by Enypniastes is a genus of deep-sea sea cucumber. It is monotypic, being represented by the single species Enypniastes eximia.
Due to its unique appearance, the species has been dubbed the headless chicken fish, headless chicken monster, and the Spanish dancer.
It is also known as the swimming sea cucumber, and some are called the pink see-through fantasia.
Species in this genus have developed webbed swimming fin like 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 1,000 m (3,300 ft) up into the water column.
Its most distinct feature is its coloring, which is dictated by size: small enypniastes are a bright pink, and larger individuals are a more reddish-brown color.
It is also semi-transparent, and its intestine can be seen through its body, especially after feeding.
The enypniastes have a round bulbous body, bifurcated tentacles, and a large anterior sail.
They can also be bioluminescent.
