Members of the Cucullaeidae are large, heavy shells closely related to the Arcidae. They differ in the structure of the hinge, which in the Cucullaeidae has small central teeth and a few larger, elongate teeth at both ends. Internally, there is a flange to which the posterior adductor muscle is attached. There is only one species of the family occurring in Australia.
