Dear Dr.Rudman
I found this slug and two similar ones [message #12247, message #12248] at Okinawa.
Are they Hypselodoris bullocki?

Takahashi, K., 2004 (Feb 19) Thorunna halourga from Japan.. [Message in] Sea Slug Forum. Australian Museum, Sydney. Available from http://www.seaslugforum.net/find/12158Dear Kunihiro,
Your three slugs all looke quite like H. bullocki, but they are three different species. I can't be 100% certain of my identifications because we don't know very much about colour variations in any of these species. In fact we only discovered that some of them were distinct species after we had looked at their anatomy and the shape of their radular teeth.
I am pretty sure this one is Thorunna halourga. Some of this group of similarly coloured species can be seen on a separate page, but since I prepared that page, more similarly coloured species have turned up and need to be added
Best wishes
Bill Rudman
