The Superfamily Testudinoidea is further organized into finer groupings including:
- Family (5): Adocidae · Bataguridae · Chelydridae · Emydidae · Testudinidae
Families
Adocidae
Bataguridae
Geoemydidae (formerly known as Bataguridae) is the largest and most diverse family[] in the order Testudines (turtles) with about 70 species. It includes the Eurasian pond and river turtles and Neotropical wood turtles. [more]
Chelydridae
Chelydridae is a family of turtles which has seven extinct and two extant genera. The extant genera are Chelydra the snapping turtles, and its larger relative Macrochelys, of which the Alligator Snapping Turtle (Macrochelys temminckii) is the only species. Both are endemic to the Western Hemisphere. The extinct genera are Acherontemys, Chelydrops, Chelydropsis, Emarginachelys, Macrocephalochelys, Planiplastron, and Protochelydra. [more]
Emydidae
Emydidae, commonly called the pond turtles or marsh turtles, is a family of turtles. Previously, several species of Asian box turtle were classified in the family. However, revised taxonomy has separated them to a different family. Now, Emydidae, with the exception of two species of pond turtle, is entirely a Western Hemisphere family. The family Emydidae includes close to 50 species in 10 genera. [more]
Testudinidae
Tortoises (, Testudinidae) are a family of land-dwelling reptiles of the order of turtles (Testudines). Like their marine cousins, the sea turtles, tortoises are shielded from predators by a shell. The top part of the shell is the carapace, the underside is the plastron, and the two are connected by the bridge. The tortoise has both an endoskeleton and an exoskeleton. Tortoises can vary in size from a few centimeters to two meters. Tortoises are usually diurnal animals with tendencies to be crepuscular depending on the ambient temperatures. They are generally reclusive animals. [more]
At least 198 species and subspecies belong to the Family Testudinidae.
