Enypniastes is a genus of deep-sea sea cucumber.

Description and characteristics[edit]

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.[1]

When Oceaneering ROV pilots saw and photographed the creature at 2500m depth they named it “The Headless Chicken Fish.”[2]


Many species have been described in this genus, however they are now belived to be all synonyms of E. eximia[1] :
