whelk shell. The adventures of Red Horn are set out in a set of stories known as the "Red Horn Cycle". The Red Horn Cycle depicts his adventures with Turtle, the thunderbird Storms-as-He-Walks (Mą'e-manįga) and others who contest a race of giants, the Wąge-rucge or "Man- Eaters", who have been killing human beings whom Red Horn has pledged to help. In the episode associated with this name, Red Horn turns himself into an arrow to win a race.

This may be as a result of chemicals released into the water by the crabs because the thickness of the whelk's shell seems unaffected by the presence of Carcinus maenas, a recently introduced invasive species of crab that also feeds on whelks. A different response in shell morphology was evinced in the presence of the seastar. Here, the shell tended to get longer with a high spire, enabling the whelk to retract its soft tissues as far as possible from the seastar. If both crabs and seastars were present, the shell phenotype that tended to evolve reflected the response to the predator that caused the greatest mortality.

The whelk needs a few hours to penetrate the shell and thus living in the littoral zone is an advantage to the bivalve because the gastropod can attempt to bore through the shell only when the tide is in. Some bivalves, including the true oysters, the jewel boxes, the jingle shells, the thorny oysters and the kitten's paws, cement themselves to stones, rock or larger dead shells. In oysters the lower valve may be almost flat while the upper valve develops layer upon layer of thin horny material reinforced with calcium carbonate. Oysters sometimes occur in dense beds in the neritic zone and, like most bivalves, are filter feeders.

Anthropomorphic human headed avian plate from Spiro Spiro Mounds people participated in what archaeologists call the Southeastern Ceremonial Complex (SECC), a network of ceremonial centers sharing the Mississippian culture and similar spiritual beliefs, cosmology, ritual practices, and cult objects. The SECC was a vast trading network that distributed exotic materials for making ritual objects from all across North America. These included colored flint from New Mexico, copper from the Great Lakes, conch (or lightning whelk) shells from the Gulf Coast, and mica from the Carolinas. Other Mississippian centers also traded in these prized resources, but Spiro was apparently the only one that acquired obsidian from Mexico.

Shell columella (the central column of a conch or whelk shell, often used as a hammer) and tools with shark's teeth have also been found.Milanich 1995: 232, 235 The Cades Pond people heavily exploited the aquatic resources of their environment. A large midden at the Melton site on the north side of Paynes Prairie provided evidence for most of what is known of Cades Pond subsistence. Eighty-five percent of the 1500 individual animals used for food at one site came from aquatic habitats. Included were snails, clams, 12 species of fish, frogs, 7 species of turtles, 5 species of water snakes, alligator, 7 species of water birds, otter, and muskrat.

Relatively flat shell fields, of about in area, are in the interior of the shell works, separated from the shell ring by mangroves, with a series of mounds partly surrounding the shell fields. The shell fields have some very low ridges and shallow depressions and ponds. Schwadron suggests that the depressions may have been oyster roasting pits or the sites of structures. The shell fields consist primarily of small oyster shells with some conch and whelk shells, and many artifacts, including ceramics and shell tools.Schwadron: 135 The base level of the shell fields consists of a mixture of broken and unbroken oyster shell, with no artifacts and very little soil.

All of the copper pieces came to Lake Jackson by way of the Etowah site which shows that the two sites had a long-running relationship, trading their specific local prestige products to each other. The Etowahans prized the whelk shells from the Gulf Coast for the making of shell gorgets and ritual drinking cups and the Lake Jackson elites valued the prestigious Etowah plates and other copper objects. This monopoly on the shell trade by the Etowahans lasted until the fall of the chiefdom in about 1375, after which the elite status goods used in burials in Mound 3 come from other locations, mostly the northern Georgia and eastern Tennessee area.

Oval-shaped egg capsules are deposited in clusters on hard substrates, including rock reef, discarded mollusk shells, and other Kellet's whelks, with egg laying speculated to be favored on substrate already containing Kellet's whelk egg capsules. Egg deposition may occur over several days at several locations, or all within one day. Egg capsules generally contain between 400 and 1200 eggs, with the height of the capsule, and number of eggs directly correlating to the size of the spawning female. Egg capsule height generally ranges between 0.2 and 0.4 inches (6 and 9 millimeters) and capsules may occasionally contain up to 2200 eggs. Embryos begin development within the capsule for about 30–34 days.

The primary marine conservation features of Laxey Bay are maerl beds to the north and east, eelgrass meadows in Garwick Bay, kelp forest, rocky reef, the dog whelk (Nucella lapillus) population and relatively large numbers of the long-lived bivalve, the ocean quahog (Arctica islandica). Thornback ray, spotted ray and small-spotted catshark eggcases are regularly found on Garwick Beach, suggesting nearby breeding populations. Laxey Bay is also notable for its seabird populations, including breeding shag, black guillemot, Eurasian eider, herring gull, great black-backed gull and small numbers of lesser black-backed gull. red-billed chough, peregrine, Eurasian oystercatcher, Eurasian curlew, great cormorant, grey heron and northern fulmar are also commonly seen.

The Treatise on Invertebrate Paleontology (or TIP) published by the Geological Society of America and the University of Kansas Press, is a definitive multi- authored work of some 50 volumes, written by more than 300 paleontologists, and covering every phylum, class, order, family, and genus of fossil and extant (still living) invertebrate animals. The prehistoric invertebrates are described as to their taxonomy, morphology, paleoecology, stratigraphic and paleogeographic range. However, taxa with no fossil record whatsoever have just a very brief listing. Publication of the decades-long Treatise on Invertebrate Paleontology is a work-in-progress; and therefore it is not yet complete: For example, there is no volume yet published regarding the post- Paleozoic era caenogastropods (a molluscan group including the whelk and periwinkle).

" Tim Robey of The Daily Telegraph gave the film three out of four stars, saying "For all its properly surreal mayhem, this flick isn't quite as nimble or emotionally rounded as its predecessor." Sean O'Connell of The Washington Post gave the film one and a half stars out of four, saying "Kids will chuckle, for sure. But parents who were pleasantly surprised by the original film's intelligence will miss Lord and Miller's guiding hands, as what once felt so funny now leaves a stale taste." Kyle Smith of the New York Post gave the film one out of four stars, saying "Whelk, I hope the makers of Cloudy With a Chance of Meatballs earned a nice celery, but I'm afraid they made a hash of things.

Two live Kelletia lischkei snails A molecular phylogeny of Buccinidae based on the mitochondrial 16S rRNA gene suggested that Kelletia is a closely related to Penion, a true whelk genus with extant species distributed in waters off of New Zealand and Australia. Results of a further molecular phylogenetic studies using mitochondrial genomic and nuclear ribosomal DNA sequence data re-affirmed this relationship, and also demonstrated that Kelletia and Antarctoneptunea found in the southern Pacific and Southern oceans are sister clades. The common ancestor of the three genera most likely evolved in the southern Pacific Ocean, and a lineage leading to Kelletia dispersed over millions of years up the western coast of the Americas into the northern Pacific Ocean. Radulae and opercula morphology is similar between Penion and Kelletia.

The Assessment noted the presence of Sydney cockle and whelk shells on the surface elsewhere on the site, but in the context of building debris, and likely to have been moved downhill (by erosion or other disturbance). The Assessment indicated that "the rock shelter was probably the focus of midden making/consumption activity in the landscape", and therefore a curtilage from the rear boundary would include "all possible locations at the front of the shelter where intact deposit may be located sub-surface". Having regard to the painted stencils, the 2005 Assessment recorded what is possibly a third foot stencil. The Assessment noted that the site "would benefit from a detailed recording (including hand and foot stencil measurements and proper description, and the relationship between the motifs being recorded)".

Since the 1970s, the horseshoe crab population has been decreasing in some areas, due to several factors, including the use of the crab as bait in eel, whelk and conch trapping. According to the Horseshoe Crab Benchmark Stock Assessment Peer Review Report published by the Atlantic States Marine Fisheries Commission (ASMFC), the population continues to remain stable where biomedical is present in the Northeast and thrive and grow in the Southeast due to protection efforts – a trend spanning decades. Red knots feeding on horseshoe crab eggs in Delaware Conservationists have also voiced concerns about the declining population of shorebirds, such as red knots, which rely heavily on the horseshoe crabs' eggs for food during their spring migration. Precipitous declines in the population of the red knots have been observed in recent years.

The barnacle Balanus balanus and the hermit crab Pagurus bernhardus can often be seen in the vicinity and the squat lobster Munida rugosa may be hiding in crevices nearby.European Environment Agency A range of solitary sea squirts are often present including Ciona intestinalis, Corella parallelogramma, Polycarpa pomaria, Ascidia mentula and Ascidia virginea. Echinoderms such as the brittle star Ophiothrix fragilis are frequently seen with their arms protruding from rock cracks, whilst the starfish Asterias rubens and the sea urchins Echinus esculentus and Psammechinus miliaris occasionally form part of the community, as does the whelk Buccinum undatum. A survey was undertaken of the marine ecology in deep water off County Kerry in Ireland, The rock and boulders were covered with a fine silt and there were coralline crusts over most surfaces.

Its adaptations include a modified radula (a toothed chitinous structure) to bore holes in the shells of prey, complemented by an organ on the foot which secretes a shell- softening chemical. When a hole has been formed paralysing chemicals and digestive enzymes are secreted inside the shell to break the soft body down into a 'soup' which can be sucked out with the proboscis. The plates of barnacles can be pushed apart with the proboscis, and the entire individual is eaten in about a day, although larger animals such as mussels may take up to a week to digest. Feeding only occurs when conditions are conducive to such an activity, and during these times the dog whelk consumes large quantities of food so that the gut is always kept as full as possible.
