Found in low rocky intertidal. Image scanned from a 35 mm slide.
9 mm long; found under a low intertidal cobble. Scanned from a 35 mm slide.
3rd image shows the slug as found on the underside of a low intertidal boulder. I found one other specimen of this species on this date.
About 20 mm long, found under a low intertidal cobble.
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.
With its egg mass on the underside of an intertidal boulder.
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.
Found as is next to the dark sponge and close to its yellow egg mass. Underside of limestone rubble.
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.

Pacifia goddardi was located at a depth of 35 feet on reef. Length was 1.5 cm. Water temperature was 56 degrees F.
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.
Mated pair laying eggs, most likely an introduced Pacific species.
~10mm long
~2 metres deep.
Under rock.
Tentative ID.
Undescribed Cuthona sp. or variation of Flabellina dushia.
Cuthona sp. 2 in REEF Creature ID (could also be a variation of Flabellina dushia, will require DNA testing to sort out).
Cuthona sp. 2 in REEF Creature ID (could also be a variation of Flabellina dushia, will require DNA testing to sort out).
Doriopsilla albopunctata was located on a boulder on sandy substrate at a depth between 20-35 feet. Length was between 1.5-3.5 cm. Water temperature was 65 degrees F.
Matches Cuthona sp. 2 in the REEF Creature ID Florida Bahamas Caribbean 3rd ed. pg. 236. Could be a variation of Flabellina dushia, DNA testing needed to sort it out.

Finally and at last, another specimen of this little beauty, which I first observed last November (https://www.inaturalist.org/observations/18597683). These are the only specimens of this species I have ever seen anywhere!
Shell 7.4 mm long, found on the underside of a low intertidal boulder, along with two small Conualevia alba and a good size Stenoplax conspicua (see 3rd image, which shows the clam as I found it after turning the rock). 4th image shows the cobble field where I found this specimen, as well as the two last November. The last two images are of this specimen relaxed in MgCl2.
Shell about 10 mm long. Found two on sand under a low intertidal boulder. Very extensible, active, blade-shaped foot and tentaculate mantle covering most of the shell. I don't recall ever seeing this species before, and with that active, white-striped foot, it was eye-catching. The last image shows one of the specimens as found, at the entrance to a burrow of unknown origin, but possibly constructed by Neotrypaea biffari, which are frequent in the boulder field at Naples Point.
The long foot, long tentacles, and mantle covering most of the shell place this little cutie in the Galeommatoidea.
Robin Agarwal (@anudibranchmom) was with me in the field when I spotted these and got a great video clip of one using its foot to move step-wise: https://www.flickr.com/photos/30314434@N06/31128212317

Third sighting of this mystery slug!
HELLO AGAIN.
This is now the second time I've photographed this undescribed nudibranch - the first one was found by Luan Roberts when we were dock fouling in August 2021: https://www.inaturalist.org/observations/91369989
Unfortunately I did not have collecting materials with me, and I couldn't detour via CAS, so it got to go about its nudibranch business after these photos were taken.
This mystery slug does not appear in Behrens et al, Eastern Pacific Nudibranchs, 2021, nor have I found any references to it elsewhere.
Found by @luanroberts. About 7 mm. Orange bands on white-tipped oral tentacles, orange bands on the white-tipped rhinophores, and white specks on the surface of the body.
Obelia and Tubularia (Pink-mouth hydroid) present elsewhere in the marina in small quantities, but didn't see it feeding.
Looks vaguely like the pale one in the left-side photo on Page 124 of Behrens & Hermosillo's Eastern Pacific Nudibranchs, 2005. Same individual as https://www.inaturalist.org/observations/91332884
Update: this hydroid https://www.inaturalist.org/observations/92299348 was the only hydroid on the boat bumper where it was found.
Could be a variation of Flabellina dushia, DNA testing needed to sort it out.
Found two together and could not get them in focus!
Found together with my other Melibe sighting from the same bay. Difficult to see on the photos - the head is to the left in each picture.
Found with their egg masses on hydroids growing on blades of kelp.
~20m depth? I'll update later with better estimate
A species of freshwater goby which we found uplands on Negros Island, inland from Dumaguete. In a clear and clean creek, these were quite abundant. The males are metallic blue/green colored, the females brownish with stripes.
Hundreds of these tiny (oral disk around 1 cm across) anemones were in the mud / sand shallows at low tide along the shore of Tomales Bay.
We found a dozen of these, up to 75 mm long, and with their egg ribbons, under intertidal cobbles in the outlet of the shallow lagoon backing Playa Pichilingue. The 6th image is of the site, taken in Feb 2020, when I returned and searched for but did not find any C. bramale.
These specimens represent the first record of this Panamic species from the the Sea of Cortez and the Baja California peninsula. It was not recorded by Orso Angulo-Campillo during his four year survey of opisthobranchs from Baja California Sur, including the La Paz area (Vita Malacologia 3: 43-50, 2005).
We documented the occurrence of C. bramale here in Goddard et al. (2018, Proceed. Calif. Acad. Sci. 65: 107-131, p. 112).
Tidepooling. Potential new species found by @chloe_and_trevor and collectively collected.
In the collection container it seemed to munch on some hydroids (photos 4-7).
