Tiny nudibranchs eating/laying? even more tiny spiral egg masses on the underside of the sand collar. Given that it’s preferred food is Harminoe eggs and those egg masses were all over where we found the Olea, my money is on these spiral masses being Olea eggs rather than their food (also the small aggregation of individuals) @anudibranchmom ID

I wasn't expecting to find this this morning, especially crawling on algae pretty much out in the open (it was almost under a rock ledge). Northern range extension from Carpinteria, CA. About 13 mm long.

Amazing encounter watching this lizard biting snake. Snuggled up to tire after we stopped to look. (Not stuck or driven on!) Eventually all departed separately. Lizard ran down road full speed way up on its feet.

On right, with a F. trilineata at left for comparison. Both were from the same small tide pool. Scanned from a 35 mm negative.
In a post to the Sea Slug Forum (http://www.seaslugforum.net/find/2621) I had identified these as F. bertschi, but after finding more in California, realized they were different from that Panamic species. Brenna Green's work, including genetics, pinned them down as a color variation of F. cooperi.

Image by Ali Hermosillo of one of a pair of specimens I found under low intertidal coral rubble at Punta Mita in Feb 2006. CASIZ 174084. At the time this was only the 2nd record of this species outside the tropical Indo-Pacific (Camacho-Garcia et al. 2005, Field guide to the sea slugs of the tropical Eastern Pacific), and the 1st from Mexico.
Egg size (67 microns) and mode of development (planktotrophic) documented in Goddard & Hermosillo (2008, The Veliger 50:83-96).

Aplysia sp. was located under scroll algae of the genus Padina at a depth of 15 feet. Length was 1 cm. Water temperature was 78 degrees F.
I hypothesize that this is a sister species to Phyllaplysia padinae in the Eastern Pacific. Note that Phyllaplysia engeli is present in the Atlantic, but I hypothesize that P. engeli is sister to P. taylori in the Eastern Pacific. If these hypotheses are true, then this is an undescribed species.
