Elpidiidae
Elpidiidae is a family of deep-sea sea cucumbers. They have a translucent body with long and stout podia acting like legs. The mouth is surrounded by thick and short oral tentacles, and the dorsal part often shows pairs of elongated podia as well, pointing upwards. Some species can also show swimming appendages on top of the mouth. Sea pigs live in the darkest parts of the ocean. When introduced to warm waters, their bodies disintegrate, making them vulnerable to sudden heat changes. Genera The following genera are recognised in the family Elpidiidae: *'' Achlyonice'' Théel, 1879 *'' Amperima'' Pawson, 1965 *'' Ellipinion'' Hérouard, 1923 *'' Elpidia'' Théel, 1876 *'' Irpa'' Danielssen & Koren, 1878 *''Kolga'' Danielssen & Koren, 1879 *'' Peniagone'' Théel, 1882 *'' Penilpidia'' Gebruk, 1988 *'' Protelpidia'' Gebruk, 1983 *'' Psychrelpidia'' Hérouard, 1923 *'' Psychroplanes'' Gebruk, 1988 *'' Rhipidothuria'' Hérouard, 1901 *''Scotoplanes'' Théel, 1882 Image:Unidentifi ...

Scotoplanes
''Scotoplanes'' is a genus of deep-sea sea cucumbers of the family Elpidiidae. Its species are commonly known as sea pigs. Locomotion Members of the Elpidiidae have particularly enlarged tube "feet" that have taken on a leg-like appearance, using water cavities within the skin to inflate and deflate thereby causing the appendages to move. These appendages are different from the normal tube feet of the broader order of Elasipodida due the replacement of ampullae with dermal cavities to account for the larger size of the Elpidiidae tube feet. ''Scotoplanes'' move through the top layer of seafloor sediment and disrupt both the surface and the resident infauna as it feeds. This type of movement is thought to be an adaptation to life on the soft floor of the deep-sea. These creatures, however, are able to swim when disturbed. Some species of ''Scotoplanes'' are benthopelagic and spend plenty of time in the water column. A frontal lobe as well as two anal lobes propel the sea pig throu ...

Scotoplanes Globosa
''Scotoplanes globosa,'' commonly known as the sea pig, is a species of sea cucumber that lives in the deep sea. It was first described by Hjalmar Théel, a Swedish scientist. ''Scotoplanes globosa'', along with numerous other sea cucumbers were discovered by Théel during an expedition on between the years of 1873-1876. ''Scotoplanes globosa'' was officially described in 1882, 6 to 9 years after its first sighting. ''Scotoplanes globosa'' is most closely related to the genus '' Peniagone''. Ecology Congregations of smaller ''Scotoplanes globosa'' are often observed on the ocean floor in groups of 10 to 30. However, groups of ''Scotoplanes globosa'' have been observed to be as many as 600 individuals in one congregation. A congregation of ''Scotoplanes globos''a is called a "trawl". These groups of ''Scotoplanes globosa'' often appear to all be facing in one direction, into the ocean current. It is believed that this behavior aids ''S. globosa'' in the detection of the richest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Cucumber
Sea cucumbers are echinoderms from the class Holothuroidea (). They are marine animals with a leathery skin and an elongated body containing a single, branched gonad. Sea cucumbers are found on the sea floor worldwide. The number of holothurian () species worldwide is about 1,717, with the greatest number being in the Asia-Pacific region. Many of these are gathered for human consumption and some species are cultivated in aquaculture systems. The harvested product is variously referred to as '' trepang'', ''namako'', ''bêche-de-mer'', or ''balate''. Sea cucumbers serve a useful role in the marine ecosystem as they help recycle nutrients, breaking down detritus and other organic matter, after which bacteria can continue the decomposition process. Like all echinoderms, sea cucumbers have an endoskeleton just below the skin, calcified structures that are usually reduced to isolated microscopic ossicles (or sclerietes) joined by connective tissue. In some species these can sometim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elpidia Glacialis
''Elpidia glacialis'' is a species of sea cucumber in the family Elpidiidae. It is found at abyssal depths in the Arctic Ocean, the Barents Sea, the Kara Sea and the north Atlantic Ocean. It was first described in 1876 by the Swedish zoologist Johan Hjalmar Théel after he had collected specimens while accompanying the explorer Adolf Erik Nordenskiöld on an expedition attempting to find the Northeast Passage. Ecology In a study in the Greenland Sea, ''E. glacialis'' occurred on the lower slopes of the continental shelf at depths of about . Other organisms occupying the same habitat included the sea lily ''Bathycrinus sp.'', the sea spider '' Ascorhynchus abyssi'', the brachiopod '' Waldheimia cranium'' and the zoanthid ''Epizoanthus sp.'' The sea lily and the sea cucumber were the dominant species present, perhaps because echinoderms are able to adopt various foraging strategies to suit the availability of food supplies. In another study, in the central Arctic Ocean, it was fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
