Species Account:

        This remarkably small (2mm shell) Colpodaspis species is considered to be uncommon in Okinawan waters. I've personally never seen it in the waters of Okinawa's main island during many years of diving there. This attractive little cephalaspid was photographed and collected by Atsushi in the Keramas.* The above photograph was taken by Atsushi from the waters of Zamami Island on the 25th of May, 2015 and he reports (pers. comm.) finding it between dead corals and stones. He also mentions seeing more than ten individuals during diving in the Keramas. Atsushi's photograph is used here with his kind permission.

        There is an additional example of one of Atsushi's earlier photographed Colpodaspis sp. 2 animals on the Sea Slug Forum (Rudman, 2000).

        I've previously featured the following Colpodaspis on these pages, one described species and with the current animal, two unknown species from Okinawan waters.
