Her is another nudi I'd like your help to ID please. It was found at about 30-40 feet on dark volcanic sand at the dive site called Mentang Wall on a volcano off Lombok, Indonesia. Day dive, in May 2002. Overall size no more than one inch. Very well hidden in natural light, but photo shows lovely colours
Hope you can help,

All I can say is that it is a tritoniid nudibranch, probably of the genus Marionia. The orange-red patches down each side may be a distinctive feature, but species seem to be quite variable in colour so what is distinctive in this specimen may be not be very noticeable in another animal.
