Emydidae (Latin emys (freshwater tortoise) + Ancient Greek εἶδος (eîdos, “appearance, resemblance”)) is a family of testudines (turtles) that includes close to 50 species in 10 genera.^[3][4] Members of this family are commonly called terrapins, pond turtles, or marsh turtles.^[1] Several species of Asian box turtles were formerly classified in the family; however, revised taxonomy has separated them to a different family (Geoemydidae). As currently defined, the Emydidae are entirely a Western Hemisphere family, with the exception of two species of pond turtle.
