''Iridoteuthis iris'' is a species of bobtail squid native to the northern central Pacific Ocean; it occurs near the Hawaiian Islands off the southeast and northwest Hancock, Colahan, and Kammu seamounts. There exists a doubtful record from the Ceram Sea. Unlike most other bobtail squid, ''I. iris'' is pelagic and lives in the open ocean.〔Reid, A. & P. Jereb 2005. Family Sepiolidae. ''In:'' P.
