Sea Hares [family Aplysiidae] ,gained the common name from their side-on appearance , the rolled tentacles [ rhinophores ]just behind the eyespot
look like the big ears of a hare. They have a small internal shell and large parapodial flaps extending up from the foot & over the body .We have seen them grazing on sea grass near Fisheries Beach and on algae at Turingal Head.
They mate in large groups ,clusters of animals or long chains……. we observed both at Turingal.
We think these shown are Aplysia sydneyensis but from various references it is not conclusive.
