The Donacidae are prolific filter feeders and are an important part of coastal food chains where they occur. The family is sensitive to coastal industry such as dam-building and dredging.
Members of this family have asymmetric, elongated, compressed shells. The two siphons are short but are completely divided, and the foot is large. They are vigorous burrowers.
