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).

@jeffgoddard Is this a particularly lovely D. venustus or something else? Prominent white tips and proportionally stout rhinophores, no white line on foot. Dots were larger than normal for D. venustus and white, not yellow. About 15 mm Found by @seaslugin; here's her photo: https://www.inaturalist.org/observations/58060058.

Undescribed species, 22 mm long. I spotted this specimen on its flat, coiled egg mass (also see 2nd image) on a pebble grabbed with gray mud from 186 m depth off Cape Alava, WA while on a cruise AR-04-04 of the NOAA Ship McArthur II in June 2004. The translucent dorsum was finely scabrous to the touch. The 4th image is an SEM, made by Sandra Millen (UBC), of some of its radular teeth. Sandra confirmed this as an undescribed species and last I heard had been well along in describing it. The first three images were scanned from prints I took shipboard using 35 mm film. The specimen, including two SEM mounts, was deposited by Sandra Millen in the California Academy of Sciences (CASIZ 176807).

6.8 mm long. Found in a shallow, low intertidal pool at South Casa Reef. CASIZ 189422.

This is Eubranchus sp. 2 of Behrens & Hermosillo (2005), which so far is only known from La Jolla, California and remains undescribed. Note: in April 2021 we found one at Tar Pits Reef in Carpinteria, Santa Barbara County: https://www.inaturalist.org/observations/75602522

The white patch on the head, reddish hepatic region, white anal papilla, and rings of papillae on the cerata are distinctive.

The 3rd and 4th images show egg masses, containing early and late-stage embryos, respectively, laid by adult pictured here. The last image shows a newly hatched veliger larva, right lateral view, with a shell 210 microns long.

Photographed by my colleague and fellow nudibranch aficionado Dr. Tara Prestholdt, Professor of Biology, University of Portland, who found this with her students on one of her popular, week-long field trips on the Oregon coast.

Tara kindly gave me permission to post this and the next photo, as this one is the northernmost existing record of C. spadix, and the next one shows that it can co-occur at the same site with its sister species.

Note: when Tara finds the time to start her own account on iNaturalist, and posts these same images, I will delete them from my account; for now we just wanted to make her pair of observations publicly accessible.

Holotype (CASIZ 182590), 33 mm long as shown here, on which Terry Gosliner based his 2010 description of this species (as Flabellina goddardi). I found it on a calm and bright overcast morning crawling in the open in a low intertidal pool at Tar Pits Reef. The 2nd image shows the egg mass, 14 mm in diameter, laid by this individual on 10 May 2008. The uncleaved zygotes averaged 65 microns in diameter, were packed one per capsule, and took 7 days at an average of 16 degrees C to develop into hatching planktotrophic veligers. The 3rd image shows, in right ventro-lateral view, one of the veligers just prior to hatching and with a shell 105 microns long.

Unlike most specimens of this species observed subtidally, individuals found intertidally vary in possession of white lines on the body and cephalic tentacles from completely absent (as in this specimen) to incomplete, to complete. With those white lines, subtidal specimens have occasionally been mistaken for Coryphella trilineata.

La Paz, B.C.S., Mexico
Three of these, found together under a rock with sparse hydroids. Each only about 2-3 mm - quite small. At first, I thought they might be odd Tenellia albocrusta. (B.C.S. is the southern range limit of C. albocrusta according to Gary’s iNat guide: https://www.inaturalist.org/guide_taxa/933633#ref2)

But the thing that gave me pause was how extensive the opaque white speckles are - extensively down the oral tentacles (not seen in any other photo of C. albocrusta on iNat) and the entire length of the rhinophores. All three had the same markings.

In Camacho-Garcia, Gosliner and Valdes, “Guia del Campo de las Babosas Marinas del Pacifico Este Tropical,” 2005, p. 105, a tiny Cuthona Sp 6 looks like a possibility - the photo isn’t reproduced well, but there seems to be white on the oral tentacles (not mentioned in the text, so I may be seeing something incorrectly) and white spots on the rhinophores are mentioned. I haven’t seen more recent information on this Cuthona.

From TGosliner: "This looks like something entirely new to me! It certainly is not Tenellia albocrusta. The head shape and ceratal color are entirely different. Very cool!"

Here we go again! I sure appreciate everyone's help on these.

  • About 4 mm long
  • Found on Tubularia
  • Body: Translucent (you could see organs) with white speckles
  • Rhinophores: Smooth, tapering, clear, tipped with white frosting
  • Oral tentacles: beige, with faint line of white specks
  • Cerrata: beige, tipped with white, darker brown at the base, with both white and brown specks
    BEST GUESS: A beige Catriona rickettsi (looks like this one photographed by David Behrens: invasions.si.edu/nemesis/calnemo/SpeciesSummary.jsp?TSN=7...)

maybe a stretch of the imagination but:

  • forgot that the dorsomedial markings are the major distinction, didn’t get great shots. on the images of the tail you can see the olive marking extending up the dorsum?
  • not sure if the cerata are irregularly nodular.

Please leave at genus for now. Preliminary ID by @tgosliner is Catriona group of Tenellia species. Thank you also @jeffgoddard for your ID help.

They were not tiny -- all were between 15-25 mm long.

Non-scientific description:

Body was translucent white with no other markings. No foot corners that I could see.

Ceratal cores were brown with orange tips, with varying degrees of faint opaque white frosting on the leading edge of the cerata, ranging from virtually none on the smaller individuals to obvious on the largest individual.

Rhinophores were smooth with opaque white on the backside of the tips, with a small orange-red patch just below that (barely extended to the front of the rhinophore, so not really a "band").

Oral tentacles were about the same length as the cerata, with a red-orange patch on the leading edge that did not extend to the tip. As with the rhinophores, the oral tentacles had varying degrees of opaque white frosting on the leading edge of the cerata, ranging from virtually none on the smaller individuals to obvious on the largest individual. On only the largest individual, the opaque frosting extended into the head.

The white tipped cerata have a reddish or brownish red core and may have a greenish cast, and form up to 10 comb shaped rows. Rhinophores are perfoliate and frosted white along most of their length, and oral tentacles have a white line on their dorsal surface”

opaque frosting on the rhinophores appears to be on the top only
