The dominant group Coleoidea (with one extant subdivision--Neocolioidea) includes species with an internal shell, such as squid (Teuthida), bobtail squid (Sepiolida), cuttlefish (Sepiida), octopus (Octopoda), and Vampyromorpha.

The COI gene for phylogenetic analysis of the coleoid cephalopods exhibited a high degree of nucleotide sequence variability, with one half of the sites varying in at least one taxon; COI amino acid sequences were highly conserved, but were useful in determining basal-level relationships among the Coleoidea
