Anomia (bivalve)

For other uses, see Anomia (disambiguation).

Anomia is a genus of saltwater clams, marine bivalve mollusks in the family Anomiidae. They are commonly known as jingle shells because when a handful of them are shaken they make a jingling sound,^[2] though some are also known as saddle oysters.^[3]

This genus first appeared in the Permian period of China, Italy, and Pakistan.^[4] Anomia species are common in both tropical and temperate oceans and live primarily attached to rock or other shells via a calcified byssus that extends through the lower valve.^[1] Anomia shells tend to take on the surface shape of what they are attached to; thus if an Anomia is attached to a scallop shell, the shell of the Anomia will also show ribbing.^[1] The species A. colombiana has been found in the La Frontera Formation of Boyacá, Cundinamarca and Huila of Colombia.^[5]
