The species is commercially exploited and widely used for sushi in Japan.

However, in the Hokkaido region, it is called hokkigai ("northern clam").

Arctic surf clams grow to around 10 cm, and can live up to 30 years in shallow waters.

The foot of the clam is black when raw, but turns characteristically red when cooked.
