A group of snorkeling seniors has helped scientists collect data about greater sea snakes in New Caledonia.
|
|
Greater sea snakes have distinctive markings on their tails, so individuals can be easily identified from photographs.
|
|
During the first three years of the study, the pair only managed to catalog 603 greater sea snakes.

Normally people avoid the ocean when it turns to marshmallow fluff, due to an influx of sea snakes, according to the BBC.
|
|
Since 2017, the women have documented 250 greater sea snakes, and their data contributions have been published in the science journal Ecosphere.
|
|
Most sea snakes live far offshore and are dangerous to handle, so few scientists have the means or desire to study them.
|
|
Could sea snakes be doing the same thing, using melanin-rich skin as a dumping ground for the pollutants encountered in their surroundings?
|
|
Photographs taken by the grandmothers demonstrated that, within a 25-month period, at least 140 greater sea snakes visited the Baie des Citrons.
|

They concluded the body of water was warm and shallow and, less pleasantly, was home to five-foot-long catfish and 40-foot-long sea snakes.
|
|
Water temperatures in this area can reach as high as 12010 degrees F (32.6 degrees C), which is dangerously close to what sea snakes can endure.
|
|
Collectors have already started to poach the sea snakes, and climate change threatens to make large swaths of ocean water too warm for them to survive.

While most sea snakes are quite venomous, the turtle-headed sea snake has lost much of its venom potency, because fish eggs aren't exactly hard to kill.
|

A group of women who have dubbed themselves the "Fantastic Grandmothers" helped scientists discover a population of rare, venomous sea snakes while snorkeling together in the South Pacific.
|
|
Near New Caledonia, a French archipelago in the southern Pacific Ocean, turtle-headed sea snakes swim around, gobbling up fish eggs from the bottoms of bays and lagoons.
|
|
To find out, the researchers tested the shed skins of black and banded sea snakes for more than a dozen trace minerals, including zinc, arsenic, cobalt and nickel.
|
|
They chose the Baie des Citrons as the venue for this study, despite greater sea snakes having only been seen there six times in the past eight years.
|
|
"The study zone is in the most touristic bay in Noumea, so I often meet people when I am doing field work on sea snakes," Goiran told the Guardian.
|
|
While screening them against common venoms, he isolated some nanoparticles that bind with and neutralize two poisons produced by snakes like cobras, kraits, coral snakes, sea snakes and mambas.
|
|
"As soon as the grandmothers set to work, we realized that we had massively underestimated the abundance of greater sea snakes in the bay," Dr. Goiran wrote in the study.

Seven women, who are all in their 60s and 70s and known as the "Fantastic Grandmothers," helped scientists discover a population of rare, venomous sea snakes while snorkeling together in the South Pacific.
|
|
What's more, these waters can become anoxic, where the dissolved oxygen falls to incredibly low levels (sea snakes pull oxygen from the water through their skin, so anoxic waters could cause them to suffocate).
|
|
Beachgoers reported seeing several of the yellow-bellied sea snakes, or Pelamis platura, which lead entirely aquatic lives usually in tropical waters, about 200 miles south of Sydney after a spell of stormy weather.
|
|
What they did: The scientists examined populations of turtle-headed sea snakes and museum specimens throughout Southeast Asia and Australia, and found a clear association between dark coloration and urban pollution or military activity.
|
|
But now, in a report published last week in Current Biology, Dr. Shine and his colleagues suggested that the varied coloration of sea snakes is probably an adaptation that helps them deal with pollution.
|

They swim nearly two miles a day, five days a week at the Baie des Citrons beach in Nouméa, the capital city of New Caledonia, looking for venomous greater sea snakes to take pictures of.
|
|
This was weird, he thought, because in the rest of their range, from northern Australia to Vietnam, about 95 percent of the sea snakes wrapped themselves in skins of blue and black bands or speckles.

The urban-adjacent reefs that contain high levels of trace metals do so invisibly, the only observable consequence being the subtle evolutionary impact upon turtle-headed sea snakes, which take in and accumulate the pollutants from their diet of fish eggs.
|
|
Meanwhile, the water cobra, Naja annulata, lost its hooding abilities and its flesh-destroying venom when it adapted to the water, but it developed a different kind of weapon—a neurotoxic venom, similar to those of other aquatic sea snakes.

Illustration: Carl Buell (AMNH)The Sahara might seem like one of Earth's most lifeless regions today, but its fossils show it was once a vast seaway filled with giant fish and some of the largest sea snakes the planet has ever seen.
|
|
Now, a newly published study in the journal Current Biology has revealed that in certain locations—usually near cities or human activities—the sea snakes are adapting to presence of human pollution, darkening their skin as a means of avoiding the effects of pollutants.
|
|
The team of researchers, based out of New Caledonia, Australia, and France, investigated this question by examining turtle-headed sea snakes living along the coastlines of the South Pacific island of New Caledonia and tropical Australia, in both urban, human-impacted areas and undeveloped, pristine reefs.
|
|
The scientists surveyed the color variants of turtle-headed sea snakes across their geographic range, and confirmed that dark, stripeless snakes were very common in reefs near urban areas or industrial activity, but in less impacted regions, the more typical banded or blotched patterns were dominant.

Here were the sun-soaked swimming pools, the full-scale basketball court, the four water slides tangled like enormous sea snakes and the three-story ropes course with 153 different elements, including the Escape's star feature: a pair of planks cantilevering over the ocean on either side.
|
|
So when turtle-headed sea snakes cast aside their old rags, they are also permanently expelling a big dose of trace metals—and the researchers found that the urban-industrial populations are exploiting the benefits of this ability, shedding their skins more frequently than their clean-living relatives.

"Because the robot design mimics the sea snake we get this lovely feedback loop – the biology informs the design of the robot, which not only records new observations of the sea snakes but generates new information about the link between form and function," University of Adelaide researcher told National Geographic.
|
|
The fossils they found were weird and often very large, including a 5-foot-long catfish, 40-foot-long sea snakes, and other large fish, as well as relatives of today's crocodiles, sharks, and elephants, according to the synthesis of their findings in the Bulletin of the American Museum of Natural HistoryBut why were the fish so big?

Sea kraits are a genus of venomous elapid sea snakes, Laticauda. They are semiaquatic, and retain the wide ventral scales typical of terrestrial snakes for moving on land, but also have paddle-shaped tails for swimming. Sea kraits are often confused with another group of aquatic reptiles, the sea snakes. However, unlike the fully aquatic ovoviviparous sea snakes, sea kraits are oviparous and must come to land to digest prey and lay eggs.

Reptiles which inhabit or frequent the sea include sea turtles, sea snakes, terrapins, the marine iguana, and the saltwater crocodile. Most extant marine reptiles, except for some sea snakes, are oviparous and need to return to land to lay their eggs. Thus most species, excepting sea turtles, spend most of their lives on or near land rather than in the ocean. Despite their marine adaptations, most sea snakes prefer shallow waters nearby land, around islands, especially waters that are somewhat sheltered, as well as near estuaries.

Emydocephalus is a genus of sea snakes in the family Elapidae. Unlike most sea snakes, all species of Emydocephalus, have an absence of teeth on their dentary and palatine bones, and lack venom. The dentary and palantine bones bear only a row of papillae. Emydocephalus does, however, bear fangs and many small pterygoid teeth.
|
|
It has a number of openings of various sizes that lead to an underground lagoon where sea snakes and bats reign.
|
|
Tetrapods comprise the dominant megafauna of most terrestrial environments and also include many partially or fully aquatic groups (e.g., sea snakes, penguins, cetaceans).
|
|
Hydrophiid snakes, otherwise known as sea snakes, have only recently evolved from terrestrial elapids. Sea snake scales differ from that of terrestrial snakes because they are rugose and wrinkled. Male sea snakes scale rugosity is more developed than that of the females snakes. The male turtle headed sea snake, Emydocephalus annulatus, provides an interesting case study because of their unique scales.
|
|
Hydrophis is a genus of sea snakes. They are typically found in Indo- Australian and Southeast Asian waters. Currently, around 36 species are recognized.
|
|
The many-banded krait was more similar to the Australian elapids, Laticauda and true sea snakes than they were to numerous elapids they were compared to.
|
|
As with "true" sea snakes, H. semperi is piscivorous, feeding primarily on the numerous fish species that are known to dwell in Taal Lake's murky waters.
|
|
They are often spotted or striped in colour, mimicking the appearance of venomous sea snakes to deter predators. Often, they are washed ashore by large storms.
|
|
All snakes can laterally undulate forward (with backward-moving waves), but only sea snakes have been observed reversing the motion (moving backwards with forward-moving waves).
|
|
This is a common and widespread species, but little is known about its biology. During the mating season for this species it is not uncommon for sailors to see thousands of Hydrophis lapemoides sea snakes on the surface of the sea. Where Dolphin pods are seen, these masses of sea snakes are not noted, and it is suspected that the Dolphin is a natural predator of H. lapemoides.
|
|
Some marine reptiles also occasionally rest and bask on land. Sea snakes, crocodiles and marine iguanas only dive in inshore waters and seldom dive deeper than 10 m.
|

Although sea snakes are known for extremely potent venom, about 80% of reported bites end up being dry. It is estimated that each year 15,000 to 75,000 fisherman are bitten by sea snakes. The advent of antivenom and advances in emergency medicine have reduced fatalities to about 3% of snakebite cases. The highly venomous beaked sea snake is responsible for more than 50% of all sea snake bites, as well as the majority of envenomings and fatalities.
|
|
Sea kraits are semiaquatic, so have morphological adaptations to both land and sea. Laticauda species show traits intermediate between those of sea snakes and terrestrial elapids. They have a vertically flattened and paddle-shaped tail (similar to sea snakes) and laterally positioned nostrils and broad, laterally expanded ventral scales (similar to terrestrial elapids). Their body has a striped pattern, nasal scales are separated by inter-nasals scales, and the maxillary bone extends forwards beyond the palatine bone.

The documentary was largely filmed around Irwin's research boat, Croc One. The pair filmed and sometimes even captured several deadly sea animals, including stonefish, sea snakes, great white sharks, cone snails, blue-ringed octopuses, saltwater crocodiles and perhaps the world's deadliest venomous animal, the box jellyfish. According to Steve Irwin, one of the specimens, a Stokes' sea snake, was the largest he had seen. The team of researchers harvested venom from the stonefish and some of the sea snakes.
|
|
Stokes's sea snakes sometimes form migrating groups in the thousands, drifting in meter-long slicks in the Strait of Malacca. They are ovoviviparous, producing small broods of five young each mating season.

These sea snakes can have up to 44 dorsal bands that are grayish black to black that span across the whole length of the body. They have large head scales, and like many other sea snakes, they have nostril valves to prevent water from getting into their lungs while diving. The body scales are imbricate, and in 37–49 rows at the mid-body. The ventral scales are usually undivided and about as wide as, or slightly wider than, neighboring scales of which there are approximately 345–432.
|
|
The biggest piece of evidence for this as a case of coevolution is that eels that are favored by sea snakes as prey have unusually high tolerances to the venom of the sea snake. Studies have analyzed the resistance of four species of eels to two different sea snakes: one is a dietary generalist and the other is an eel specialist. The eels were more resistant to the venom of the eel specialist sea snake. Non-prey fishes exhibited very low levels of resistance to the sea snake venom, further supporting coevolution.

The Impotent Sea Snakes were an American rock'n'roll band from Tampa, Florida, United States, known for their sexually explicit lyrics and performances, and probably best known for their most high profile, publicized, and prolific touring period which lasted roughly from 1996 until 2004. The band put out three albums: Too Cool for Rock n' Roll (EP, 1984) which was re-released in 1986 minus two songs, "Honey Dippers In Love" and "Heatwave" but with eight additional new songs; God Save the Queens (1995), Everything in Excess (2001), and one officially released DVD: Impotent Sea Snakes Live in Germany (2005). The band also appeared on HBO's Real Sex TV series.

One can still find craters and unexploded bomb shells in the island. Fish eagles are thriving in this island primarily feeding on sea snakes and fish. A species of mongoose was also spotted in the island confirming mammalian inhabitants apart from bats. Whale sharks were also spotted by snorkellers.

Most of the Pacific Islands are free of terrestrial snakes; however, sea snakes are common in the Indian Ocean and tropical Pacific Ocean, but are not found in the Atlantic Ocean or the Caribbean, Mediterranean or Red Seas. While the majority of species live close to shorelines or coral reefs, the fully pelagic yellow-bellied sea snake can be found in the open ocean. Over 50% of bites inflicted by sea snakes, which are generally not aggressive, occur when fishermen attempt to remove snakes which have become tangled in fishing nets. Symptoms may appear in as little as 5 minutes or take 8 hours to develop, depending on the species and region of the body bitten.

Brachyurophis fasciolatus belongs to one of two burrowing clades of taxa found within Australian elapids and sea snakes.Sanders, K. L., Lee, M. S. Y., Leys, R., Foster. R., & Scott Keogh, J. (2008). Molecular phylogeny and divergence dates for Australasian elapids and sea snakes (hydrophiinae): evidence from seven genes for rapid evolutionary radiations.

|
They also have independent evolutionary origins into aquatic habitats, with sea kraits diverging earlier from other Australasian elapids. Thus, sea kraits and sea snakes are an example of convergent evolution into aquatic habitats within the Hydrophiinae snakes. Sea kraits are also often confused with land kraits (genus Bungarus), which are not aquatic.

Sea serpents were giant cryptozoological creatures once believed to live in water, whether sea monsters such as the Leviathan or lake monsters such as the Loch Ness Monster. If they were referred to as "sea snakes", they were understood to be the actual snakes that live in Indo-Pacific waters (Family Hydrophiidae).

During 1933, two Japanese fishermen discovered a breeding ground of sea snakes around the island. It was believed that the locals were taught by the Japanese on how to catch the sea snakes, process the skins and even how to deal with snake bites. The Island of Gato was previously under the administrative part of the Province of Masbate in Bicol Region of the Philippines but is more near to Daanbantayan. The supervision of the island started during 1997, when Daanbantayan passed a resolution declaring the island as a sea snake and fish sanctuary and assigning the Cebu State College of Science and Technology - College of Fisheries, Daanbantayan Campus which is now Cebu Technological University to safeguard and develop the island for research purposes.

Upon locating females, the reception of female skin lipid pheromones by tongue-flicking males is necessary for males to continue courtship and mating. Turtle-headed sea snakes are sexually dimorphic: the females of this species grow larger than males, and the rugosity of the scales is also greatly increased in males compared to females.

Different snakes are called water snakes. "Water snake" is also sometimes used as a descriptive term for any snakes that spend a significant time in or near fresh water, such as any species belonging to the family Acrochordidae. They should not be confused with sea snakes, which live primarily or entirely in marine environments.
|
|
The sea kraits (Laticauda spp.) are the sea snakes least adapted to aquatic life. Their bodies are less compressed laterally, and they have thicker bodies and ventral scaling. Because of this, they are capable of some land movement. They spend much of their time on land, where they lay their eggs and digest prey.

This species attains a length of . Zebra sharks are nocturnal and spend most of the day resting motionless on the sea floor. At night, they actively hunt for molluscs, crustaceans, small bony fishes, and possibly sea snakes inside holes and crevices in the reef. Though solitary for most of the year, they form large seasonal aggregations.

In addition to Balinese mythology, the temple was significantly influenced by Hinduism. At the base of the rocky island, venomous sea snakes are believed to guard the temple from evil spirits and intruders. The temple is purportedly protected by a giant snake, which was created from Nirartha's selendang (a type of sash) when he established the island.

In 1976 and 1988, ex officio trustees from various government institutions were added to the board. The park underwent various renovation after 1994, including an aquarium for sea snakes and turtles and restoration of enclosures and additional facilities. In 1997, the park was renamed as the Chennai Snake Park, following the renaming of the city of Madras in 1996.

McDowell's findings in regard to the sister-group of Bungarus and the sea snakes (Hydrophiinae) family, propose that the kraits might just be a per- mutable clade between the elapidae "palatine-erectors" and the hydrophiinae "palatine draggers". Two genera within the subfamily Hydrophiinae in particular, support McDowell's hypothesis. The two genera are Salomonelaps and Loveridgelaps due to many shared characteristics. Mao et al.

This shark typically reaches lengths of . The pigeye shark is an apex predator that mostly hunts low in the water column. It has a varied diet, consisting mainly of bony and cartilaginous fishes and also including crustaceans, molluscs, sea snakes, and cetaceans. This species gives birth to live young, with the developing embryos sustained to term via a placental connection to their mother.

Aipysurus eydouxii, commonly known as the beaded sea snake, marbled seasnake, or spine-tailed seasnake, is a species of sea snake in the family Elapidae. This species of snake is unusual amongst sea snakes in that it feeds exclusively on fish eggs. As part of this unusual diet, this species has lost its fangs, and the venom glands are almost entirely atrophied.
|
|
It may attain a snout-to-vent length (SVL) of . Its coloration, which consists of dark crossbands on a bluish grey ground color dorsally, and which is uniform pale yellow or cream ventrally, is similar to that of other sea snakes. However, K. annandalei can be identified by its high number of dorsal scale rows, 74–93 at midbody.Das I (2006).

Because males are smaller, they crawl and swim faster than females. Body adaptations, especially a paddle-like tail, help yellow-lipped sea kraits to swim. These adaptations are also found in more distantly related sea snakes (Hydrophiinae) because of convergent evolution. However, because of the differences in motion between crawling and swimming, these same adaptations impede the snake's terrestrial motion.
|
|
These snakes are generally found in the coast and coastal islands of India. They are amongst the most common of the 20 kinds of sea snakes found in that region. They are active both during the day and at night. They are able to dive up to 100 m and stay underwater for a maximum of five hours before resurfacing.

Risk factors for bites include working outside with one's hands such as in farming, forestry, and construction. Snakes commonly involved in poisonings include elapids (such as kraits, cobras and mambas), vipers, and sea snakes. The majority of snake species do not have venom and kill their prey by squeezing them. Venomous snakes can be found on every continent except Antarctica.

The Pacific goliath grouper is found on offshore rocky reefs as adults, although it has also been recorded in inshore areas. The juveniles inhabit mangroves, estuaries, lagoons and bays. It has been recorded feeding on sharks, rays, crustaceans, cephalopods, other fishes and even sea snakes and mammals. Little is known about its biology but it is thought to be similar to the Atlantic goliath grouper.

Venom emitted from some types of cobras, almost all vipers and some sea snakes causes necrosis of muscle tissue. Muscle tissue will begin to die throughout the body, a condition known as rhabdomyolysis. Rhabdomyolysis can result in damage to the kidneys as a result of myoglobin accumulation in the renal tubules. This, coupled with hypotension, can lead to acute kidney injury, and, if left untreated, eventually death.

Orchid Island hosts many tropical plants species, sharing many species with tropical Asia but also many endemics: there are 35 plant species found nowhere else. For example, Pinanga tashiroi is a species of palm tree found nowhere else than Orchid Island. Green sea turtles make nests on the island, which is surrounded by coral reefs. Four species of sea snakes inhabit the waters around the island.

Squid, octopus, cuttlefish, shrimp, and mantis shrimp are also taken, as well as carrion and smaller sharks and rays, though this is rare. Off northern Australia, this species is known to consume sea snakes, including Acrochordus granulatus, Hydrelaps darwiniensis, Hydrophis spp. and Lapemis hardwickii. Sharks off Palmyra Atoll have been documented preying on seabird chicks that have fallen out of their nests into the water.

Terrestrial elapids are found worldwide in tropical and subtropical regions, mostly in the Southern Hemisphere. Most prefer humid tropical environments, and so are not found in the Sahara or Middle East, although some can be found in Mexican and Australian deserts. Sea snakes occur mainly in the Indian Ocean and the south- west Pacific. They occupy coastal waters and shallows, and are common in coral reefs.

The diet is largely local species of fish, although a favoured target in Australia is known to be mullet when available. Occasional records are given for other marine life—sea snakes, molluscs and crustaceans—and for terrestrial species of reptiles, insects, birds and mammals. They are known to capture sea birds in flight. Ospreys have vision that is well adapted to detecting underwater objects from the air.

Diving weddell seals Air-breathing marine vertebrates that have returned to the ocean from terrestrial lineages are a diverse group that include sea snakes, sea turtles, the marine iguana, saltwater crocodiles, penguins, pinnipeds, cetaceans, sea otters, manatees and dugongs. Most diving vertebrates make relatively short shallow dives. Sea snakes, crocodiles and marine iguanas only dive in inshore waters and seldom dive deeper than 10 m, but both of these groups can make much deeper and longer dives. Emperor penguins regularly dive to depths of 400 to 500 m for 4 to 5 minutes, often dive for 8 to 12 minutes and have a maximum endurance of about 22 minutes. Elephant seals stay at sea for between 2 and 8 months and dive continuously, spending 90% of their time underwater and averaging 20 minutes per dive with less than 3 minutes at the surface between dives.

Along the shores of Astola and Ormara beaches of Balochistan and Hawk'e Bay and Sandspit beaches of Sindh are nesting sites for five endangered species of sea turtles: green sea, loggerhead, hawksbill, olive ridley and leatherback. Sea snakes such as yellow-bellied sea snake are also found in the pelagic zone of the sea. The wetlands of Pakistan are also a home to the mugger crocodile who prefer freshwater habitat.

A. eydouxii eats the eggs of fish. Relative to other sea snakes, it has several derived characteristics related to its special diet. These include strong throat musculature, consolidation of lip scales, reduction and loss of teeth, greatly reduced body size, and (due to a dinucleotide deletion in the 3FTx gene) much reduced toxicity of the venom. Only one other species of sea snake, Emydocephalus annulatus, shares A. eydouxii’s eggs-only diet.

Cutaneous respiration, or cutaneous gas exchange, is a form of respiration in which gas exchange occurs across the skin or outer integument of an organism rather than gills or lungs. Cutaneous respiration may be the sole method of gas exchange, or may accompany other forms, such as ventilation. Cutaneous respiration occurs in a wide variety of organisms, including insects, amphibians, fish, sea snakes, turtles, and to a lesser extent in mammals.

The elegant sea snake (Hydrophis elegans) is a highly venomous sea snake in the family Elapidae. They are found off the coast of Western Australia, Northern Territory of Australia, and Queensland Australia. The elegant sea snake is a medium, and slender animal growing to a length of , although in 2008 one was found at a length of . Like many other sea snakes, the elegant sea snake has a laterally compressed tail that aids in swimming.
|
|
Life expectancy of the snake is about fifteen years, sometimes a bit longer. While there are not many threats to the Aipysurus laevis, man-made dangers do exist for it. Prawn trawls are one of the greatest threats for the creature, up to 50% of olive sea snakes caught in trawls are killed, while the ones that survive usually suffer injuries. Death from prawn trawls often comes either from drowning or being crushed.

Based on molecular sequencing and fossil dating, Neoaves appeared to radiate after the K–Pg boundary. They even produced giant, flightless forms, such as the herbivorous Gastornis and Dromornithidae, and the predatory Phorusrhacidae. The extinction of Cretaceous lizards and snakes may have led to the radiation of modern groups such as iguanas, monitor lizards, and boas. On land, giant boid and enormous madtsoiid snakes appeared, and in the seas, giant sea snakes radiated.

This is a list of reptiles of Sri Lanka. The reptilian diversity in Sri Lanka is higher than the diversity of other vertebrates such as mammals and fish with 181 reptile species. All extant reptiles are well documented through research by many local and foreign scientists and naturalists. Sri Lankan herpetologist, Anslem de Silva largely studied the biology and ecology of Sri Lanka snakes, where he documented 96 species of land and sea snakes.

The Philippine Sea hosts an exotic marine ecosystem. About five hundred species of hard and soft corals occur in the coastal waters and 20 per cent of the worldwide known shellfish species are found in Philippine waters. Sea turtles, sharks, moray eels, octopuses and sea snakes along with numerous species of fish such as tuna can commonly be observed. Additionally, the Philippine Sea serves as spawning ground for Japanese eel, tuna and different whale species.

Guitarfishes and other cartilaginous fishes are preyed upon by the pigeye shark, particularly off South Africa. Though the pigeye shark will take prey from anywhere in the water column, it tends to hunt close to the sea floor. An apex predator, it feeds mainly on teleost fishes such as croakers, flatfishes, and cutlassfishes, and to a lesser extent on cartilaginous fishes, cephalopods, and decapod crustaceans. It has also been recorded eating gastropods, sea snakes, dolphins, and whale carrion.

On dry land, a yellow- lipped sea krait can still move, but, on average, at only slightly more than a fifth of its swimming speed. In contrast, most other non-Laticauda sea snakes are virtually stranded on dry land. When hunting, yellow-lipped sea kraits frequently head into deep water far from land, but return to land in order to digest, shed skin, and reproduce. Individual yellow-lipped sea kraits return to their specific home islands, exhibiting philopatry.

No bird species is fully aquatic, as all must lay and incubate their amniotic eggs, as well as begin raising their young, on land or ice. Similarly among marine reptiles, sea turtles are almost fully aquatic, but must come ashore to lay eggs. Marine iguanas and partly marine crocodiles (such as the saltwater crocodile and the American crocodile) are all semiaquatic. Most sea snakes are ovoviviparous (live-bearing) and fully aquatic (the exceptions being the oviparous, semiaquatic sea kraits).

The tropical ocean in the game is full of different life forms. This ranges from small fish, sea turtles, rays, lionfish, sea snakes, crown-of-thorns starfish, swordfish, whales, as well as the most dangerous enemies in the game - sharks. There are different types of sharks, some being harmless, while others are life threatening, like the Great Whites. Sharks can directly attack the player, or they can also bump into the player’s raft, potentially flipping it over.

Elapids may display a series of warning signs if provoked, either obviously or subtly. Cobras and mambas lift their inferior body parts, expand hoods, and hiss if threatened; kraits often curl up before hiding their heads down their bodies. In general, sea snakes are able to respire through their skin. Experiments with the yellow-bellied sea snake, Hydrophis platurus, have shown that this species can satisfy about 20% of its oxygen requirements in this manner, allowing for prolonged dives.

Hydrophis semperi, commonly known as the Lake Taal snake, Garman's sea snake, the Philippine freshwater sea snake, and the Luzon sea snake, is a rare species of venomous sea snake found only in a single lake on the island of Luzon in the Philippines. It is noted for being one of two known species of sea snakes that are known to be found almost-exclusively in freshwater. The other freshwater sea snake species is Laticauda crockeri.

These, on reaching adult size, probably had few, if any, predators that could harm them. The eel- like tail of Cymbospondylus made up almost half the total body length, and it is possible that the tail was used as a primary swimming mechanism. Like present day sea snakes, Cymbospondylus probably swam by wriggling its body from side to side. The paddle-like limbs of Cymbospondylus would primarily have been underwater stabilizers, and for slowing down the ichthyosaur's swimming speed.

The tiger shark is a solitary, mostly nocturnal hunter. It is notable for having the widest food spectrum of all sharks, with a range of prey that includes crustaceans, fish, seals, birds, squid, turtles, sea snakes, dolphins, and even other smaller sharks. It also has a reputation as a "garbage eater", consuming a variety of inedible, man-made objects that linger in its stomach. Though apex predators, tiger sharks are sometimes taken as prey by groups of killer whales.

The pattern reverses during January and February. Early navigators would have exploited these seasonal winds, navigating by the stars, the color of the water, the presence of sea snakes, and observation of the flights of sea crows and other homing birds. The ships of Kalinga were not able to make long sea voyages without stopping along the way for food and water. Ships outbound from Tamralipta would have followed the Burmese coast, stopping at the Nicobar islands, a one-month journey.

It typically attains a length of . The blacktip reef shark has extremely small home ranges and exhibits strong site fidelity, remaining within the same local area for up to several years at a time. It is an active predator of small bony fishes, cephalopods, and crustaceans, and has also been known to feed on sea snakes and seabirds. Accounts of the blacktip reef shark's life history have been variable and sometimes contradictory, in part reflecting geographical differences within the species.

Hydrophis donaldi, or the rough-scaled sea snake is a unique species of sea snakes from Australia's Gulf of Carpentaria first described for the scientific literature in 2012. It is a yellow to brown, striped snake that reaches up to a meter in length. It gives live birth and is venomous enough to be dangerous to humans. The primary distinguishing trait of the rough-scaled sea snake is the presence of a single spine on every scale covering the snake's body.
|
|
The snake's tough, spiny scales may protect it from being buffeted against the rocks of its stony estuary habitats by the action of the waves and currents. Other less spectacular traits distinguishing it from other members of the genus Hydrophis include the lack of a groove running through the scales underlying its abdomen, a larger and rounder skull, differing numbers of scales around the circumference of different bodily regions, and a larger number of stripes than many sea snakes have.

Thirty-three sea snakes from family Hydrophiidae inhabit Australia's northern waters; many are extremely venomous. Two species of sea snake from the Acrochordidae also occur in Australian waters. Australia has only 11 species from the world's most significant snake family Colubridae; none are endemic, and they are considered to be relatively recent arrivals from Asia. There are 15 python species and 45 species of insectivorous blind snake.Wilson and Swan (2017), p. 476 There are 30 species of goanna in Australia.

Being covered in scales largely precludes cutaneous respiration in reptiles, but gas exchange may occur between scales or areas with reduced scales. Some turtles rely on cutaneous respiration from around the cloaca during underwater hibernation. In some sea snakes, cutaneous respiration can account for up to 30 percent of total oxygen uptake and is important when diving, during which blood is shunted away from the lungs and towards capillaries in the skin, in some cases causing the skin to turn pink.

A hook-nosed sea snake seen on Arossim Beach, South Goa, India. This snake was found in a fishing net and later released to the sea. Enhydrina schistosa, commonly known as the beaked sea snake', ('), hook-nosed sea snake, common sea snake, or the Valakadyn sea snake, is a highly venomous species of sea snake common throughout the tropical Indo-Pacific. This species is implicated in more than 50% of all bites caused by sea snakes, as well as the majority of envenomings and fatalities.

Some species are also known to hold their elongated pectorals erect and forward, possibly providing a further means of detection. Halosaurs are benthic fish, spending their time cruising over or resting on the sea floor, where temperatures may be just 2-4 °C. They propel themselves with rhythmic, lateral undulations of their bodies, not unlike sea snakes. Halosaurs are thought to prey mainly on benthic invertebrates, such as polychaete worms, echinoderms, and crustaceans such as copepods, but they may also consume small fishes and cephalopods.

This ultimately led to an animal similar to today's sea snakes. In the Late Cretaceous, snakes recolonized land, and continued to diversify into today's snakes. Fossilized snake remains are known from early Late Cretaceous marine sediments, which is consistent with this hypothesis; particularly so, as they are older than the terrestrial Najash rionegrina. Similar skull structure, reduced or absent limbs, and other anatomical features found in both mosasaurs and snakes led to a positive cladistical correlation, and some of these features are shared with varanids.

Sea snakes (the Hydrophiinae), sometimes considered to be a separate family, have adapted to a marine way of life in different ways and to various degrees. All have evolved paddle-like tails for swimming and the ability to excrete salt. Most also have laterally compressed bodies, their ventral scales are much reduced in size, their nostrils are located dorsally (no internasal scales), and they give birth to live young (viviparity). The reduction in ventral scaling has greatly diminished their land mobility, but aids in swimming.

Like all "true" sea snakes, H. semperi is a rather heavyset snake, elongated with a small head. It possesses the characteristic flattened, paddle-like tail found in the members of its subfamily. This particular species is considered short in comparison to the rest of the family; adult specimens of H. semperi that have been caught have a total length (including tail) of . The snake is colored much like a typical sea snake, having a dark blue or black body with narrow yellow (sometimes white) crossbands.

A screenshot of the ZX Spectrum version of Thanatos The player character Thanatos has two resources: Flame and Heart. Flame is expended by breathing fire. This attack is required to burn down the gate of the castle and may be used to burn foreground objects such as rocks, knights, horses, soldiers and different dangerous creatures (such as other dragons, huge spiders, and giant sea snakes). Flame may be recovered by eating witches, who may be found tied between stakes, though a knight could still ambush nearby.
|
|
Heart is depleted as Thanatos is attacked by soldiers, knights, big creatures and rockfalls; this results in a quicker heartbeat and may finally cause an infarction. Heart is also spent when flying too fast for too long. Heart's level may be recovered by landing and walking slowly or staying still without being injured. Thanatos may also attack enemies by picking up an object in his claw and dropping them from a height; rocks and most enemies can be caught this way, even giant sea snakes.

Aipysurus laevis has been found to have photoreceptors in the skin of its tail, allowing it to detect light and presumably ensuring it is completely hidden, including its tail, inside coral holes during the day. While other species have not been tested, A. laevis possibly is not unique among sea snakes in this respect. Dermal light sensitivity is found in all the major animal phyla. Males can reach sexual maturity in their third year, while females do not until their fourth or fifth year.

The person was an 11-year-old boy, bitten two weeks earlier in Ecuador, but treated only with antibiotics. Some Australian elapids and most viper envenomations will cause coagulopathy, sometimes so severe that a person may bleed spontaneously from the mouth, nose, and even old, seemingly healed wounds. Internal organs may bleed, including the brain and intestines, and ecchymosis (bruising) of the skin is often seen. The venom of elapids, including sea snakes, kraits, cobras, king cobra, mambas, and many Australian species, contains toxins which attack the nervous system, causing neurotoxicity.

Living at the same time as, but not closely related to, dinosaurs, the mosasaurs resembled crocodiles but were more strongly adapted to marine life. They became extinct 66 million years ago, at the same time as the dinosaurs. Modern diapsids which have made their own adaptions to allow them to spend significant time in the water include marine iguanas and marine crocodiles. Sea snakes are extensively adapted to the marine environment, giving birth to live offspring in the same way as the Euryapsida (see below) and are largely incapable of terrestrial activity.

Eocene strata which exposed in the site and contains marine vertebrate fossils. (Gehannam Fm, Berket Qaroun Fm and Qasr El Sagha Fm.) Fossil reptiles are represented by fossils of crocodiles and sea turtles, and bones of sea snakes have also been recorded. There are many species of bony fish, sharks and rays represented, but most of the fossils are isolated small teeth and these are not often conspicuous. Larger fish fossils include the rostra and pegs of sawfish; a sawfish rostrum of 1.8 metres long is laid out in the park.

Asia has a rich reptile fauna. Earless monitor lizards, snakes of the families Uropeltidae, Acrochordidae and Xenopeltidae and gavials are endemic to Asia. Indian cobra Komodo dragon The crocodiles include mugger crocodile, gharial, false gharial and saltwater crocodile. The more common of the numerous snakes are pipe snakes (Melanophidium, Plectrurus, Rhinophis, Uropeltis), sea snakes, Elapids (king cobra, Bungarus, Calliophis, Naja, Walterinnesia), vipers (Azemiops, Daboia, Dendrelaphis, Echis, Hypnale, Protobothrops, Trimeresurus, Ovophis, Pseudocerastes, Gloydius etc.), colubrids (Achalinus, Amphiesma, Boiga, Calamaria, Cerberus, Coluber, Enhydris, Lycodon, Oligodon, Opisthotropis, Rhabdophis, Pareas, Psammophis, Ptyas, Sibynophis, Spalerosophis, Trachischium etc.) and blind snakes.

Most of the Pacific Islands are free of terrestrial snakes, although sea snakes are common in coral reefs. In the Oceanian realm, only Micronesia and Tonga, where at least 10 envenomations occur annually, face an appreciable burden of snakebite. In Australia, there are many more annual cases of spiderbite and jellyfish envenomation than snakebite; however, when considering the number of fatal cases, snakebite is the most serious type of envenoming. Australia is unique in that it is the only continent where venomous snakes constitute the majority of species.

Sometimes snakes have enlarged scales, either single or paired, under the tail; these are called subcaudals or urosteges. These subcaudals may be smooth or keeled as in Bitis arietans somalica. The end of the tail may simply taper into a tip (as in the case of most snakes), it may form a spine (as in Acanthophis), end in a bony spur (as in Lachesis), a rattle (as in Crotalus), or a rudder as seen in many sea snakes.

Marine reptiles are reptiles which have become secondarily adapted for an aquatic or semiaquatic life in a marine environment. Currently, of the approximately 12,000 extant reptile species and subspecies, only about 100 are classed as marine reptiles: extant marine reptiles include marine iguanas, sea snakes, sea turtles and saltwater crocodiles. The earliest marine reptiles arose in the Permian period during the Paleozoic era. During the Mesozoic era, many groups of reptiles became adapted to life in the seas, including such familiar clades as the ichthyosaurs, plesiosaurs, mosasaurs, nothosaurs, placodonts, sea turtles, thalattosaurs and thalattosuchians.

In more than a decade of local sea snake research only 9 rough-scaled sea snakes have ever been found. Meanwhile, the same researchers had encountered some 10,000 individuals of other sea snake species in the same time period. Even if a rough-scaled sea snake was nearby it would likely be difficult to see due to the low visibility of its murky habitat. The rough-scaled sea snake had managed to avoid being serendipitously discovered by local fishermen trawling for prawns the way many other sea snake species are commonly caught.

Their limb bones were reduced in length and their paddles were formed by webbing between their long finger and toe bones. Their tails were broad, and supplied their locomotive power. Until recently, mosasaurs were assumed to have swum in a method similar to the one used today by conger eels and sea snakes, undulating their entire bodies from side to side. However, new evidence suggests that many advanced mosasaurs had large, crescent-shaped flukes on the ends of their tails, similar to those of sharks and some ichthyosaurs.

They use ponds and marshes inside forests in both Africa and Asia, especially in south-east Asia where they use grassy and marshy areas in clearings in evergreen rainforests. In India, they are an uncommon species in coastal habitats. They use coastal areas in Africa also, with birds in Sulawasi observed to be eating sea snakes, and birds on the Kenya coast foraging in coral reefs and mudflats. In an agricultural landscape in north India, woolly-necked storks preferred fallow fields during the summer and monsoon seasons, and natural freshwater wetlands during the winter.

As a marine biologist, Rubinoff was influenced by Ernst Mayr's in the early 1960s regarding the evolution of fishes at the Isthmus of Panama. Mayr assigned Rubinoff to travel to Panama, to study the evolution of various genera of fish of the region. Rubinoff pioneered research regarding the effect of the Panama Canal on the ocean's ecology and the evolution of animals within it. He also helped discover that yellow-bellied sea snakes can control their buoyancy, which allows them to dive as deep as 50 metres and float at certain depths.

Depiction of baleen whaling, 1840 Stranded sperm whale engraving, 1598 Whalers from the 17th to 19th centuries depicted whales in drawings and recounted tales of their occupation. Although they knew that whales were harmless giants, they described battles with harpooned animals. These included descriptions of sea monsters, including huge whales, sharks, sea snakes, giant squid and octopuses. Among the first whalers who described their experiences on whaling trips was Captain William Scoresby from Great Britain, who published the book Northern Whale Fishery, describing the hunt for northern baleen whales.

While not extant today, the Madtsoiidae, a family of giant, primitive, python-like snakes, was around until 50,000 years ago in Australia, represented by genera such as Wonambi. There are numerous debates in the systematics within the group. For instance, many sources classify Boidae and Pythonidae as one family, while some keep the Elapidae and Hydrophiidae (sea snakes) separate for practical reasons despite their extremely close relation. Recent molecular studies support the monophyly of the clades of modern snakes, scolecophidians, typhlopids + anomalepidids, alethinophidians, core alethinophidians, uropeltids (Cylindrophis, Anomochilus, uropeltines), macrostomatans, booids, boids, pythonids and caenophidians.

Historically, the genus Chelonibia contained C. testudinaria, found growing only on sea turtles, and C. patula, a generalist found growing on a range of living hosts including decapods, gastropods, mantis shrimps and sea snakes, but very rarely on sea turtles. It was puzzling why a barnacle that was adaptable to such a broad range of hosts, should avoid the sea turtle. The two are distinguished morphologically as well as by host, and were thought to be different species. However, examination of the genetic differences between the pair showed that they are in fact con-specific.

Several palatable moths produce ultrasonic click calls to mimic unpalatable tiger moths. Octopuses of the genus Thaumoctopus (the mimic octopus) are able to intentionally alter their body shape and coloration to resemble dangerous sea snakes or lionfish. In the Amazon, the helmeted woodpecker (Dryocopus galeatus), a rare species which lives in the Atlantic Forest of Brazil, Paraguay, and Argentina, has a similar red crest, black back, and barred underside to two larger woodpeckers: Dryocopus lineatus and Campephilus robustus. This mimicry reduces attacks on Dryocopus galeatus from other animals.

Disteira was characterized by Boulenger in 1890 as having grooved maxillary teeth following the first pair of poison fangs. However, later dental examination under more powerful magnification found all sea snakes have grooves in their teeth, some deep and wide channels visible to the naked eye, others only at the base of the tooth and requiring magnification to observe. In light of those new findings, Disteira and Hydrophis were merged until McDowell resurrected Disteira as a separate genus in 1972 to accommodate new species. He redefined Disteira as possessing a broad dorsal portion of the venom gland muscle called the Oxyuranus pattern.

Since envenomation is completely voluntary, all venomous snakes are capable of biting without injecting venom into a person. Snakes may deliver such a "dry bite" rather than waste their venom on a creature too large for them to eat, a behaviour called venom metering. However, the percentage of dry bites varies among species: 80 percent of bites inflicted by sea snakes, which are normally timid, do not result in envenomation, whereas only 25 percent of pit viper bites are dry. Furthermore, some snake genera, such as rattlesnakes, significantly increase the amount of venom injected in defensive bites compared to predatory strikes.
|
|
These are cobra, krait, Russell's viper, sawscaled viper, green snakes, and sea snakes. However, most of the bites are reported by nonvenomous snakes and even as many as 40% bites inflicted by venomous snakes do not produce signs of envenoming. On the Indian subcontinent, almost all snakebite deaths have traditionally been attributed to the Big Four, consisting of the Russell's viper, Indian cobra, saw-scaled viper, and the common krait. However, studies have shown that the hump-nosed viper, previously considered essentially harmless and misidentified as the saw-scaled viper, is capable of delivering a fatal bite.

Species that are important to people as food, such as the golden mahseer and large freshwater shrimp (Macrobrachium species), are part of the abundant aquatic life. Along the shores of Astola and Ormara beaches of Balochistan and Hawk'e Bay and Sandspit beaches of Sindh are nesting sites for five endangered species of sea turtles: green sea, loggerhead, hawksbill, olive ridley and leatherback. Sea snakes such as yellow-bellied sea snake are also found in the pelagic zone of the sea. The wetlands of Pakistan are also a home to the endangered species of gharial and mugger crocodile who prefer freshwater habitat.

Reptiles Of the marine reptiles that live within the gulf, sea turtles are the most prominent with several species such as the Pacific Green Sea Turtle, Olive Ridley, Hawksbill, and Pacific Leatherback. The sea turtles in the area are drawn by the warm water temperature and the presence of jellyfish and marine plants which the sea turtles feed off of. Along with sea turtles; yellow bellied sea snakes, saltwater caimans, and saltwater crocodiles also inhabit the area. Sharks Several species of sharks live within the gulf; these species include the Whale Shark, Scalloped Hammer-Head, and Rays.

Marine turtles are common in the Park, with green turtle (Chelonia mydas), loggerhead turtle (Caretta caretta), hawksbill turtle (Eretmochelys imbricata) and occasional sightings of leatherback turtles. Nesting green turtles and loggerhead turtles have been recorded on several beaches, with some eggs hatching successfully. Only a few species of sea snakes have been recorded in the region, including the Elegant sea snake (Hydrophis elegans) and Yellow-bellied sea snake (Pelamis platurus). The only reptile recorded on Muttonbird Island since 1969 is Burton’s Snake Lizard (Lialis burtonis) though Eastern Water Dragons (Physignathus lesueurii) were plentiful prior to 1930.

The zebra shark feeds primarily on shelled molluscs, though it also takes crustaceans, small bony fishes, and possibly sea snakes. The slender, flexible body of this shark allows it to wriggle into narrow holes and crevices in search of food, while its small mouth and thickly muscled buccal cavity allow it to create a powerful suction force with which to extract prey. This species is large and has no confirmed predators, but hatchlings may be preyed upon by larger fishes and marine mammals. Known parasites of the zebra shark include four species of tapeworms in the genus Pedibothrium.

Of the snakes the ‘Guardian’ commands, vipers and cobras are the most famous among them, but you should fear the banded sea krait or yellow-lipped sea krait (Laticauda colubrine) the most, because one drop of its venom can kill three adults and there is no antidote. They are commonly found in rivers in rainforests as well as tropical coasts. Sea snakes are trapped in the fishing nets occasionally. When an unfortunate fisherman is busy sorting out the fishes, he might be bitten by sea snake without knowing it, due to the anesthetic effect of the venom.

The water monitor can grow to at least in length and and can move quickly. The rich coral reefs around the coast, particularly around popular diving spots such as Tulamben, Amed, Menjangan or neighbouring Nusa Penida, host a wide range of marine life, for instance hawksbill turtle, giant sunfish, giant manta ray, giant moray eel, bumphead parrotfish, hammerhead shark, reef shark, barracuda, and sea snakes. Dolphins are commonly encountered on the north coast near Singaraja and Lovina. A team of scientists conducted a survey from 29 April 2011 to 11 May 2011 at 33 sea sites around Bali.

The effect of the venom of proteroglyphous snakes (sea snakes, kraits, mambas, black snakes, tiger snakes, and death adders) is mainly on the nervous system, respiratory paralysis being quickly produced by bringing the venom into contact with the central nervous mechanism that controls respiration; the pain and local swelling that follow a bite are not usually severe. The bite of all the proteroglyphous elapids, even of the smallest and gentlest, such as the coral snakes, is, so far as known, deadly to humans. However, some mildly venomous elapids remain, such as the hooded snakes (Parasuta), bandy-bandies (Vermicella), etc.

The island Île des Pins is home to the crested gecko Correlophus ciliatus and the world's largest gecko Rhacodactylus leachianus. The island of Grande Terre has the greatest variety of reptiles, giant gecko, (Rhacodactylus leachianus) is present too, and the giant skink (Phoboscincus bocourti).. The local sea snakes laticaudinae have venom ten times as potent as rattlesnake venom. Before the arrival of Europeans, the only mammals in the island were six endemic bat species, including Rousettus, a large fruit bat that was eaten by locals. The world's highest biodiversity of Volutomitridae is in waters off New Caledonia.

Entering the cave of Gato Island can always be done with any outrigger boat. Everybody is allowed to enter the cave for diving and dock their boat inside or outside the opening of the cave. However, during high tide, it could be very difficult to come in due to the small opening that would make boat maneuverability troublesome. Once docked inside, divers are enjoined to do their diving activities with their diving instructors, dive masters or buddy, and those who cannot can do snorkeling but should take precaution since the island is haven for the yellow-lipped sea krait or locally known as "balingkasaw", a species of venomous sea snakes.

They are similar to the yōkai called isoonna of Kyushu, and like the isoonna, they are said to appear at seas or rivers. Their name comes from how their hair is always set in legends. They are also theorized to be the changed form of sea snakes. Many Edo Period publications such as the Hyakkai Zukan, Gazu Hyakki Yagyō, among others, depict this yōkai as a woman with a snake body, which would make it appear as if this was a well-known yōkai of the time, but there are no stories about a snake-bodied nure-onna in the classical literature of the time that can be found.

Most diving vertebrates make relatively short shallow dives. Sea snakes, crocodiles and marine iguanas only dive in inshore waters and seldom dive deeper than 10 m. Some of these groups can make much deeper and longer dives. Emperor penguins regularly dive to depths of 400 to 500 m for 4 to 5 minutes, often dive for 8 to 12 minutes and have a maximum endurance of about 22 minutes. Elephant seals stay at sea for between 2 and 8 months and dive continuously, spending 90% of their time underwater and averaging 20 minutes per dive with less than 3 minutes at the surface between dives.

A 2015 study concluded that locomotion was mostly done by the fore-flippers while the hind-flippers functioned in maneuverability and stability; a 2017 study concluded that the hind-flippers of plesiosaurs produced 60% more thrust and had 40% more efficiency when moving in harmony with the fore-flippers. The paddles of plesiosaurs were so rigid and specialized for swimming that they could not have come on land to lay eggs like sea turtles. Therefore, they probably gave live-birth (viviparity) to their young like sea snakes. Evidence for live- birth in plesiosaurs is provided by the fossil of an adult Polycotylus with a single fetus inside.

This was followed by extensive studies on sea snakes, marine turtles, bats, and other small mammals and studies on herpetofauna, biogeography, resource use, land use, rain-water harvesting and coral reef socioeconomics, in addition to protected area management planning, ecologically suitable management planning. The entrance to the Crocodile Bank The bank was started with only 30 mugger adults, which grew to 8,000 by the 1990s. Although the breeding program was a great success and many crocodiles were initially released back into the wild, this practice has essentially stopped now due to the loss of habitat. By 2010, there were 14 species of crocodilians at the bank.

Calotes versicolorSince the islands are very small, land-based reptiles are rare. There is a species of gecko, as well as one species of agamid lizard, Calotes versicolor,Bluepeace, Environment News, Articles and Reports, 2007 the skink Lygosoma albopunctatum, the wolf snake Lycodon aulicus and a small harmless blind snake Ramphotyphlops braminus. In the sea there are turtles, like the green turtle, the hawksbill turtle and the leatherback turtle, that lay eggs on Maldivian beaches. Pelagic sea snakes (Hydrophis platurus) that live in the Indian Ocean are occasionally cast up onto the shore after storms, where they are rendered helpless and unable to return to the sea.

It is home to many species of seabirds and some animals flit in and out of the caves in the sea. The island is constantly washed by strong currents thus creating side cuttings with high wall of rock faces. There is an underwater cave where divers encounter poisonous sea snakes, colored fishes and some species of shark believed to be sleeping during the day, which can be seen about 30 meters deep on the ground of the sea. The view inside and under the water cave is magnificent and divers would often liken it as if you are looking to a glass stained window with sparkling blue color and the glowing water from the sunlight.

The Torah does not classify animals under modern scientific categories of mammals, fish, reptiles and birds. Rather, the religious categories are land-dwelling animals (land mammals, flightless birds, and land reptiles, etc.), flying animals (birds, insects, flying mammals such as bats), and water-bound animals (fish, mammals such as whales, reptiles such as sea snakes, crustaceans, mollouscs, etc.). Given that each of these religious categories of animals includes species of at least two or more of each scientific categories of animals, there is no general kashrut rules relating per se to mammals, birds, reptiles, or fish. However, rules for each of these class of animals can be extrapolated from the biblical requirements.

Nearly all venomous species in Australia are elapids, as vipers are absent from the continent. The brown snakes, death adders, mulga snakes, taipans, and tiger snakes are the five groups that inflict virtually all reported snakebites, although copperheads, rough-scaled snakes, and members of the genus Hoplocephalus are also occasionally involved in bites. Of the five dangerous groups, the highly venomous eastern brown snake, which is widespread and common in both rural and urban environments, is the most important—it is estimated to be responsible for up to 60% of all deaths caused by snakebite. In Northern Australia, sea snakes are common and occasionally inflict bites, although far less frequently than terrestrial snakes.

The Shiva Purana says Nageshvara Jyotirlinga is in 'the Darukavana', which is an ancient name of a forest in India. 'Darukavana' finds mention in Indian epics, such as Kamyakavana, Dvaitavana, Dandakavana. A narrative in the Shiva Purana about the Nageshvara Jyotirlinga tells of a demon named Daruk, who attacked a Shiva devotee named Supriya and imprisoned him along with many others in his city of Darukavana, a city under the sea inhabited by sea snakes and demons. At the urgent exhortations of Supriya, the prisoners started to chant the holy mantra of Shiva and immediately thereafter Lord Shiva appeared and the demon was vanquished, later residing there in the form of a Jyotirlinga.

Diving weddell seals The physiology of underwater diving is the physiological adaptations to diving of air-breathing vertebrates that have returned to the ocean from terrestrial lineages. They are a diverse group that include sea snakes, sea turtles, the marine iguana, saltwater crocodiles, penguins, pinnipeds, cetaceans, sea otters, manatees and dugongs. All known diving vertebrates dive to feed, and the extent of the diving in terms of depth and duration are influenced by feeding strategies, but also, in some cases, with predator avoidance. Diving behaviour is inextricably linked with the physiological adaptations for diving and often the behaviour leads to investigation of the physiology that makes the behaviour possible, so they are considered together where possible.

The white-bellied sea eagle may also dive at a 45-degree angle from its perch and briefly submerge to catch fish near the water surface. While hunting over water on sunny days, it often flies directly into the sun or at right angles to it, seemingly to avoid casting shadows over the water and hence alerting potential prey. Seizing waterborne prey The white-bellied sea eagle hunts mainly aquatic animals, such as fish, turtles and sea snakes, but it takes birds, such as little penguins, Eurasian coots and shearwaters, and mammals (including flying foxes) as well. In the Bismarck Archipelago it has been reported feeding on two species of possum, the northern common cuscus and common spotted cuscus.

A captive breeding programme is being undertaken at Taiz Zoo in the Yemeni highlands. Other mammals found in Yemen include the mountain gazelle, gray wolf, Blanford's fox, Rüppell's fox, caracal, sand cat, wildcat, common genet, striped hyena, golden jackal, honey badger, bushy- tailed mongoose, rock hyrax, desert hedgehog, Arabian shrew, golden spiny mouse, lesser Egyptian jerboa, several species of gerbils, king jird, Yemeni mouse and a number of species of bat. Snakes found in Yemen include the Egyptian cobra, the horned viper and the puff adder, as well as several species of sea snakes. There is an endemic monitor lizard (Varanus yemensis), numerous species of lizard, several geckos and the veiled chameleon.

Conchoderma virgatum is found attached to a wider range of floating objects and nekton than goose barnacles in the genus Lepas. This species seems to have evolved from the same common ancestry as Conchoderma auritum, which occurs on whales, and Alepas which occur on jellyfish. Most attachments are to inanimate objects such as buoys and the hulls of ships, but it has been recorded as being attached to seaweed, crabs, sea snakes, turtles and whales, and at least thirteen species of fish. Direct attachment to fish is infrequent, perhaps because of the mucus produced by the skin; in one example, four of the barnacles were attached to a single spine of a spot-fin porcupinefish (Diodon hystrix).

From the same book, a certain character said, "in the sea of Hachijō, Zushū (now Hachijō-jima, Tokyo, there are what one might think are small eel, but it is actually an eel-like creature that goes around in a loop, and since it moves without eyes or a mouth, so when it gets caught on the bow of a ship, it is not moving by extending itself, but rather revolving around". In the entry "ayakashi" in Toriyama Sekien's Konjaku Hyakki Shūi, there is a drawing of a large sea snake, but it was drawn as ikuchi, an ayakashi (strange phenomenon of the sea). During the present Heisei period, there have been hypotheses proposed that they are not strange fish, but rather giant sea snakes, or that they are humans who have drowned and want others to join them. Sekien's yōkai drawing resemble a sea serpent, a cryptid, some have identified them to be the same.

However, larger animals are taken only sporadically due to the fact only large males typically attack very large prey and large ungulates and other sizeable wild mammals are only sparsely distributed in this species' range, outside of a few key areas such as the Sundarbans. Off-setting this, goats, water buffalo and wild boar/pigs have been introduced to many of the areas occupied by saltwater crocodiles and returned to feral states to varying degrees and thus can amply support large crocodiles. Any type of domestic livestock, such as chicken (Gallus gallus domesticus), sheep (Ovis aries), pigs, horses (Equus ferus caballus) and cattle (Bos primigenius taurus), and domesticated animals/pets may be eaten if given the opportunity. As a seagoing species, the saltwater crocodile also preys on a variety of saltwater bony fish and other marine animals, including sea snakes, sea turtles, sea birds, dugongs (Dugong dugon), rays (including large sawfish), and small sharks.

Coral reefs form some of the world's most productive ecosystems, providing complex and varied marine habitats that support a wide range of other organisms. Fringing reefs just below low tide level have a mutually beneficial relationship with mangrove forests at high tide level and sea grass meadows in between: the reefs protect the mangroves and seagrass from strong currents and waves that would damage them or erode the sediments in which they are rooted, while the mangroves and sea grass protect the coral from large influxes of silt, fresh water and pollutants. This level of variety in the environment benefits many coral reef animals, which, for example, may feed in the sea grass and use the reefs for protection or breeding. Reefs are home to a variety of animals, including fish, seabirds, sponges, cnidarians (which includes some types of corals and jellyfish), worms, crustaceans (including shrimp, cleaner shrimp, spiny lobsters and crabs), mollusks (including cephalopods), echinoderms (including starfish, sea urchins and sea cucumbers), sea squirts, sea turtles and sea snakes.

Within a short span of time, the reef became home to a diverse aquatic life. There is a vast range of corals and fishes like groupers, lion fish, kingfish, eagle and manta rays, moray eels, sea snakes, triggerfish, parrot fish, angelfish, bannerfish, butterflyfish and crustaceans. Overall there has been 75 + different species recorded in this site. Some other marine life are: Malabar Grouper, Red Snapper, Blue line Grouper, Coral Banded Shrimp, Dancing Durban Shrimp, Spearing Mantis Shrimp, Humphead Batfish, Roundface Batfish, Zebra Batfish, Chevron Barracuda, Yellowtail Barracuda, Yellow Boxfish, Blue Spot Toby, Titan Triggerfish, Indian Vagabond Butterfly fish, Harlequin Sweetlips, Longfin Bannerfish, Blue tang surgeonfish Bronzelined Rabbitfish, Eyestripe Surgeonfish, Gold-lined spinefoot, Cleaner wrasse, Three spot Dascyllus, Blue ring angel fish, Yellowtail Chromis, Sargent fish, Copper Sweepers, Ring tailed Cardinalfish, Brown Lionfish, Chinese Trumpetfish, Salmacis Belli, Honeycomb Moray Eel, Moray Eels, Garden Eels, Porcupine Puffer fish, Blackspotted pufferfish, Peacock sole, Yellowspot Goatfish, Jackfish, Mackerels, Valenciennea Goby, Amblyeleotris Goby, Yellow Prawn Goby, Red Lionfish, Clearfin Lionfish, Pterois mombasae Lionfish.
