Anomiidae is a family of saltwater clams, marine bivalve molluscs related to scallops and oysters, and known as anomiids. It contains seven genera.
The family is known by several common names, including jingle shells, mermaid's toenails, and sa ...

/ref> ''Anomia'' species are common in both tropical and temperate oceans and live primarily attached to rock or other shells via a calcified byssus
A byssus () is a bundle of filaments secreted by many species of bivalve mollusc that function to attach the mollusc to a solid surface. Species from several families of clams have a byssus, including pen shells (Pinnidae), true mussels (Mytilid ...

Reassigned species
As ''Anomia'' was erected very early in paleontology, several species have been reassigned; most of them are now recognized as brachiopods
Brachiopods (), phylum Brachiopoda, are a phylum of trochozoan animals that have hard "valves" (shells) on the upper and lower surfaces, unlike the left and right arrangement in bivalve molluscs. Brachiopod valves are hinged at the rear end, whi ...
