The saw-shelled turtle (Myuchelys latisternum) is a species of turtle in the Chelidae family endemic to Australia, ranging along rivers and streams and connected swamps and lagoons from coastal Cape York Peninsula to northern New South Wales, with populations also noted as far south as Newcastle - (Williams River Catchment site of the former Tilligra Dam).

[6] The combination Wollumbinia latisternum (Gray, 1867) Wells, 2007, was declared unpublished and hence unavailable for use by Fritz & Havaš 2007.

[10] They can have three to four clutches in one season of 9 to 20 eggs which hatch before winter in about 60 days, with the incubation period shortened in southern regions.

It feeds on fish, tadpoles, frogs, bivalves, crustaceans, snails, carrion, and aquatic and terrestrial insects.

It is also one of the few native Australian animals successful in preying on the introduced and very poisonous cane toad (Rhinella marina) which is lethal to many freshwater turtles.

[11] Myuchelys latisternum is most often located in headwaters or tributaries of larger rivers in creeks, waterholes, dams, and lakes.

However they are a highly adaptable species and have been seen in a variety of landscapes such as savannah woodlands, tropical rainforest, farmland, and semi-urban environments.
