Elysia tomentosa from Moreton Bay, Queensland

August 25, 2008
From: Stan O'Donnell

Hello,

Let me just say I love the sea slug forum. I collected this nudibranch a few weeks ago when I was collecting some Caulerpa from Cleveland in SE Queensland Australia. It appears to be some type of Elysia. I have looked through the species list on the forum but could not find any thing that looks the same. I was hoping you might have some ideas as to what this nudibranch could be. I look forward to your reply.

Dear Stan,

It is indeed a species of Elysia, and I am pretty sure it is Elysia tomentosa. As you will see from the Fact Sheet and attached messages, there is still some uncertainty surrounding the identity of this animal but this is the best bet at the moment. The pink parapodial border, outlined in black, seems to be quite characteristic. By the way, although species of Elysia are sea slugs they are not nudibranchs. In some books these two words are considered to mean the same thing, but sea slugs [= opisthobranchs] include not just the nudibranchs, but also the sacoglossans [such as Elysia], the cephalaspideans [bubble shells etc], the anaspideans [sea hares]  and a number of other smaller groups.

Best wishes,
Bill Rudman
