Dear Grey,
This is Nembrotha cristata. It is very similar in colour to one of the forms of Nembrotha kubaryana differing mainly in the absence of any orange colouration. If you ever get the chance it would be useful to get some biological information on these animals - about their egg masses and what food they eat etc. Photos are a good way amateurs can help to build up our knowledge about marine life. It would be foolish to say Species 'X' eats sponge 'Y' just because we have one photo of it sitting on the sponge, but if over a number of years we only have photos of it associated with a particular sponge, or in the case of a Nembrotha, a particular ascidian (sea squirt), then we can be pretty sure there is a connection between the two.

Bill Rudman.
