Reproduction is oviparous and dioecious. They are unable to fully withdraw their heads into their shells, instead drawing them to the side and folding them beneath the upper edge of their shells, hence are called African side-necked turtles. They are found in australasia. Snaked-neck Turtle - Turtles---Austro-South American Side-necked Turtles . Snaked-neck Turtle - Turtles---Austro-South American Side-necked Turtles .

"Evolution and Zoogeography of Australian freshwater turtles". Gordos, M. A.; Franklin, C. E. & Limpus, C. J. So, this species is on the larger end of the spectrum for pet turtles. [15] The subfamilies within Chelidae show the monophyly of the majority of the South American species and all the Australian species, with the far more ancient Hydromedusa as sister taxon to both these other groups. Skull emargination provides room and anchorage for the jaw muscles. The Austro-South American Side-necked Turtles of the family Chelidae are one of the three living families of the turtle suborder Pleurodira. Within the Pleurodira, three living families are represented: Chelidae, also known as the Austro-South American side-necked turtles, the Pelomedusidae, also known as the African mud terrapins, and the Podocnemididae, also known as the American side-neck river turtles.
