What does it look like?Description: One of the largest freshwater turtles in the world. It has a camouflaged, ridged upper shell, a large head and powerful, hooked, beak-like jaws, which, together with its thick, scaly skin and oversized claws, all contribute to its primitive look and set it apart from other freshwater turtles. The three large, pronounced ridges running down the length of the dark brown to blackish shell somewhat resemble those on the back of an alligator. The tail is almost as long as the shell itself and, together with the chin, throat and neck, is coated with long, pointed tubercles. Habitat: Generally found in the deep water of large rivers, canals, lakes and swamps, though hatchlings and juveniles usually live in small streams. Breeding: Nests are dug at least 50 metres from the water’s edge, and a clutch containing anything between 8 and 52 eggs may be laid. Incubation lasts 100 to 140 days and most hatchlings emerge in autumn. The sex of the young is determined by incubation temperature; high and low temperatures yield more females and moderate temperatures yield more males. Sexual maturity is attained between 11 and 13 years of age.
