Bathykorus

Genus of hydrozoans

Bathykorus bouilloni is a species of hydrozoan first described in 2010. It is a deep-sea species found in the Arctic Ocean, and appears to be common at depths below 1,000 m (3,300 ft). It is the only species in the monotypic genus Bathykorus. The genus name comes from the Greek bathy meaning "deep" and korus meaning "helmet", referring to the depth at which this species is found and to the shape of the bell. Its helmet-like appearance bears a resemblance to the helmet of Darth Vader, giving it the nickname Darth Vader jellyfish. The specific name is in honour of Dr. Jean Bouillon, (1926–2009), a marine zoologist.
