Okenia mellita - new area of Ningaloo Reef

The other day I found another orange and black nudi that may be an Okenia mellita. This one was in a completely different area and much deeper than the others.

Dear Kristin,
It looks like you have a resident population of this species. It certainly looks like O. mellita, except for the absence of white lines. As I mentioned before I would need to look at its anatomy to be sure. It would be interesting to know what it fed on. I suspect an encrusting bryozoan, so if you have any photos of it on a possible food source they would be interesting to see.
Best wishes,
Bill Rudman
