Cephalaspideans

This page contains some of the Cephalaspidean (bubble shells and their relatives) and Acteonid opisthobranchs. We have not spent a lot of time searching for and photographing members of this groups, so our coverage is far from complete. Also, many of the identifications are uncertain. Unlike nudibranchs, many species in this group possess shells, exposed in some and internal in others, and in many cases species were originally described solely from empty shells.
