The class is Cephalopoda ("head-foots") also along with the cuttlefish, there are the squids and nautilus. The class is considered to be the most evolutionary "advanced" of the invertebrates. Around 600 species living, all marine-- I believe. An interesting note---octopus show very good parental care and squid are believed to have a "better engineered/designed" eye then vertebrates. A whimsical notion by J. Diamond (sp?). If everything was created by design---then God is a squid :-). Shan
