Venus is a genus of small to large saltwater clams in the family Veneridae, which is sometimes known as the Venus clams and their relatives. These are marine bivalve molluscs.
The genus Venus is named after Venus, the Roman goddess of love and sexuality.
However, some bivalves are still called Venus clams because they used to be in the genus Venus, though they are now placed in other genera: these include the species within the genus Mercenaria, and Pitar dione, the Venus shell described in sexual terms by Linnaeus.[1][2]
The genus is known from the Cretaceous to the recent periods (age range: from 136.4 Mya to now). Fossils shells have been found all over the world. About 20 extinct species are known.[3]
The family Veneridae contains over 400 known species, many of which are attractive and popular with shell-collectors.
The shells of venerids vary in shape, and include shells that are circular, triangular, and rectangular. Characteristically, Venus clams possess a porcelain-like inner shell layer, a complex tooth structure in the hinge, well-developed escutcheon and lunule, and a well-developed pallial sinus.
Veneridae colonize the sandy ocean bottom, and their populations are often dense and large. The Veneroida order typically has a folded gill structure which is well developed for filtering out small food particles.
The common names of clams in this genus often include the name Venus. A few species that still have "Venus" as part of their common name, but which are no longer in the genus Venus are:
