About Chiridota heheva

Chiridota heheva is a species of sea cucumber in the family Chiridotidae. The species is known from deeper regions in the Western Atlantic Ocean, but has a cosmopolitan distribution. It was described by Pawson and Vance in 2004. It occupies all three types of chemosynthetic ecosystems: hydrothermal vents, cold seeps, and organic fall. Unlike many other animals in similar environments, they do not host chemosynthetic bacteria.
