It is heavily exploited commercially, stocks are dwindling in southernmost part or range. Consumed boiled in juices, marinated, grilled with rice, or in a number of different local dishes. Canned industrially (Ref. 271). Minimum depth from Ref. 104365. It is attached by byssus onto hard substrates, common in high-energy rocky coasts (Ref. 271). Feeds primarily on detritus (Ref. 114808).

Livscykel och parningsbeteende Könsmognad | Reproduktion | Lek | Ägg | Fekunditet | Larver

Members of the class Bivalvia are mostly gonochoric, some are protandric hermaphrodites. Life cycle: Embryos develop into free-swimming trocophore larvae, succeeded by the bivalve veliger, resembling a miniature clam.
