Hypselodoris from Ningaloo Reef, WA

Dear Bill,
Here is another photograph from our recent dive trip to the Ningaloo Reef, Exmouth, West Australia.
It was taken at 15m,'Labyrinth', March 28, 2000. It is identified 'Sea Slugs of WA' as a Chromodoris sp. (#159) with limited records in WA, so this would be another one.
Thanks!

Koninx, J-P, 2000 (May 6) Hypselodoris from Ningaloo Reef, WA. [Message in] Sea Slug Forum. Australian Museum, Sydney. Available from http://www.seaslugforum.net/find/2343Dear Jean-Paul,
I think this is another of those peculiarities which seem to be found in Western Australia. I think this 'species' or 'colour form' is closely related to Hypselodoris emma. I know that it may stretch credulity to compare a species with red lines down its back with one with a large reddish band, but in all other features, including anatomy, this animal is very similar to H. emma. The background yellow, the purple edge to the mantle, the gills and rhinophores and even the reddish band that joins the two rhinophore pockets together are the same. I will try and find a photo showing its head to include on the Forum.
All I can say is the jury is still out on this one but your record is a useful addition to our knowledge.
Best wishes,
Bill Rudman.
