Concerning message #10847:
Hi Bill and everyone!
May I present to you Elysia verrucosa from our area. This species has been found a few times. It has a very distinctive 'shuffle' with the front end of it's head and rhinophores. Very similar to Aeolidiella alba. I have included a closeup of the egg mass with it's extra-capsular yolk.
Locality: Old Woman Island, Mooloolaba, Sunshine Coast, 15 m, Queensland, Australia, Pacific Ocean, 27 December 2005, Subtidal. Length: 8 mm. Photographer: Gary Cobb.

Note added 19 Jan 2009: probably not E. verrucosa - see Kathe Jensen's message #22159.
I have the feeling I have seen this species recently but I don't know where. It will be interesting to see whether Kathe Jensen considers this to be the same as her E. verrucosa. In the only photos we have of E. verrucosa black spots seem to dominate, but they appear to be absent in your animal. Does it grow much larger than 8 mm? Why I ask is that it reminds me of the relatively small species from the Caribbean which I have labelled Elysia cf timida. It would be nice to know what it ate. It would be interesting if its food was Acetabularia, which is the food of E. timida. There is a good photo of Acetabularia in Tom Turk's message about Cyerce [message #17518 - it is the umbrella-shaped algae in the upper left of the lower photo].
Interestingly Elysia sp. 8 [message #2148] has similar tubercles and an egg ribbon with extracapsular yoke, and Lindsay Warren mentions that it 'jerks' as it crawls along.
I'll tentatively put your message with E. verrucosa but it may not stay there long.
