Clam shrimp are a taxon of bivalved branchiopod crustaceans that resemble the unrelated bivalved molluscs. They are extant, and known from the fossil record, from at least the Devonian period and perhaps before. They were originally classified in a single order Conchostraca, which later proved to be paraphyletic (artificial).

Come the first tide-ripples, moving, almost without sound, toward

Running along the narrow furrows of the shore, the rows of dead clam shells;”
