Apata cf. pricei of Behrens et al. (2022), Coleman Beach, Sonoma Co., CA, 29 Apr 2009. 15mm length.

CASIZ 181322 (as Flabellina)

Photos by Gary R. McDonald (@mcduck) of a specimen I found in the low rocky intertidal in the morning, collected, kept cool and then dropped off in Aromas, CA for Gary to photograph using his home aquarium setup, which he did that evening. Gary later relaxed and preserved the specimen and sent it to the Invertebrate Zoology collection at the California Academy of Sciences. Scanned from 35 mm slides.

Brenna Green (@lemurdillo, who had joined me for the low tide) and I were looking at this specimen in the field after I found it and were perplexed by its identity. We decided it was closest to Flabellina pricei (now Apata pricei), but the differences in color from the few other specimens of F. pricei I had seen, warranted its collection, and I labelled the specimen as Flabellina (pricei?).

Description

SUPER rare! This Calliostoma tricolor only has one band on the front part of the last section of its last whorl while they normally have multiple. I’ve seen hundreds of their shells and this is my first time seeing this. I would imagine it was caused by a crab attack damaging the mantle, causing the shell to grow strangely. In the last two pictures you can see it compared to what a normal shell would look like. Maybe a one in ten thousand chance find?
