It is found on rocky substrates where it is attached to boulders, cobbles, pebbles, and epibiotic on bivalves, Aulacomya atra and the barnacle Austromegabalanus psittacus (Ref. 87801), and in forests of Macrocystis pyrifera (Ref. 92889).

This is a hermaphrotic species. Egg masses are composed of 29 egg capsules, each one containing up to 721 eggs, and are retained beneath the female shell. Only a few of the eggs develop and the others serve as nutritional eggs (Ref. 87801). It displays poecilogonony as its reproductive strategy (Ref. 99837).
