Distant reptilian cousins, or scaly siblings?

Darwin is home to some of Australia’s most extreme wildlife. With poisonous spiders, enormous snakes, large insects and of course, crocodiles.

Saltwater crocodiles populate the waters of Darwin. They live both in the ocean and in the creeks and waterways.

But what about alligators? Are there any alligators anywhere in Australia?

Well, no. But they are related and come from the same reptilian family tree. So let’s look at the differences between these two prehistoric beasts!

Crocs vs Alligators

They are native to different parts of the world: Alligators live in the US, and are found in some areas of China. In the US, you’d find them in Louisiana and Florida.

Although crocodiles are found in America too, they’re far more widespread than the alligator population. They’re found in Africa and Asia as well as Northern Australia.

So if you come across a huge reptile in Darwin and you’re not sure what it is, then it is probably a crocodile. But we wouldn’t recommend sticking around to find out.

Similarities between crocs and alligators

You’ll never find alligators in Darwin because they simply never made it to Australia! They are similar creatures and probably evolved from the same species millions of years ago. We know this, not only because of their similar appearance, but also their similarities in adaptable features.

They can run fast on land

Both can run on land and move quickly over short distances.

They can’t move for long distances as their land speed doesn’t last long enough – but they can get up to 17 or 18 km/h.

They can hold their breath for a long time

They spend a really long time under the water! That means crocs and alligators can hold their breath for a long time underwater. This is a very helpful behaviour for hunting their prey.

They both have excellent night vision

Both alligators and crocs are nocturnal hunters. Both crocs and gators have eyes that are packed with cells called ‘rods.’ These ‘rods’ help them to see in the dark, in lower light conditions.

Spot the difference…

What are the differences between alligators and crocodiles?

Crocs have a long snout. It’s in the shape of a V. Gators, on the other hand, have a short, U-shaped snout.
Crocs show their teeth, even when they have their mouths closed. Gators will hide their teeth.
Saltwater crocodiles are the biggest reptiles on Earth. They grow up to around 6 metres. Alligators are smaller and they’ll grow up to 4 meters.

Crocodiles in Darwin

Darwin is home to both saltwater and freshwater crocodiles.

Normally, freshwater crocodiles are small and shy, but saltwater crocs are predators – and they can be very territorial! Saltwater crocs are found in floodplains and rivers as well as coastal waters. Listen to the locals, when they say ‘where there’s water, just assume there’s a croc’. It’s the best safety advice when it comes to crocs!

See a croc, safely

Crocodiles are one of the most memorable creatures you’ll ever see in the wild. With enormous bodies, scaly camouflage, and their eerie eyes…your trip to Australia wouldn’t be complete without seeing a croc.

While it’s important to keep croc-safe, that doesn’t mean you have to miss out! Here’s how you can see crocs in Darwin:
