Photo of Halgerda graphica

Hi Bill
I was browsing the Seaslug Forum and came across your note on Halgerda graphica. I have seen this species on several occasions in South Australia, on southern Yorke Peninsula. The attached photo is from a about 10 years back, Port Moorowie, on open sand, 8m water, between limestone reefs on a reasonably exposed coast. This specimen was put into the SA Museum collections.

Thanks Nigel,
This is a very useful addition to the Forum, and to our general information on the genus. It is the first photo I have seen from South Australia, from where the species was described, which matches the original painting. Neville Coleman (1989) has a photo from Cockburn Sound, Western Australia, which could be this species, but it has many more orange lines, and they are not arranged in the same reticulate pattern. I am sure Shireen Fahey will be interested to know of this specimen.
Best wishes,
Bill Rudman
