Adults feed mainly on fish but may also eat amphibians, reptiles and small mammals (2). Very little else is known about the natural history of this species in the wild, but females do appear to build mound-nests constructed from scraped-up plant debris mixed with mud (3). In captivity, these crocodiles breed during the wet season (April to May), laying between 20 - 50 eggs which are then guarded until they hatch (4). After incubation, the female will assist her young as they break out of their eggs and then carry the hatchlings to the water in her jaws (5).
