Description and characteristics
Species in this genus have developed webbed swimming structures at the front and back of their bodies which enable them to swim up off the surface of the sea floor and to journey as much as 1000m up into the water column. This is thought to help the animals move to new feeding grounds and avoid predators.
Many species have been described in this genus, however they are now belived to be all synonyms of E. eximia :
- Enypniastes eximia Théel, 1882 -- Pink swimming sea cucumber (only confirmed species to date)
- Enypniastes atlanticus (Heding, 1940)
- Enypniastes diaphana (Gilchrist, 1920)
- Enypniastes ecalcarea (Sluiter, 1901)
- Enypniastes obscura (Koehler & Vaney, 1905)
