I took this picture at 40 ft. while diving in the Coral Sea near Australia. Thanks to your Forum I have identified the smaller one as Nembrotha lineolata and wondered if you could help me identify the larger one next to it. Are they often found together?
Thanks for your help and this Forum.

Your mystery nudibranch is Halgerda aurantiomaculata. Species of Halgerda are sponge-feeders, while speies of Nembrotha feed on ascidians. Their appearance together is a coincidence.
