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.

Oak Gall Wasp (tentatively Feron sp.) collected as a gall on Engelmann Oak on 2/18/23 at Santa Ysabel Preserve by @madily. See discussion here: https://www.inaturalist.org/observations/149459575
Two batches of photos:
1) Live adult photos are of the live wasp, taken through the Ziploc plastic and then photoshopped. Too afraid I'll lose it if I do anything else for now.
2) Wasp died in the Ziploc 3/5/2023. Dead adult photos taken with Olympus TG-6 and added to this observation the same day. Will ship specimen to @megachile for better photography.
Possibilities: In the bag @madily gave me to deliver to the Norcal oak gall fans, I have two Englemanns twigs. The first has a single 'Feron' gall, which is still attached to the underside of its leaf and appears to have an exit hole at the top (which may have been there already, eg, an empty gall). The second twig has a leaf with both an Andricus reticulatus and a Feron gall, next to each other. This was iNatted en situ: https://www.inaturalist.org/observations/149766861 That Feron gall has since fallen off the leaf and does not appear to have an exit hole. The Andricus reticulatus gall does have an exit hole now, but that may have been there before.
Therefore... this adult could be 1) the Feron sp. inducer, 2) a parasitoid wasp; or 3) or Andricus reticulatus. Or something else that hitchhiked on the twigs, but that seems unlikely. There may be other possibilities as well!
A non-exhaustive search for online photos of adult Andricus reticulatus came up empty. Does anyone have one?

Catriona? As with the first individual (observed on a different dock), found nestled deep within a mass of hydroids, the fronds of which were populated by a multitude of tiny Orienthella trilineata.
