This side-gill slug (Pleurobranchidae) likely lost its dorsum in the process of collection, but the only large species present at this depth of about 123m is Pleurobranchia californica McFarland, 1966, sometimes known as the California sea slug. This voracious predator feeds on various marine animals, including various slugs (including its own species), squid eggs, polychaetes, some crustaceans, and some fishes.
