''Psychropotes'' is a genus of sea cucumbers in the family Psychropotidae. The members of this genus possess the ability to swim, although this is only facultative.
Description
As adults, species of ''Psychropotes'' are roughly cylindrical in shape and red to violet in colour. They have a sail-like appendage which can be used for swimming during the larval stage, but is no longer needed when it is fully grown. Larvae of ''Psychropotes'' species are

and swim around using the aforementioned appendage, however researchers are still trying to understand its use when the holothurian is fully grown. Larvae are transparent and can grow to around 2 cm long.
