Anteaeolidiella chromosoma (Cockerell & Eliot, 1905)

Well at least a couple of us are able to get wet during this pandemiic. Phil Garner and Merry Passage in Southern California own their own boat so they can escape this craziness and get in an occasional dive.

On one recent lucky sojourn Phil found this not-so-common teeny tiny specimen during a "Dock" dive (under the boat). Only 4 mm long, Phil sent me this photo unsure of what it was. I was glad to see that the text in Eastern Pacific Nudibranchs described this little guy perfectly. Maybe a first.

The rhinophores are reddish with white tips. The body is dull orange. The midline is clear of cerata and bears irregular small patches of white. Perfect.

Like other members of the Aeolididae, it feeds on sea anemones.

This uncommon little puppy, whose generic placement has gone from the genus Spurilla to Aeolidia to Anteaeolidia, is a nice find.

Phil on the hunt!
After free diving for a year I was scuba certified in 1989. Most of my dives have been on the reefs and wrecks around the Palos Verdes Peninsula. In 2012 I published my first book, Diving the Palos Verdes Peninsula, a guide to 25 sites from Redondo Beach to San Pedro. Most weekends I can be found diving with my fiance Merry Passage and friend Kevin Lee in search of uncommon nudibranchs, the smaller the better. My favorite dive destinations have been Anilao and Vancouver Island for the varied marine life. Another dive site I frequent is the Morro Bay T-Pier. When conditions are favorable we have been able to identify close to two dozen species on a dive there.

Merry, Kevin and I try to dive offshore reefs around Palos Verdes every weekend.

I shoot with a Nikon D850 camera in a Subal housing, 105mm lens, and Ikelite DS160 strobes

Merry Passage

Merry Passage worked as a genetics research scientist at Harbor UCLA for three decades. After retiring she has used her degrees from Arizona State University and laboratory experience as an aid to scuba diving. She spends countless hours researching many of the animals we find underwater. Her home office is filled with binders and identification books from algae to whales.
