Surf Clams

Family Mactridae

Max Size: Up to 17 cm (7 in) but typically <2.5 cm (1 in)
Habitat: Intertidal zones, in mud/silt, sand, other loose sediments
Diet: Plankton
Fun Facts:

  • Use their strong foot to burrow in the sediment
  • Easy to distinguish from mussels by larger width of the shell relative to the hinge
  • Their ability to dig makes them better suited to soft sediment habitats than other bivalves
