Note:

Different taxonomic schemes between Engeser and Felley et al. make comparing and combining their data's a difficult and frustrating process. Engeser treats all Recent sepioids as a taxon Sepiina. Felley et al split Recent sepioids to groups Sepiida and Sepiolida. Thus this presentation is a taxonomic hodgepodge without a prevailing taxonomic view over either of them.
