Hi Bill,
Here's another one for you. This was taken in Manado, Indonesia, not sure of the depth.

Dear Tony,
This is a species of aeolid, possibly a tergipedid or a eubranchid, but I don't recognise the colour pattern, and without a better idea of its external shape and internal anatomy I can't really say much more. It seems, from the photo, that the digestive gland in the cerata forms a branching network of ducts rather than a single medial duct. If that is so it is a most interesting feature found only in some species which have symbiotic plants in their bodies. [See Solar Powered Nudibranchs Page].
Best wishes,
Bill Rudman
