Heterodonta is a taxonomic subclass of saltwater clams, marine bivalve molluscs. This subclass includes the edible clams, the cockles and the Venus clams.[1]
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.[2]
Orders
This subclass contains four extinct orders, five orders of living bivalves, and a group of as yet unassigned Euheterodonta:
- Order †Cycloconchidae
- Order †Hippuritoida (rudists)
- Order †Lyrodesmatidae
- Order †Redoniidae
2010 Taxonomy
In 2010, a new proposed classification system for the Bivalvia was published in by Bieler, Carter & Coan, revising the classification of the Bivalvia, including the subclass Heterodonta.[3]
