Chelidae is one of three living families of the turtle suborder Pleurodira, and are commonly called Austro-South American side-neck turtles. The family is distributed in Australia, New Guinea, parts of Indonesia, and throughout most of South America.

It is a large family of turtles, and its fossil history goes back to the Cretaceous. The family Chelidae has about 60 living species in about twenty genera. [1]

Molecular evidence suggests that the Chelidae can be further divided into three subfamilies: the Hydromedusinae, containing only the genus Hydromedusa; the Chelidinae, containing all other South American chelids; and the Chelodininae, containing both the short- and long-neck species of Australia and New Guinea. This taxonomic relationship has ...
