Just wondering if someone could identify this sea slug for us. It was found at Long Reef Marine Reserve in a large tidal rock pool.
Locality: Long Reef Rock Platform, Collaroy, 0 - 1 metre, NSW, Australia, Pacific Ocean, 8 August 2006, Tidal rock pool. Length: 50mm. Photographer: Don Miles.
I have included some photos taken through a plastic specimen container showing the top and underside of the slug.

From the general shape I would suspect that this is a juvenile of the large sea hare, Aplysia extraordinaria. They are normally more brown in colour, but it is possible that juveniles, if feeding on red algae, would have a pinkish tinge. Unfortunately we know very little about the life history of this species.
