Concerning message #19106:
I think this is a color variation of Tritonia festiva? It was moving along the sandy bottom. Kind of FAT (width) I thought for a nudibranch but very neat white linear lines around the bottom of it's foot? and running from it's antennae (?) to the side/bottom.
Locality: Malibu - Point Dume, 25 feet, California, USA, Pacific Ocean, 14 October 2007, sandy bottom intertidal. Length: 4 inches. Photographer: Sheri Bauer.

Wow. Your specimen here does nothing to clear up the confusion about the large specimens of T. festiva, lacking the usual white network, that we are seeing up in Washington. In fact I would have to say that yours is Tritonia diomedea.
I base this identification on your specimens size, the number of digitiform processes on the frontal veil, and the strong white band on the foot. One big piece of evidence is that your specimen is covered with sand, suggesting it has been burrowing after sea pens. I realize this is not conclusive, but I have only seen this with Tritonia diomedea.
Thanks for sharing this,
