Short description Morphology
The shell is strong, heavy, and generally smooth though sculptured with fine concentric growth lines; beak nearly central; ligament obvious, elongate, set in deep groove; periostracum shiny, greenish to brownish; shell pale buff to dark chocolate, occasionally marked with brown or purple-brown bands.
Maximum depth from Ref. 101605. Filter-feeder, feeds on phyto- and zooplankton, bacteria and detritus. Its predators may include crabs, snails, gulls, sea otters, sharks, rays and some fishes (Ref. 101635).
Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Gametogenesis begins in March or April and ripe gametes first appear in April and May. Gonadal development proceeds rapidly in June and July; spawning begins in late July or early August and continues to the end of November. Discharge of gametes appears to take place when there is a fair rise in water temperature. Males usually spawn first and their release of gametes stimulates the females to spawn. Spawning may occur several times during the season since only a portion of the gametes ripen at one time. (Ref. 101635).
