Belongs within: Neocoleoidea.
Contains: Loliginidae, Spirulida, Onychoteuthidae, Ommastrephidae, Histioteuthidae.
The Teuthida, squids, are a group of elongate-bodied cephalopods with the shell reduced to an internal, feather- or rod-shaped, gladius, and with ten circum-oral appendages including two contractile tentacles. The Cranchiidae, glass squids, have the coelom modified into a large buoyancy chamber that allows the squid to float passively in the water column.
