From: Akos Lumnitzer

Dear Bill,

Could you please ID this beasty for us? My fiancee found it at 12 meters of depth off Kurnell, Botany Bay, Sydney, New South Wales, on the 9 April 2000.

It was about 2cm long.

Thanks
Akos

Dear Akos,
This is quite an interesting find for so far south, but considering the unusual oceanographic conditions on the east coast of Australia at present, with unseasonably warm water, it is not unexpected. This is Chromodoris roboi. It is nice to get a 'typical' spotted form to match the 'lined' form from western Australia. [See messages below]

Also of interest is the purple sponge on which it is crawling, which is most probably its food. Even when larvae of tropical animals survive the journey south, they still have to find either a colony of their tropical food, which has also made the journey successfully, or find a temperate water substitute.

Best wishes,
Bill Rudman.
