Myoidea

Specimen of Mya truncata with protruded siphons, photographed by Claude Nozères.


Belongs within: Neoheterodontei.
Contains: Corbula.

The Myoidea, soft-shell clams, are a group of infaunal bivalves first recorded from the Upper Jurassic. Within the group, the Myidae have the shells elongate and chalky with a wide posterior gape. Corbulidae have sturdier shells with inequilateral valves and usually with a resilifer in one valve.
