Dear Bill,
Here is an image of a specimen of Aphelodoris berghi found at Portsea Pier, Victoria, Australia on May 1st, 2003. The specimen measured 46mm in length and is the largest I have encountered to date. It was found under a rock at a depth of 4m together with a specimen of A. sp.2? (see separate message).

Best wishes,

Thanks John,
I've seen very few speimens of this species so every photo helps to give us a better idea of the variability of its colour pattern.
Best wishes,
Bill Rudman
