Emydidae
Emydidae is a family of testudines (turtles) which includes close to 50 species in 10 genera. Members of this family are commonly called terrapins, pond turtles, or marsh turtles. Several species of Asian box turtle were formerly classified in the family; however, revised taxonomy has separated them to a different family. As currently defined, Emydidae is entirely a Western Hemisphere family, with the exception of two species of pond turtle.
