Thordisa villosa? from Port Stephens, NSW

June 17, 2000
From: Ron Greer

Dear Bill,

Late last year I sent you a couple of images for ID that you confirmed as Petalifera ramosa. That week of diving was the most prolific I had seen in 10 years at Fly Point [Port Stephens, New South Wales, Australia]. Of the 25+ species I saw were 5 that I have been unable to ID. Here is one of them. I hope you can ID for me.

Regards,

Ron

Dear Ron,

I can't be 100% sure but I think this is Thordisa villosa. It usually has some black patches around the mantle edge but the shape and papillae make me think it is a pale form of T. villosa.

Best wishes,
Bill Rudman.
