This unusual nudibranch appears to be an aeolid, of the genus Phyllodesmium, but that's only an educated guess. I couldn't find a close match to any other slugs I'm aware of. This aeolid is only about an inch long. Like all aeolids, the elongated cerata on its back house the digestive glands, and near their tips are special sacs that store undigested nematocysts from their prey, used in defense.

identification (best guess):
Phyllodesmium sp.2

Pyllodesmium sp. (frame #35)  21 Nov '97
