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).

Obscuring my tidepool observations in SF Bay Area counties

A sad decision. It may not help as much as other more tangible measures to stop the widespread taking/destruction of the local reefs that began in early 2020, but I don't want my personal iNat observations to assist tech-saavy foragers in any way. For now, this means Mollusks in San Francisco, Marin, San Mateo, Santa Cruz and Monterey counties only and genus Cancer crabs statewide.

Yes, it will now look like some tidepool creatures were seen miles inland. Sorry about that... If this affects your conservation project, and you need the precise locations of my observations, please message me privately, I'm happy to help.

Eastern Pacific Nudibranch News: Tritoniidae: 1) reinstated Tritonia exulsans and 2) New genus Tritonicula (affects 5 species)

Two recent taxon splits from a new paper from Tatiana Korshunova and Alexander Martynov (citation below). Action is only required on the first change.

Change #1: Tritonia exsulans has been reinstated - most recently it was included in Tritonia tetraquerta - and all iNat Observations WILL need to be re-reviewed since the ranges overlap. The super short, nonscientific answer on the visual difference/range is:

T. exsulans: Pink or salmon color, with white lines on the oral veil and between the dorsolateral appendages (range is California to British Columbia)
T. tetraquerta: Orange color, no white lines (range is Oregon to Kamchatka and Kuril Islands)

Change #2: Tritonicula: A new genus name for five species of Family Tritoniidae (Lamarck, 1809). I made the change to the new names in iNat this morning, and no manual changes are required (yay!). The new species names are:

Tritonicula bayeri (Ev. Marcus & Er. Marcus, 1967)
Tritonicula hamnerorum (Gosliner & Ghiselin, 1987)
Tritonicula myrakeenae (Bertsch & Osuna, 1986)
Tritonicula pickensi (Ev. Marcus & Er. Marcus, 1967)
Tritonicula wellsi (Er. Marcus, 1961)

Here's the full paper: https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0242103

Eastern Pacific Nudibranch News: Triopha catalinae AND Triopha modesta

New paper: https://link.springer.com/article/10.1007/s12526-020-01107-2 The external morphological difference is the shape of the lateral tubercles. Dendritic/short = T. modesta, Conical/rounded = T. catalinae. Close to all, if not 100%, of my SF Bay area observations are T. catalinae.

E. Pacific Nudibranch News: Six Deepwater Nudibranchs added to iNat (and CA Nudibranchs Guide)

Happy Holidays! Based on WoRMS (referencing Angel's 2018 paper https://biotaxa.org/Zootaxa/article/view/zootaxa.4526.4.1), I have added six new deepwater nudibranchs to iNat, four of which also were added to the CA Sea Slugs Guide. We can only hope that one will wash ashore someday - or perhaps an MBARI researcher will share a few photos!

They are:

  • Aeolidia libitinaria (Undertaker Nudibranch, found under whale bones)
  • Ziminella vrijenhoeki (Vrijenhoeki's Nudibranch - also under whale bones)
  • Tritonia nigritigris (Black Tiger Nudibranch)
  • Zeusia herculea (fanciful but no common name yet - I'm guessing this is a big one?)
  • Cuthona methana (Named re methane seeps, but no common name yet) - OREGON
  • Dendronotus claguei (Clague's Nudibranch) - MEXICO, south of the Gulf of CA

Here's a quick read about them from MBARI, with photos and a cool video.
@kueda will perhaps note some wordier similarities in the opening paragraph of the article with his own intro to the CA Sea Slugs Guide... ;-)

PS. We now have 180 sea slugs in the CA Guide!
