Tylodina corticalis from New South Wales

Dear Bill,
After reading Gary Cobb's message about Tylodina corticalis we remembered we had some shots of it in the Port Stephens area. You didn't have any from there on the Forum, so here are three shots, the third one shows some of the foot. These are not a common sight but we have seen it on more than one occasion.

Dear Leanne & David,
Thanks for these photos. I have included a close-up of the head of the Little Bay animal as it shows the structure of the rhinophores and oral tentacles very well. The rhinophores are an open rolled cylinder at the top - much like in a species of Elysia - but a littl eway doown from the tip they become a solid structure with a groove down the outer edge. You can see this groove in the left rhinophore in the photo. The oral tentacles are enrolled [see right tentacle in photo] much the the Elysia rhinophore.
Best wishes,
Bill Rudman
