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.
Idiosepius thailandicus is a species of bobtail squid native to the Indo-Pacific waters off Thailand. The extent of this species' distribution is still to be determined and records of Idiosepius dwarf squid away from Thailand, south to Indonesia and north to Japan, may be attributable to this species.
Sepiola atlantica, also known as the Atlantic bobtail, is a species of bobtail squid native to the northeastern Atlantic Ocean and the Mediterranean Sea.
Sepiolina nipponensis, also known as the Japanese bobtail squid, is a bobtail squid and the only species in the genus Sepiolina. It is found in the Western Pacific in apparently widely separated populations, the most southerly of which is in the Great Australian Bight in South Australia and West Australia and then there are populations from the Philippines northwards to Taiwan, Fujian and southern Honshū.
Sepiolina is a small genus of bobtail squid in the family Sepiolidae and the subfamily Heteroteuthidinae from the western Pacific Ocean.
