Short-term effects of commercial clam (Mya arenaria L.) and worm (Glycera dibranchiata Ehlers) harvesting on survival and growth of juveniles of the shoft-shell clam. Journal of Shellfish Research 20(3):1145–1157. Description Mya arenaria is a large long-lived bivalve. The shell is dirty white or fawn in colour with a fawn or light yellow periostracum. Large specimens may reach 12 -15 cm in length. (Blundon and Kennedy, 1982; Smith et al., 1999). As Mya increases in size, it becomes prey to infaunal predators such as naticid gastropods (Edwards and Hubner, 1977), nemertean worms (Bourque et al., 2001), and other species that are adept at removing it from sediments and consuming it at the surface such as large decapod crustaceans The soft-shell clam (Mya arenaria) generally is believed (not unanimously) to have been introduced with plantings of Crassostrea virginica in San Francisco Bay around 1807, and then migrated northward.
