Thecacera pennigera?

Bill,

Could you see if the attached nudi is Thecacera pennigera? We found heaps at Fly Point, Port Stephens, New South Wales, last weekend. Ours have more yellow and dark blue spots with a translucent cream body. They have been around for about 4 months now. I haven't noticed them before in my 13 years of diving Fly. Wayne may have? We have been diving in different areas this year, though. Sorry the photo is not the best. We will try to get some better ones over Christmas. I may resort to taking a "background" with me.

Thanks,
David & Leanne Atkinson.

Yes its Thecacera pennigera. originally described from England but now known from many parts of the world. It feeds on bryozoans which foul the bottom of ships, so it possibly has spread around the world in the last 150 years. Where it originated is still a mystery. Bill Rudman
