Crocodiles in Kakadu

Kakadu is home to both saltwater and freshwater crocodiles. These ancient reptiles have been living in this region for millions of years and have adapted to survive in its unique environment. The crocodiles in Kakadu play a crucial role in the ecosystem and are considered apex predators.

Diet of crocodiles

Crocodiles are opportunistic feeders and have a diverse diet. While their diet may vary depending on the availability of prey, crocodiles in Kakadu primarily feed on fish, crustaceans, birds, and small mammals.


Fish make up a significant portion of a crocodile’s diet in Kakadu. The park is known for its rich aquatic biodiversity, with numerous freshwater rivers and billabongs that are teeming with fish. Crocodiles often lie in wait near the water’s edge and ambush unsuspecting fish that come close to the surface.


In addition to fish, crocodiles also feed on crustaceans such as crabs and prawns. These small marine creatures provide a valuable source of protein for the crocodiles, especially during the dry season when other food sources may be scarce.


Crocodiles in Kakadu are known to ambush and feed on various bird species. They patiently wait near the water, concealed by reeds or vegetation, and strike at the opportune moment. Birds that come to drink or feed near the water’s edge become easy targets for these stealthy predators.
