Enypniastes
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.
Description
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 up into the water column. This is thought to help the animals move to new feeding grounds and avoid predators.The sea cucumber ranges in size from. 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.
Distribution and habitat
The enypniastes can be found mainly in the benthic zone of the ocean. They can be found all over the globe in many different regions. They spend most of their time in the water column, touching down on the seafloor only to eat.The first sighting in the southern ocean waters occurred in October 2018, when a team from Australia's Department of the Environment and Energy caught an image of E. eximia on a camera that had been deployed in seas near East Antarctica.
