I couldn’t quite believe my eyes. It was tentatively swimming with a few juvenile zebra-striped surf chub in a large tide pool, but it was generally more shy. Eventually approached near enough for me to snap a few pics.

Found on Halimeda sp. that appeared significantly larger than the typical H. tuna seen in Bermuda. Potentially Halimeda opuntia which is the typical diet of this species (unfortunately I neglected to take a photo of the alga).
Matches the description in Krug et al. (2016) Molecular and Morphological systematics of Elysia Risso, 1818 (Heterobranchia: Sacoglossa) from the Caribbean region, and that in Valdes et al. (2006) Caribbean Sea Slugs field guide.
Some defining characteristics:
Cephalic region becomes continuous with the body.
Cephalic furrow is pronounced on the animals right side, leading into a white spot.
Eyespots are set further back that what would be seen on Bosellia mimetica.
A faint dorsal line can be seen indicative of the region where the parapodia have fused to the body

My friend Melissa is the finder. I think she saw them yesterday and told me. I can't find her on iNat to tag her.
I saw 8 individuals.

Both C. perca slugs I found yesterday at Lake Merritt seemed to have some sort of evenly-spaced, stalked growths on all their surfaces, perhaps some sort of parasite, fungus, virus or ? The overall impression was "furry." The other one, which I brought over to the microscope (https://www.inaturalist.org/observations/240871810), also shows these growths and was photographed by @audreyfalconer1, @pacificplankton, @leslieh, @ktnoonan, @chilipossum and possibly others as well.
Water quality data:
Temp: 23.6 degrees C
SAL-ppt: 33.93
pH: 7.89
DO: 86.6 (top)
Update: those might be ciliates in genus Scyphida, according to Jeff Goddard (see comments below).

We found this species and its egg masses (4th image) inside the folds of basketball-size specimens of the brown alga Hydroclathrus clathratus at the water's edge on a cobble beach at low tide. Scanned from 35 mm slides.

This nudi was about 5mm long. It looks like a juvenile of a Rabbit Dorid, Cockerell’s Dorid, or a Clown Dorid without the orange tubercles typically seen on adults. Maybe it’s not one of them. Any help is appreciated. Thx
