Doriprismatica sibogae

Also known as Glossodoris sibogae

Comment from expert, Richard Willan: This chromodorid nudibranch is extremely similar to the very variable Glossodoris atromarginata, but its colour is supposedly “much more intense” with the background being bright brownish yellow as in this photo. More importantly, its radular teeth are only half the size of Glossodoris atromarginata. Glossodoris sibogae is presently only recorded French Polyneisa (where it is very common), Fiji and Indonesia.
