7 genera, see text Anomiidae is a family of saltwater clams, marine bivalve molluscs related to scallops and oysters, and known as anomiids.

The family is known by several common names, including jingle shells, mermaid's toenails, and saddle oysters.

Anomiids have extremely thin, translucent, paper-like shells.

The flesh of members of this family is unpleasantly bitter and is not eaten.

However, industrial uses of the shell include manufacture into, or as part of, glue, chalk, paint, shellac and solder.
