Atlantic surf clam can be male or female, with no apparent physical difference.
Individuals release their reproductive cells simultaneously, and fertilization takes place in the water. Reproduction takes place mainly in July and August. Eggs become planktonic larvae, then grow into young miniature surf clams that burrow into the sand. Surf clams grow faster in cold water. They reach 9 cm in 5 or 6 years.
