''Bathyteuthis'' is the singular genus of squid in the family Bathyteuthidae, encompassing three species. None has a mantle length greater than 80 mm. ''Bathyteuthis'' species are found scattered throughout the world’s oceans at mesopelagic to bathypelagic depths, commonly between 700 and 2,000 meters. ==Description== The arms on ''Bathyteuthis'' are short, joined by a low, fleshy web, with suckers arranged in irregular rows (two proximally increasing to four distally). Tentacular clubs are short and narrow, with 8-10 longitudinal series of numerous, minute suckers. Buccal connectives have small suckers attached to the dorsal border of the ventral arms (arms IV). Fins are small, round and separate. The head has tentacle pockets and the eyes are turned slightly to the front. Females have paired oviducts. Suckers lack circularis muscles.
