Sea sponges should be cultured at a salinity of 35ppt (salinity of seawater). Hypersalinity (high salt concentrations) in the immediate environment surrounding a sponge will dehydrate sponge cells, whereas a hyposaline (low salt concentration) environment dilutes the intracellular environment of the sponge. The pH of water must match that of seawater (pH 7.8–8.4) in order for sponge production to be maximized. Sponges are sensitive to temperature, and extreme fluctuations in ambient temperature can negatively affect the health of sea sponges.

More than 8000 species of sea sponges live in oceanic and freshwater habitats. Sponge fishing historically has been an important and lucrative industry, with yearly catches from years 1913 to 1938 regularly exceeding 181 tonnes and generating over 1 million U.S. dollars. However, this demand for sea sponges has seen catch rates peak and in 2003 the demand for bath sponges was 2,127 tonnes, with global production from harvesting only meeting a quarter of that amount. Early aquaculture research into optimising techniques for sea sponge aquaculture used a number of farming methods.

Hawksbill sea turtle, a spongivore A spongivore is an animal anatomically and physiologically adapted to eating animals of the phylum Porifera, commonly called sea sponges, for the main component of its diet. As a result of their diet, spongivore animals like the hawksbill turtle have developed sharp, narrow bird-like beak that allows them to reach within crevices on the reef to obtain sponges.
|
|
High temperatures lead to crashes in sponge cultures. Symbiotic bacteria that normally inhabit sea sponges start reproducing at an unsustainable rate when ambient temperature of the water increases by a few degrees. These bacteria then attack and destroy the sponge cells and tissue. It has been suggested that sponges should be cultured at water temperatures slightly below the ambient water temperature in the region the sponge has been originally isolated from.

Alfred Beyfus had another child from a previous relationship who was named Alfred Butt (1878–1962). Butt began his career as a clerk at the department store Harrods, where his uncle, Edgar Israel Cohen, was a director. Cohen, who had married Solomon's daughter Ada in 1876, came from a family of East End merchants dealing in sea sponges and cigars. In the 1890s Cohen left the family business and moved into retail, becoming a director of D.H.Evans and Harrods.

E. imbricata in a coral reef in alt=Photo of swimming turtle with extended head While they are omnivorous, sea sponges are their principal food; they constitute 70–95% of the turtles' diets. However, like many spongivores, they feed only on select species, ignoring many others. Caribbean populations feed primarily on the orders Astrophorida, Spirophorida, and Hadromerida in the class Demospongiae. Aside from sponges, hawksbills feed on algae, cnidarians, comb jellies and other jellyfish, and sea anemones.

Despite its prevalence in the environment, aluminium salts are not known to be used by any form of life. In keeping with its pervasiveness, it is well tolerated by plants and animals. Because of their prevalence, potential beneficial (or otherwise) biological roles of aluminium compounds are of continuing interest. Silicon is an essential element in biology, although only tiny traces of it appear to be required by animals, though various sea sponges need silicon in order to have structure.

However, researchers do not recommend using sea sponges as tampons, as they may contain dirt and microorganisms, especially if poorly sanitized. In the New Testament, a Roman soldier offers Jesus Christ a sponge soaked in vinegar on the tip of his spear (some versions say staff) for Jesus to drink during his crucifixion, as an act of mockery. Synthetic sponges were made possible to be manufactured only after the invention of polyester in 1941 and the commercial production of polyurethane foam in 1952.

Global fluorochemical sales amount to more than US$15 billion a year. Fluorocarbon gases are generally greenhouse gases with global-warming potentials 100 to 23,500 times that of carbon dioxide, SF6 having the highest global warming potential of any known substance. Organofluorine compounds often persist in the environment due to the strength of the carbon–fluorine bond. Fluorine has no known metabolic role in mammals; a few plants and sea sponges synthesize organofluorine poisons (most often monofluoroacetates) that help deter predation.

Sea sponge from Krapanj Krapanj has a rich history in deep sea diving, primarily in the harvesting and selling of sea sponges. Antun from Crete introduced Krapanj's inhabitants to diving and sea sponge gathering/processing over 300 years ago. For many years, diving for sponges had been the major income for Krapanj families, earning them the title of "Spužvari" (sponge vendors). By the middle of the 20th century the industry peaked with the inception of breathing apparatus and motorised boats.

In 1872, he took part in the "Pomerania" expedition to the North Sea. For several years during the 1890s, he was president of the German Zoological Society (Deutsche Zoologische Gesellschaft). He made contributions in his studies on the anatomy and developmental history of invertebrates, in particular, his research and publications in regards to sea-sponges. He was especially interested in a class of sponges known as Hexactinellida, of which he studied from collections taken from the U.S. "Albatross Expedition" and the British "Challenger Expedition" (1873–76).

In addition, these spicules have built-in lenses in the ends which gather and focus light in dark conditions. It has been theorized that this ability may function as a light source for symbiotic algae (as with Rosella racovitzae) or as an attractor for shrimp which live inside the Venus' Flower Basket. However, a conclusive decision has not been reached; it may be that the light capabilities are simply a coincidental trait from a purely structural element. Spicules funnel light deep inside sea sponges.

This system was later altered in 1991 to record trawl trips and other cruising information. GFCATCH has also added records of the station's cruising and trawling activities as well as shipping patterns since 1954. This data is gathered from both official ship logs and first-hand accounts from the crews and fishery scientists that attended those voyages. The database also keeps a catalog of the species that were studied on each expedition, ranging from sea sponges and jelly fish to various arthropods, like shrimp.

The side of a tide pool showing sea stars (Dermasterias), sea anemones (Anthopleura) and sea sponges in Santa Cruz, California. Biotic communities vary in size, and larger ones may contain smaller ones. Species interactions are evident in food or feeding relationships. A method of delineating biotic communities is to map the food network to identify which species feed upon which others and then determine the system boundary as the one that can be drawn through the fewest consumption links relative to the number of species within the boundary.

The area supports cold water coral colonies and carbonate mound fields such as the Logachev Mounds; the trough supports a rich deep sea fish population. There are also unusual aggregations of deep-sea sponges, in particular the encrusting sponge and bird’s nest sponge. A range of other species are found amongst the sponges beds, which are considered biodiversity hotspots. For the bird’s nest sponge associated species include ascidians, Foraminifera, polychaetes and burrowing anemones, whilst for the encrusting sponge beds species such as anemones, ascidians, crinoids and ophiuroids are found.

The parish also contains several Victorian gardens, now open to the public: Glendurgan, Trebah, Carwinion,Carwinion and Penjerrick. The coastline and cliffs south-east of the church town from Toll Point to Rosemullion Head forms the Rosemullion SSSI (Site of Special Scientific Interest), noted for its geological and biological interest. Marine species found here include Mytilus mussels, various seaweeds and sea sponges, such as Botryllus schlosseri.

Research on the Euplectella aspergillum (Venus' Flower Basket) demonstrated that the spicules of certain deep-sea sponges have similar traits to Optical fibre. In addition to being able to trap and transport light, these spicules have a number of advantages over commercial fibre optic wire. They are stronger, resist stress easier, and form their own support elements. Also, the low-temperature formation of the spicules, as compared to the high temperature stretching process of commercial fibre optics, allows for the addition of impurities which improve the refractive index.

Haematopodin is the more stable breakdown product of Haematopodin B. Both compounds are found in the mushroom Mycena haematopus, although haematopodin only occurs in trace amounts in fresh fruit bodies. Similar pigments (with the 1,3,4,5-tetrahydropyrrolo[4,3,2-de]quinoline structure), known as batzellins and damirones, have been found in sea sponges. A chemical synthesis for haematopodin was reported in 1996. Key steps in the synthesis involved the addition of 3-[(2,4-dimethoxybenzyl)amino]-1-propanol to the indolo-6,7-quinone and cyclization of the resulting adduct with trifluoroacetic acid.

For dolphins particularly, the largest non-genetic effects on their evolution are due to culture and social structure. Based on a 2014 study, the population of Indo-Pacific bottlenose dolphins (Tursiops sp.) around Shark Bay of Western Australia can be divided into spongers and nonspongers. Spongers put sea sponges on their snout as a protective means against abrasions from sharp objects, stingray barbs, or toxic organisms. The sponges also help the dolphins target fish without swim bladders, since echolocation cannot detect these fish easily against a complex background.

Cladorhizidae is a family of demosponges which are carnivorous and prey on crustaceans and other small animals. They are deep sea sponges typically found on oceanic ridges and seamount systems. As of 2017, nine new species have been discovered in the Southwest Indian Ocean Ridge (SWIOR) including: Abyssocladia boletiphora, Ab. corniculiphora, Ab. hemiradiata, Asbestopluma (Asbestopluma) unguiferata, As. (A.) jamescooki, As. (A.) laminachela, As. (A.) pseudoisochela, As. (A.) ramuscula and Chondrocladia (Meliiderma) rogersi. These discoveries have proven to show that this family of unique sponges is much more diverse than originally known.

The Shell corporation uses a proprietary process for the synthesis of 1-pentadecanol (referring to it by the trade name Neodol 5) via hydroformylation of olefins produced from ethylene. Like other long-chain primary alcohols, it is used as an ingredient in industrial chemicals, lubricating oils, and consumer products such as lotions and creams. Additionally, it can be used as a feedstock for processes that use ethoxylation and sulfation reactions to produce surfactants. In 2008, a synthesis of pachastrissamine (a cytotoxic lipid compound found in sea sponges) was described starting from 1-pentadecanol.

Sea sponge aquaculture is the process of farming sea sponges under controlled conditions. It has been conducted in the world's oceans for centuries using a number of aquaculture techniques. There are many factors such as light, salinity, pH, dissolved oxygen and the accumulation of waste products that influence the growth rate of sponges. The benefits of sea sponge aquaculture are realised as a result of its ease of establishment, minimum infrastructure requirements and the potential to be used as a source of income for populations living in developing countries.

With a slight 1920s influence, design details included drop-waists, pearl belts, seaweed panniers, boxy tweed jackets, and ruffles that mimicked sea sponges. There were also aquatic-themed accessories with handbags, shoes, and jewelry shaped as seashells, conch shells, and coral. The production included stylized, oversized installations of giant sea life sculptures: stingray, sea horse, shark, anemone, and coral branches in a variety of matte, glossy, and sparkly finishes. Florence Welch provided the soundtrack with a live performance of "What the Water Gave Me." Saskia de Brauw opened the runway show.

Carl Linnaeus divided these animals into only two groups, the Insecta and the now-obsolete Vermes (worms). Jean- Baptiste Lamarck, who was appointed to the position of "Curator of Insecta and Vermes" at the Muséum National d'Histoire Naturelle in 1793, both coined the term "invertebrate" to describe such animals and divided the original two groups into ten, by splitting Arachnida and Crustacea from the Linnean Insecta, and Mollusca, Annelida, Cirripedia, Radiata, Coelenterata and Infusoria from the Linnean Vermes. They are now classified into over 30 phyla, from simple organisms such as sea sponges and flatworms to complex animals such as arthropods and molluscs.

What little energy is available in the bathypelagic zone filters from above in the form of detritus, faecal material, and the occasional invertebrate or mesopelagic fish. About 20% of the food that has its origins in the epipelagic zone falls down to the mesopelagic zone, but only about 5% filters down to the bathypelagic zone. The fish that do live there may have reduced or completely lost their gills, kidneys, hearts, and swimbladders, have slimy instead of scaly skin, and have a weak skeletal and muscular build. Most of the animals that live in the bathyl zone are invertebrates such as sea sponges, cephalopods, and echinoderms.

Bertarelli, 132 On the island there was also a flourishing production of charcoal (much sought after in Alexandria, where it was used for narghile).Bertarelli, 132 The fishing industry—mainly sea sponges—was important too.Bertarelli, 132 At the dawn of the 20th century the decay of the island's economy set in, accelerated by the decline of the Ottoman Empire and the population exchange between Greece and Turkey in 1923. In the late 1920s the island's population dropped to 3,000, while about 8,000 inhabitants lived abroad, predominantly in Australia, Egypt, Greece and the U.S.Bertarelli, 132 At that time the town had 730 inhabited houses, while 675 were already empty, and many ruined.

The land masses remained connected until between 450,000 and 180,000 years ago when at least two catastrophic glacial lake outburst floods breached the anticline and destroyed the ridge that connected Britain to Europe. A land connection across the southern North Sea existed intermittently at later times when periods of glaciation resulted in lower sea levels. At the end of the last glacial period, around 10,000 years ago, rising sea levels finally severed the last land connection. The cliffs' chalk face shows horizontal bands of dark-coloured flint which is composed of the remains of sea sponges and siliceous planktonic micro-organisms that hardened into the microscopic quartz crystals.

Baerida is an order of sea sponges in the subclass of Calcaronea, first described in 2000 by Radovan Borojevic, Nicole Boury-Esnault and Jean Vacelet. Species of the order Baerida are leuconoid calcareous sponges with the skeleton either composed exclusively of micro-diactines, or in which microdiactines constitute exclusively or predominantly a specific sector of the skeleton, such as choano-skeleton or atrial skeleton. Large or giant spicules are frequently present in the cortical skeleton, from which they can partially or fully invade the choanoderm. In sponges with a reinforced cortex, the inhalant pores can be restricted to a sieve-like ostia-bearing region.

The seamount of the Hebrides Terrace is thought to represent the remnant of an ancient volcano that rises to a height of almost 1 km above the surrounding seabed. It lies to the west of the Barra Fan, and supports a diverse range of marine life, including cold-water corals and deep sea sponges. The effect the seamount has on underwater currents is thought to ensure a good supply of food for many species of fish in the area, and the seamount is particularly associated with the orange roughy, a large long-living deep-sea fish. Several species of whale and shark also visit the area.

The episode "Teenage Mutant Leela's Hurdles" indicates that young Decapodians progress through various larval forms, including those resembling crustaceans, invertebrate, fish, coral, starfish, sea sponges, and clams, before reaching their humanoid adult forms. However, in the episode "A Taste of Freedom", a young Zoidberg is seen with his typical humanoid form. Dr. Zoidberg is also a skilled theremin player, and is the only person ever seen in the series to be 'good' enough to receive a present from Robot Santa. He is an honorary member of the Harlem Globetrotters, and a talented hand-to-claw combatant; he severs Fry's arm in an honor-duel ("Claw-Plach") and eventually fights and defeats the dangerous robot Clamps.

In preparation for labor, the woman was advised to bathe in wine and sweet-water baths to calm her mind before delivery. Her belly was then rubbed with oils to decrease the appearance of stretch marks, and her genitals were anointed with herbs and injected with softeners such as goose fat. The role of the midwife was very important during the process of childbirth and Soranus described her role in great detail. For example, the midwife was to have certain tools to ensure a safe delivery, including: clean olive oil, sea sponges, pieces of wool bandages to cradle the infant, a pillow, strong smelling herbs in case of fainting, and a birthing stool.

Bath sponges are currently being produced using the sponge Coscinoderma matthewsi with production of about 12,000 sponges, sold locally to residents and tourists in Pohnpei, Federated States of Micronesia. These sponges are one of the only true sustainably farmed sea sponges in the world. The sponges are farmed via the rope method, with low investment costs of a few thousand dollars for farming and maintenance equipment, producing 100% natural sponges with no harsh chemicals added during processing. Aquaculture production of C. matthewsi sponges was undertaken by the Marine and Environmental Research Institute of Pohnpei (MERIP), to try and generate a sustainable income for local community residents with few options to earn money.

Weedon, in collaboration with L. M. Jackman, was the first to use nuclear magnetic resonance spectroscopy to study the structures of carotenoids. He also worked on the synthesis of carotenoids and in 1953 described the synthesis of methylbixin which was produced by exposing bixin from Bixa orellana to iodine; later he successfully synthesised bixin using the Wittig reaction. During the 1960s and 1970s, Weedon's research group elucidated the structures of and synthesised a wide range of naturally occurring carotenoids. These included, canthaxanthin (responsible for the pink colour of flamingos), astaxanthin (responsible for the colour of lobsters), capsanthin and capsorubin (found in red peppers), renieratene (from Japanese sea sponges) and fucoxanthin (the most abundant carotenoid found in seaweed).

Thus waste generating (fed organisms) such as fish and shrimp are coupled with extractive organisms such as abalone, sponges or sea urchins, as a mechanism of removing excess nutrient matter from the water column. Sea sponges have a distinct advantage as an extractive organism in an integrated multi-trophic aquaculture system, as they have the potential of acting as a bioremediator to remove both pathogenic bacteria and organic matter. The sponge Hymeniacidon perlevis has exhibited an excellent ability to remove total organic carbon (TOC) from seawater under integrated aquaculture conditions, and could be a potentially useful bioremediation tool for aquaculture systems in regions where water pollution is high. Furthermore, the organic enrichment originating from fish farmed in the vicinity may stimulate sponge growth, resulting in more efficient sea sponge aquaculture.
