Largest bivalve found on the south coast. It is fan-shaped with the tip embedded in sand or mud. The popular name ‘razor clam’ indicates the hazard these bivalves pose to bare-footed bathers. The species occurs gregariously and can be extremely abundant near low-tide mark in the South Australia gulfs. Shells in that area are usually colonised by diverse communities of plants and animals. The flesh of the razor clam can be eaten and was once sold in South Australia, although the size of the edible meat is trivial compared with the size of the shell.
