Quick Facts About Saltwater Crocodiles

The Saltwater Crocodile in Australia’s Northern Territory is the largest reptile in the world, and has remained one of the deadliest predators for more than 100 million years. Found across the wetlands and areas in north Australia, including Kakadu, Broome, and the top end of the Northern Territory, these magnificent beasts can reach a whopping 7m in length, though most adult males come in at around 5m. There are thought to be around 200,000 Saltwater Crocodiles in Australia, with the most found in the areas surrounding Darwin and the Mary River.

Over the years, they have been hunted for their skins and have almost been brought to extinction on a number of occasions. In fact, in the 1950s, numbers became so low that hunters had trouble even finding any in the first place. Since then, conservation efforts have been put in place to ensure the crocs can flourish and breed without the danger of hunters. As a result, their numbers have increased drastically, and they now form an important part of the ecosystem in Northern Australia.

Quick Facts About Saltwater Crocs:

These crocs can live up to 70 years and usually grow to around 5m, although the largest of their kind was found in the 1980s near the Mary River and measured in at an impressive 20 feet.
When they’re born, baby Saltwater Crocodiles can weigh as little as 60g. This all changes when they reach adulthood, though, as large males can often weigh in close to 1,000kg.

Saltwater Crocodiles breed during the wet season in the Northern Territory, and females can lay up to 50 eggs, which they build nests for along the nearby river banks. The eggs incubate for around 3 months before hatching, and it’s the temperature of the nest that determines what sex the offspring will be. Amazingly, only 1% of hatchlings survive into adulthood.

With around 68 sharp teeth, you don’t want to get on the wrong side of a croc. Larger members of the species can exert two tonnes of pressure with a single bite and, if their teeth break off in the process, they simply grow some new gnashers in their place.

Though crocodiles often strike their prey from underwater, they can’t swallow below the surface, so they have to lift up their prey in order to eat.

Saltwater Crocodiles can reach speeds of 10km per hour in water and can run on land up to 11km in short, sharp bursts.
