Serripes groenlandicus, the Greenland cockle, is a common circumpolar bivalve found in up to 100m depth on a variety of substrates. It can grow up to 112mm. It is infaunal and usually inactive, but can use its foot to escape predators. The animal is a hermaphrodite, and after reaching maturity, the cockle spawns in March and April. Larvae are pelagic and settle in late summer. S. groenlandicus is a suspension feeder and can live up to 39 years. It is a main component in the diet of some walrus species as well as an important bycatch in the Atlantic surfclam (Mactromeris polynyma) fishery in Eastern Canada.
