Quick Summary

The soft-shell clam, scientifically known as Mya arenaria, is a type of mollusk characterized by its elongated shape and thin, fragile shell. These clams are commonly found on the east coast of North America and are often eaten steamed.1

Mollusks, as a phylum, are diverse soft-bodied invertebrates, many of which are enclosed in a calcium carbonate shell. This phylum includes a wide array of creatures, such as snails, oysters, squids, and various types of clams. Clams, specifically, are bivalve mollusks, meaning they possess a shell divided into two sections. The soft-shell clam is one of many edible clam species, often used in soups and chowders.23
