Soft shell clams (Mya arenaria) are found in protected coastal embayments from Labrador to North Carolina. Soft shell clams are found on Prince Edward Island throughout bays and estuaries. The outer shell of the soft shell clam has a chalky white appearance. The surface of the shell is covered with somewhat elliptical markings, some more pronounced than others. These are the annual growth marks or rings which can be used to aid in aging clams. In general, the shell reaches a maximum size of about 10cm in length but some have been reported to exceed 15cm. In order to be harvested Prince Edward Island soft shell clams must at least 5 cm in size.
