The first photo is the cercaria stage shed from a planorbid snail collected from a pond at Pleasanton Ridge Regional Park. The second photo shows an infected Pseudacris sierra from the same pond.

5 mm long. This is the southern form, with the orange lines on the body, described by MacFarland (1905) as Ancula pacifica. Found in northern Oregon during the strong 2015-16 El Nino.

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.

Six mm long, one of two specimens found by Ziggy Goddard under cobbles while snokeling in shallow water. The cephalic tentacles of this specimen looked a little worse for the wear; I'm not sure if they were damaged moving it for these photos or not.

22 mm long. One of four found in an oyster reef matrix on a mixed mud/basalt shore inside Bahia Falsa near San Quintin.
Described by Millen and Bertsch in 2005 as D. behrensi, this species was determined to have been described 100 years earlier by Cockerell (in Cockerell & Eliot, 1905) as D. nigromaculata.

Pacifia goddardi was located at a depth of 35 feet on reef. Lengths were 1 cm. Water temperature was 56 degrees F.
Nudibranchs are commonly found near their food. In this image there appears to be one type of hydroid. The food source of P. goodardi is reported to be Bougainvillia-like species B (Goddard & Hoover, 2016). The thecae of this species have been observed to be sand encrusted and the hypostomes were salmon-colored. The thecae in the lower left of this image appear to match the description of the food source of P. goddardi, but in the present image the hypostomes of the hydroids appear lighter in color. It is not clear if the hydroids in this image are the food source of P. goddardi. Considering that this species has been found repeatedly at Point Dume during the last 5 years, and that 5 individuals were observed during this survey, Point Dume would be a good site for further attempts to document feeding behavior of P. goddardi.

This is Cuthona luciae (Valdez, 2016 via DNA testing) - ID is controversial, WoRMS currently recognizes it as Cuthona herrerai (not DNA tested), another previous ID was Cuthona caerulea.
