Scotoplanes is a genus of deep-sea sea cucumbers of the family Elpidiidae. Its species are commonly known as sea pigs.
Locomotion[edit]
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.[3] The "horns" on its back are also actually legs. Scotoplanes move through the top layer of seafloor sediment and disrupt both the surface and the resident infauna as it feeds.[4]
Ecology[edit]
Scotoplanes live on deep ocean bottoms, specifically on the abyssal plain in the Atlantic, Pacific and Indian Oceans, typically at depths of over 1,200[5]–5,000 metres.[6] Some related species can be found in the Antarctic. Scotoplanes (and all deep-sea holothurians) are deposit feeders and obtain food by extracting organic particles from deep-sea mud. Scotoplanes globosa has been observed to demonstrate strong preferences for rich, organic food that has freshly fallen from the ocean's surface[7] and uses olfaction to locate preferred food sources such as whale corpses.[8] Scotoplanes, like many sea cucumbers, often occur in huge densities, sometimes numbering in the hundreds when observed. Early collections have recorded groups of up to 300-600 individuals. Sea pigs are also known to host different parasitic invertebrates, including gastropods (snails) and small tanaid crustaceans. [citation needed]
Scotoplanes, like other sea cucumbers, host parasitic and commensal organisms. For example, it provides a shelter to juvenile crabs, Neolithodes diomedeae. It is known that such relationship benefits the crabs because they can reduce risks of predation when they are under the shelter.[9]
