Cephalaspideans and Anaspideans
This page contains some of the Cephalaspidean and Anaspidean opisthobranchs. We have not spent a lot of time searching for and photographing members of these groups, particularly the cephalaspideans, so our coverage is far from complete. Also, some of the identifications are uncertain. Unlike nudibranchs, many species in these two groups possess shells, exposed in some and internal in others, and in many cases species were originally described solely from empty shells.
Although slower to load, this list with thumbnail images is available here.
