Bobtail squid are a group of cephalopods closely related to cuttlefish. Bobtail squid tend to have a rounder mantle than cuttlefish and have no cuttlebone. They have eight suckered arms and two tentacles and are generally quite small.
Sepiolidae is a family of bobtail squid encompassing 15 genera in three or four subfamilies. A gladius is absent in subfamily Heteroteuthidinae, and in subfamily Sepiolinae it is reduced, or absent like in genus Euprymna. A third subfamily is Rossiinae, and the genus Choneteuthis is considered to be Incertae sedis. Though 72 species have been recognized in Sepiolidae, the validity of a few of them has been questioned.
Histioteuthidae is a family of Oegopsid squid. The family was previously considered to be monotypic but the World Register of Marine Species assigns two genera to this family.
Euprymna tasmanica, also known as the southern dumpling squid or southern bobtail squid, is a bobtail squid that lives in the shallow temperate coastal waters of southern Australia's continental shelf. It lives for between 5 and 8 months and the adults can grow up to 6 or 7 cm long with a mantle length of 3 to 4 cm. They are found in seagrass beds or areas with soft silty or muddy bottoms from Brisbane on the east coast to Shark Bay on the west, as well as around Tasmania. Southern dumpling squid are nocturnal and during the day hide in sand or mud covered in a mucus-lined coat of sediment. If disturbed acid glans can quickly remove this coat as an additional decoy to ink squirting.
Taoniinae is a subfamily containing ten genera of glass squids.
Euprymna stenodactyla is a species of bobtail squid.
Sepiola rossiaeformis is a species of bobtail squid native to the Indo-Pacific. Its exact range is unknown.
Euprymna albatrossae is a species of bobtail squid native to the western Pacific Ocean off the Philippines and Japan. The depth range of E. albatrossae is unknown. The type specimens were collected using a nightlight.
Euprymna hoylei is a species of bobtail squid native to the tropical waters of the Indo-Pacific, specifically the western Pacific Ocean and northwestern Australia. Little is known about the size range of this species.
Euprymna penares is a species of bobtail squid native to waters of the Indo-Pacific; its exact distribution is unknown. Little is known about the size range of this species.
Euprymna phenax is a species of bobtail squid native to the waters of the Indo-Pacific, off the Philippines and possibly in the East China Sea. The depth range of this species is unknown. It was originally collected at nightlight.
Euprymna scolopes, also known as the Hawaiian bobtail squid, is a species of bobtail squid in the family Sepiolidae native to the central Pacific Ocean, where it occurs in shallow coastal waters off the Hawaiian Islands and Midway Island. The type specimen was collected off the Hawaiian Islands and is located at the National Museum of Natural History in Washington, D.C.
Sepiolinae is a subfamily of bobtail squid encompassing 5 genera and more than 30 species.
Inioteuthis capensis is a species of bobtail squid native to the southeastern Atlantic Ocean, specifically from Lüderitz Bay to Mossel Bay off South Africa.
Inioteuthis is a genus of bobtail squid comprising three species.
Sepiola is a genus of bobtail squid comprising around 15 species:
Euprymna berryi, commonly called hummingbird bobtail squid or Berry's bobtail squid among various other vernacular names, is a species of mollusc cephalopod in the family Sepiolidae.
Euprymna morsei, the Mimika bobtail squid, is a species of Indo-Pacific bobtail squid from the family Sepiolidae.
Rossia is a genus of 10 species of benthic bobtail squid in the family Sepioidae found in all oceans. They live at depths greater than 50 m (164 ft) and can grow up to 9 cm in mantle length. This genus was first discovered in 1832 by Sir John Ross and his nephew James Clark Ross in the Arctic Seas, showing a resemblance to another genus under the same family, Sepiola. After returning from their expedition, Sir Richard Owen officially classified Rossia to be a new genus, naming it after Sir John and James Clark Ross.
