CONT: In dense groupings, bivalve mollusks, including oysters, scallops, quahogs, and soft-shell clams (Mya arenaria), form a habitat type known as shellfish beds. ... Each species of bed-forming shellfish has different habitat requirements, which means that shellfish beds can be found in a range of depths, salinities, or substrates (surfaces, such as sand, rock, or mud). ... Many other species, such as scallops, soft-shell clams, and surf clams, do not attach to each other but their dense aggregations are nevertheless referred to as shellfish beds.
