Scientific classification
Kingdom:	Animalia
Phylum:	Mollusca
Class:	Bivalvia
Subclass:	Cryptodonta Neumayr, 1884
Orders
†Praecardioida Solemyoida

Cryptodonta is a subclass of the bivalves. It contains a single extant order, Solemyoida, while the Praecardioida are known only from fossils.

The valves of the shell are relatively thin and somewhat elongated. Unlike most other bivalves, species in this group have no hinge teeth on their shells. They have relatively primitive, "protobranchiate", gills.^[1]
