Species Account:
Although only five specimens of Chromodoris coi have been collected, these attractive chromodoridid are considered to be uncommon, instead of rare on Okinawa, as I have seen and photographed a good many more than have been collected.
The featured animal was found crawling amid mixed strewn coral rubble and silty-sand, beneath the Tengan Pier.
