Bivalvia | Veneroida
Environment / Climate / Range
Benthic; brackish; depth range 0 - 40 m (Ref. 95344). Polar
Pacific Ocean, Northern Atlantic, Mediterranean Sea and the Arctic.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm Max length : 3.8 cm SHL male/unsexed; (Ref. 95344); max. reported age: 10 years (Ref. 2823)
Occurs from the upper part of the intertidal down to the shallow subtidal zone (Ref. 76547). Circumboreal and panarctic. Buries shallow to 20 cm under muddy-sandy substrate, commonly in bays and estuaries (Refs. 95344, 95753). In the northern Baltic Sea, known to thrive in eutrophic conditions (Ref. 95752). It is infaunal on sand and eelgrass beds and epifaunal on eelgrass beds (Ref. 95819). Deposit and suspension feeder (Refs. 76547, 96470). Feeds from the surface of the sediment using their long siphons (Ref. 7882), and is a subsurface detritivore (Refs. 95728, 96470). 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 (Ref. 833).
