Elpidia Soyoae
''Elpidia'' is a genus of deep-sea sea cucumbers. Members are characterised by their rod-shaped spicules which each have two pairs of obliquely placed horizontal arms and two vertical apophyses. There is a high degree of endemism in this genus with different species occupying different deep sea basins or regions.

Elpidia Glacialis
''Elpidia glacialis'' is a species of Holothuroidea, sea cucumber in the Family (biology), 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 Bourgueticrinida, sea lily ''Bathycrinidae, Bathycrinus sp.'', the sea spider ''Ascorhynchus abyssi'', the brachiopod ''Waldheimia cranium'' and the Zoantharia, zoanthid ''Epizoanthus sp.'' The sea lily and the sea cucumber were the dominant species present, perhaps because echinoderms can adopt various foraging strategies to suit the availability of food s ...

Holothuroidea Genera
Sea cucumbers are echinoderms from the class Holothuroidea ( ). They are benthic marine animals found on the sea floor worldwide, and the number of known holothuroid species worldwide is about 1,786, with the greatest number being in the Asia–Pacific region. Sea cucumbers serve a useful role in the marine ecosystem as detritivores who help recycle nutrients, breaking down detritus and other organic matter, after which microbes can continue the decomposition process. Sea cucumbers have a leathery skin and an elongated body containing a single, branched gonad, are named for their overall resemblance to the fruit of the cucumber plant. Like all echinoderms, sea cucumbers have a calcified dermal endoskeleton, which is usually reduced to isolated microscopic ossicles (or sclerietes) joined by connective tissue. In some species these can sometimes be enlarged to flattened plates, forming an armoured cuticle. In some abyssal or pelagic species such as '' Pelagothuria natatrix'' (orde ...

Elpidia Minutissima
''Elpidia minutissima'' is a species of deep-sea swimming sea cucumber in the family Elpidiidae. It is a detritivore and is found in the northern Pacific Ocean. Description Specimens collected from the Aleutian Trench averaged in length and had three pairs of dorsal podia whereas specimens collected from Station M in the northeastern Pacific Ocean at a depth of about had four pairs, two pairs on the dorsal surface and two pairs on the ventral surface, the hindermost of the ventral podia being shorter than the others. At times of low abundance, the average length of these sea cucumbers was similar to the specimens from the Aleutian Trench but at times of high abundance it increased to . It is possible that these two populations are not in fact the same species. Ecology ''Elpidia minutissima'' feeds on detritus on the seabed, the result of "marine snow" consisting of mucus, faeces and organic debris, that sink into the depths from surface waters. It plays an important part in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
