Hi Bill,
Just thought I'd share a couple of pics of Nembrotha rutilans from Fly Point at Nelson Bay, NSW - Australia. This pair have been in the same location for about a month [March/April 2003] and I have seen them mating and laying eggs. This is now officially my favourite nudibranch species.
Cheers,
Dave

Thanks Dave,
In your upper photo the left animal is crawling on a solitary ascidian, Clavelina meridionalis (Herdman, 1891) which is quite easily recognised by its stalk, and the yellow streak in the 'body'. It has obviously found a little group of this ascidian which I suspect it is eating. In your lower left photo it is crawling over two of them. From the other messages on the Forum, N. rutilans seems to have a taste for a variety of ascidians. I was interested in your comment about them mating and laying eggs. Were the eggs the same as those illustrated in David & Leanne Atkinson's photo?
Bst wishes.,
Bill Rudman
