The Heterodonta are one of the major living clades of bivalves, with their earliest representatives appearing in the Ordovician. In the past, the living members of the clade were divided between the orders Veneroida and Myoida (the latter including burrowing forms with thin shells and reduced dentition) but molecular analyses have indicated that the myoidans are polyphyletic (Giribet & Wheeler 2002). Previous authors have also included the clades Carditoida and/or Anomalodesmata within their concept of Heterodonta but recent molecular analyses support their exclusion (Plazzi et al. 2011). The Hippuritoida are a fossil group known from the Silurian to the Cretaceous, primitively with a hinge of a few thick and amorphous teeth, that have been recognised as a third order of heterodonts.

Modern representatives of the Heterodonta include the Hiatellidae, a family of small, quadrate to trapezoidal, burrowing or nestling clams. They have more or less gaping valves and only one or two weak teeth in the hinge. The Galeommatoidea are burrowing clams with the shell commonly thin and more or less covered externally by the mantle. A number of species of this group live in association with other invertebrates, either attached to their body surface or within their burrows. The Thyasiridae are a group of thin-shelled clams with a distinct dorsal anterior depression near the hinge. Cyrenoida is a genus of thin-shelled, orbicular clams found in tropical brackish waters.
