Australian Freshwater Turtles Australia is the driest of vegetated continents. Combined discharge of all of our rivers equals that of the Missouri River of North America, a tributary of the Mississippi. Little wonder that the diversity of freshwater turtles in Australia does not compare well with that of the Americas or Asia. However, like the marsupials, Australia’s freshwater turtle fauna is spectacularly different from a northern hemisphere perspective.All but one species belongs to the family Chelidae, a group of side-necked turtles found elsewhere only in South America, New Guinea and the small islands of Roti and Timor. Among them are forms with the longest necks of any turtle, the rarest turtle in the world, and the only species known to nest underwater. Many have yet to be described. The enigmatic Pig-Nosed Turtle is the sole surviving member of its family (Carettochelydidae), unique to the Australasian region, but of global interest. |
