HI
Is this nudibranch a Nembrotha?

It was taken October 2002, Police Pier, Lembeh Strait.

Thanks
Sarah

Dear Sarah,
Some species of Hypselodoris do look quite like a species of Nembrotha, but they feed on ascidians, and happily your photo shows the animal feeding on a sponge. The brightly coloured cone sticking out the front of the animal is the oral tube which usually lies inside the 'mouth'. Only when feeding is it pushed out so the feeding apparatus - the jaws and radula - can make contact with the sponge food. This animal is Hypselodoris nigrostriata, and as far as I know this is the first information we have on which sponge it eats.
Best wishes,
Bill Rudman
