Southeast Pacific, Southwest Atlantic and the Antarctic. Subtropical to polar.
It is found on various substrates including rocky walls, and macroalgae covered with hydrozoans from depths of 1 to 160 m (Ref. 87801). Members of the order Nudibranchia are simultaneous hermaphrodites. Mating behavior: Both individuals darts their penis toward each other to induce one to act as a male and the other as the female. The victorious one to penetrate the body wall is the dominant male. Life cycle: Eggs are deposited on a substratum where they develop and hatch into (planktonic) vestigial veliger larval stage and further grow as adults (Ref. 833).
