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. Species The following species are recognised in the genus ''Elpidia'': *''Elpidia adenensis'' Belyaev, 1971 *''Elpidia antarctica'' Belyaev, 1971 *''Elpidia atakama'' Belyaev, 1971 *''Elpidia belyaevi'' Rogacheva, 2007 *''Elpidia birsteini'' Belyaev, 1971 *''Elpidia chilensis'' Belyaev, 1971 *''Elpidia decapoda'' Belyaev, 1975 *''Elpidia echinata'' (R.

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 ...
