Belongs within: Neocoleoidea.

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. Recent authors have often divided squids between the benthic Myopsida and pelagic Oegopsida, but relationships between these two subgroups are uncertain. The Cranchiidae, glass squids, have the coelom modified into a large buoyancy chamber that allows the squid to float passively in the water column.
