I found 10 of these, 2 to 4 mm long, on a very fine, filamentous green alga in a shallow, high intertidal rocky pool amongst patchy salt marsh.

Specimens match Gould's (1870) description and illustrations of this species (as Calliopaea fuscata) from Boston Harbor.

Eureka. Could this be the adult associated with laying all these egg coils?https://www.inaturalist.org/observations/218714497
I observed it for no more than a few minutes. It was about two feet away from three new egg coils. It left no trail as it wandered and circled a small area. It then decided to burrow: simply dipping into the soft sediment and within seconds it vanished without a trace, trail, or detectable hole.
~1-2 inches long, pronounced skirt, traveled quite quickly, lengthy oral tentacles.
My first one.

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.

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.

the culprit of the mystery egg sacs!!??? it was in the sea grass burrowed next to several egg masses!!
@jeffgoddard @alanarama3

last photo is not the exact eggs it was next to, just one of many seen that day, but the same type of egg mass

cruising on the sand next to fairy palm hydroids!!
who is this? super long vercose rhinophores, single broken line down the midline, frosted oral tentacles and rhinophores, speckled cerata. weird cooperi?

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...)
