Concerning message #22593:

Here are some more photos from Lembeh of the same type of situation, with the aeolid nudibranchs feeding on the eggs, and also possibly laying eggs of their own.

Thanks Tony,

It will be interesting to discover just who made the eggs this nudibranch is eating. I suggested early on that they look like polychaete eggs but in other messages it has been suggested they are most likely the eggs of shelled cephalaspidean 'slugs'. The reason I suspected they were worm eggs were because the individual eggs seem to be scatterd at random rather than being arranged in strings which is what opisthobranchs do. I am not sure whether your original photos can show such microscopic detail but it would be nice to see if there is a 'string' linking the eggs to one another in a single row

Best wishes,
Bill Rudman
