Benthic; depth range 0 - 71 m (Ref. 101281). Temperate, preferred 11°C (Ref. 107945)
Eastern Pacific: Alaska to Baja California, Mexico.
Length at first maturity / Size / Weight / Age
Maturity: Lm ? range ? - ? cm Max length : 9.0 cm SHL male/unsexed; (Ref. 101478)
Forms reefs in the subtidal zone (Ref. 8593) and are also found in intertidal habitats (Ref. 104318). At high elevations, it is surrounded with mud flats and at low elevations with eel grass beds. Filter feeders which primarily feed on phytoplankton in the tidal waters (Ref. 101281).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
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.
