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?).
