Nudibranch Common Names

I am synonymizing all Eastern Pacific nudibranch English common names with the new edition: Behrens et al, "Nudibranchs and Sea Slugs of the Eastern Pacific," 2022. This means that some of your old faves (Hermissenda crassicornis, Abronia abronica, Acanthodoris lutea, etc) will have slightly different, possibly new-to-you primary common names. Yes, your old favorite names are still retained. Ah, change...

E. Pacific Nudibranch News: Now available: New edition of Behrens, et al Nudibranchs and Sea Slugs of the Eastern Pacific

It's been 17 years since the last edition, and the new "Nudibranch Bible" for the West Coast of the US, Canada and Mexico is terrific!

Softcover is available now at MolaMarine.com or Amazon.
Link: https://www.molamarine.com/

Description: This complete and colorful guide covers all of the 370+ species of shallow-water sea slugs known to occur from Alaska to Central America. In addition to size, range, and habitat descriptions, it also provides information on color variations, eggs, and convenient tips on how to distinguish them from similar species. Richly illustrated with color photos contributed by over 50 of the best "nudie" photographers on the west coast, it is an essential refererence for divers, beachcombers, underwater photographers, and anyone else with an interest in this fascinating group.

Enjoy!

E. Pacific Nudibranch News - Long's Aeolid found in Channel Islands

I've been travelling so apologies in advance if you already know this. A rare and beautiful Mexican nudibranch -- Long's Aeolid (Cuthona longi) -- was photographed in the Channel Islands on May 27 by Douglas Klug. Terrific photos may be seen on Flickr: https://flic.kr/p/2nr1QR3

I added this species to the California Sea Slug Guide: https://www.inaturalist.org/guides/40

E. Pacific Nudibranch News - Goodbye Orienthella, Welcome Back Coryphella

Scientific name changes following a recent paper for a number of Eastern Pacific nudibranch species:

1) Three-lined Aeolid (old: Orienthella trilineata) is now Coryphella trilineata.

2) Cooper's Aeolid (old: Orienthella cooperi) is now Coryphella cooperi.

3) Predaceous Aeolis (old: Himatina trophina) is now Coryphella trophina.

4) Coryphella pseudoverrucosa is no longer a separate species. It is now considered a junior subjective synonym of Coryphella verrucosa (Red-fingered Aeolis).

You do not have to go back and rename your Observations, all of these changes happened automatically. Genus Orienthella is now Inactive on iNat and should not be used for IDs.

E. Pacific Nudibranch News - New Name for Janna's Dorid: Genus Knoutsodonta now Genus Atalodoris

Since iNat follows WoRMS, and this new genus has been accepted by WoRMS, Genus Knoutsodonta - Hallas & Gosliner, 2015 is now Genus Atalodoris - Iredale & O'Donoghue, 1923. Citation: https://www.marinespecies.org/aphia.php?p=taxdetails&id=597122

Good news, do nothing!
If you have old Observations of Janna's Dorid, the name has automatically been changed to Atalodoris jannae and you don't need to do anything. The same is true for all the observations of the 15 other species in the genus.

The common name remains the same.

Genus Knoutsodonta is now Inactive and should not be used for Observation IDs. Citation: https://www.marinespecies.org/aphia.php?p=taxdetails&id=845525)

For now, I have included the undescribed Knoutsodonta sp-a in the genus name change to Atalodoris, though this may need further review.

New: The Pot Fouling Project (and already a new snail!)

One day into the new project, already something interesting. A first on iNat for the SF Bay Area: Southern Flatcoil Snail. This snail was in a plant nursery in Cupertino, Santa Clara County, CA: https://www.inaturalist.org/observations/101369553

https://www.inaturalist.org/projects/the-pot-fouling-project

Please join The Pot Fouling Project if you are interested in land snails and slugs, mushrooms and other fungi, salamanders and newts, millipedes, centipedes, spiders, insects, terrestrial worms, etc. Anything that lives under a human-made garden container is fair game to add to this project. Urban or rural as long as it's under something, so check out nurseries, public gardens, etc. And perhaps it will help scientists track invasive species too, so yay for that.

Pots (and nurseries) remind me a little of the man-made marinas and harbors where I go dock-fouling; they might provide "safe harbor" for non-native species to establish themselves through inadvertent introduction. AKA Ground Zero.

Able to help on the snail?: Rookie question: Southern Flatcoils are widespread across the Southern US, including Southern California, but I have yet to find a record of them in the San Francisco Bay Area, which strikes me as weird. They do not appear in Roth & Sadeghian's checklist, but I can't imagine this is really the first record of them here. If you are a California land snail expert - and I'm looking very hopefully at you @jannvendetti @cedric_lee @pliffgrieff @thomaseverest @tlawson @susanhewitt @finatic @oksnaillaboratory - could you please weigh in on this if you have a chance?

E. Pacific Nudibranch News: Two New-to-Science Nudibranchs Found on the California Coast

Not one, but TWO new-to-science nudibranchs were found this summer in California. Both were spotted by iNaturalist community scientists (Luan Roberts and Siena McKim).
