Postcard from the Reef – Rosy Phyllidia

A nice day for a dive, and a new species of nudibrach for me. At first I thought it might simply be a juvenile P. varicosa, but there were no yellow pertuberances. Getting back I hit the books, no doubt, P. rosans. New species! This fellow was in a cave at Puako I have entered a dozen times. Even in a place I have often explored I can find something new…
