Scientific classification
Kingdom:	Animalia
Phylum:	Mollusca
Class:	Bivalvia
Subclass:	Autobranchia
Infraclass:	Heteroconchia; J. E. Gray, 1854
Subterclasses
	Archiheterodonta; Euheterodonta; Palaeoheterodonta; Heterodonta;

Heteroconchia is a taxonomic infraclass of diverse bivalve molluscs, belonging to the subclass Autobranchia.

This infraclass includes the cockles, Venus clams, the freshwater mussels, brooch clams, as well as Heterodonta and Archiheterodonta.

Description

These bivalves are distinguished by having the two halves of the shell equally sized (i.e., they are equivalved) and having a few cardinal teeth separated from a number of long lateral teeth. Their shells lack a nacreous layer, and the gills are lamellibranch in form. Most species have a siphon.
