First time I have seen one in this neighborhood
Aeolid Nudibranch found on the oyster raceways (800 micron) filter bag. Matanzas river. Size: 6mm x 1 mm. Water temperature 18.3 degrees C.Salinity 34 ppt
Juvenile, found in the rain near the type locality for this species. The closeup of a shell found nearby shows the reticulate pattern on the first whorl that is characteristic of Sonorelix.
Found in intertidal pools, during searches by R. Burn, A. Falconer and L. Altoff. Identified by R. Burn.
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.

Found diving in San Diego looks like arminia californica but has different colors
Fairly certain of ID but I realize there's precious little information out there on this cryptic aeolid. Help with positive ID would be appreciated. It seems like it might be a little large, given the size suggested by the blade of Zostera, but with so few observations, it's hardly definite. Note that user mbranfireun was my dive buddy and got some better photos of this specimen at https://www.inaturalist.org/observations/201611532
Feeding on sediment bottom. 15 ft deep.
Aeolid, 1.5cm long. Pink-peach body. Rhinophores smooth, long and joined at base. Cerata abundant with white tips and dark pink to red digestive glands with uneven, bumpy form.
Same observation as jonathan1232, same location, same date.
1mm. Shown on gloved finger for scale.
Found by Karen! Video showcasing big beating heart and what looks like a defensive cerata flare: https://flic.kr/p/2pB8Jt3. ~ 4-5mm.
Organized by retired State Park biologist Mark Faull, along with current State Park biologists and I found several shells and live snails of this poorly known species in Red Rock Canyon State Park. We hope to shed light on how closely it is related to other Sonorelix in the Mojave Desert. We were very glad to find that it still survives here, despite climate warming and drought.
The specimens were found in a tidepool in the high intertidal zone near 33*31'11''N 117*45'50'' W. The tide pool contained less than a foot of water at the time of observation (3:55PM), which was right before low tide.
Empty shell found within an empty shoulderband shell
Unknown non-native terrestrial snail
Resting in the upper inch of a woodrat nest in a rock crevice. Right across the Mohave River from a population of Victorville Shoulderband (which was unfortunately fenced). The photos show the precipitated cement dust from the nearby cement plant, which doesn't seem to harm the snails.

Close to the northern intersection of the Silver Leaf Loop and the Ponderosa Cutoff
Coolest find of the day by FAR was this incredible red branched dendronotid, also the largest nudibranch I’ve ever seen period. At least 1 foot long and absolutley breathtaking!! Surprisingly inshore as well! And actively feasting on coraline algae! One of my favorite experiences dock fouling so far!
Head of Scove Canyon, just off Sunrise Highway. Collected 12/10/16.
WOOO! About 4mm, 56ft deep, found by dive buddy Ayla Townsend on a midsize rock with a bunch of hydroids and several Flabellina on the backside of the rock eating other hydroids. Only realized later with the guidebook just how rare these little slugs appear to be.
This nudibranch looks like Truffle Dorid, Carminodoris bramale, which was found in Baja and could be introduced: https://www.inaturalist.org/observations/9332510

2nd record of this species! Found at a -.8ft low tide, at night, no wind, no waves

Found by @nudibitch! Second record of this species recorded, first is here: https://www.inaturalist.org/observations/90419664

undescribed sp first seen by @imlichentoday
found on kelp (https://www.inaturalist.org/observations/194171357)
but rearing when found, detached quickly
no wind, light to no surge, night, water temp 61 F, -0.8ft tide
found by @nudibitch
same individual as: https://www.inaturalist.org/observations/193347588
and
https://www.inaturalist.org/observations/193562037
same individual as yesterday (https://www.inaturalist.org/observations/193347588), still uncertain!
@jeffgoddard what do you think about this individual?
maybe a stretch of the imagination but:
3 large adults with egg masses covering numerous stalks of hydroids in the area
This observation is part of a long-term project examining plankton biodiversity in the nearshore waters around the Hakai Institute's Quadra Island ecological observatory. A COI DNA sequence from the organism has been deposited in the Barcode of Life Data System (BOLD). Photo license and credit belong to the Hakai Institute.
Apata pricei mating was located on sandy substrate at a depth of 45 feet. Lengths were not measured. Water temperature was 50 degrees F.
Apata cf pricei (Behrens et al 2022)???
“Body is translucent gray-white with a white opaque line running from the tip of the tail part way up the sides of the dorsum. 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
on inat this form has been ID as C rickettsi, per Terry Gosliner it is a different species
species 1 from the 2022 guide?
