NOT SUBBED In the freshwater rivers and lakes of central and eastern Australia you might come across a huge broad-snouted freshwater crocodile (Paludirex). It has large plates of bone underneath its skin called osteoderms that act as armour from other predators, including its own kind. Its huge teeth means it's able to devour huge megafauna coming to the water’s edge for a drink. This species live much further inland than the crocs that will outlive it for another 40,000 years, even as far south as Kati Thanda, or Lake Eyre.
