Hi Bill and everyone!
The Sea Hare that Aimee found is Aplysia dactylomela. It is the only large common Sea Hare I have found here on the Sunshine Coast. The telltale give away is the black tail.
Locality: Sunshine Coast near Mooloolaba, 100 mm, Queensland, Australia, Pacific Ocean, 09 October 2007, Intertidal. Length: 180 mm. Photographer: Gary Cobb.
Cheers

Thanks Gary,
There is not enough detail in Aimee's photos to be sure of the species, from the photos alone but I am sure from your local knowledge that you are right. We tend to think of large black rings when we mention A. dactylomela, but a quick look at earlier messages on the Forum, shows how the rings can be very small in some individuals. The black patch on the posterior part of the foot is a good indicator, if present, but it is not always present. Another character of A. dactylomela which distinguishes it from many other species, is that the body wall and parapodia are thicker - almost leathery to touch, rather than the thin and 'squashy' feel of most Aplysia.
I couldn't resist including your lower photo although it doesn't show much anatomical detail. It looks more like a dog swimming than a slow moving 'sluggish' sea hare. I guess the true interpretation is that it is holding on with grim determination as the current tries to wash it away
Best wishes,
Bill Rudman
