Dear Bill,

You will find attached, a photo of what is believed to be a juvenile specimen of Hexabranchus sanguineus taken at Dauin, Negros Oriental, Philippines on a recent trip.

What do you think?

Cheers;

Michael D. Miller

Dear Mike,
Yes its a juvenile Hexabranchus sanguineus. It's a bit hard to see from the photo but each gill is separately attached to the mantle, just as in the adults, and of course its radula is quite different.

It has a remarkable resemblance to some purple spotted chromodorids such as Hypselodoris maculosa, Thorunna australis and Chromodoris decora.
