description Cycloteuthis sirventi Overview
Cycloteuthis sirventi is a deep-sea squid in the family Cycloteuthidae and is generally treated as the type species of its genus. It is known mainly from the Atlantic Ocean and neighboring Southern Ocean waters, where specimens have been collected at bathypelagic depths.

As with many deep-water cephalopods, relatively few specimens have been collected, leaving much of its biology undocumented.
