The Gentle Giant of Australia: Freshwater Crocodile

You know, they say nothing prepares you for face-to-face contact with a crocodile.

But when I first saw a pair of eyes break the surface of a calm river in Northern Australia, the sensation was more awe than fear. Thus began my encounters with the Freshwater Crocodile.

Freshie Up Close – Describing the Freshwater Crocodile

The Australian Freshwater Crocodile, affectionately known as ‘Freshie’, isn’t your typical crocodile.

Its proper name is Johnstone’s Crocodile (Crocodylus Johnstoni). The species was named after Robert Johnstone, who sent the first specimen to the British Museum.

They are generally smaller and less aggressive than their saltwater cousins. Freshies grow up to 2-3 meters long, and their slim, sleek body is topped off with long, narrow snout.

Freshwater Crocodiles are generally more laid-back than their saltwater relatives. They’re known to be quite shy, often retreating into the water when disturbed.

But don’t let their calm demeanour fool you; they are efficient predators, feeding mostly on insects, fish, and crustaceans.

Freshies have a special fondness for sunbathing. Can you imagine, a crocodile with a sun tan?

Spotting a Freshie – Distribution and Habitat

You’ll find Freshies across northern Australia, from the Kimberley region in Western Australia to the upper reaches of Queensland.

They favour freshwater habitats like rivers, billabongs, and wetlands. If you’re lucky, you might spot one sunning itself on a river bank!

They do this to regulate their body temperature. These sunbathing sessions are a classic Freshie sight!

If you want to be certain to sport one, jump in your 4WD and drive to Windjana Gorge.

The Circle of Life – Freshwater Crocodile Reproduction

During the breeding season, which usually starts in the dry season (around May to September), males court females through a series of behaviours such as snout rubbing and gentle biting.

Females then lay 4 to 20 eggs in a nest, usually a mound of sand or vegetation, close to the water’s edge.

After a 2 to 3 months incubation period, the babies hatch. Interestingly, the sex of the hatchlings is determined by the temperature of the nest, with higher temperatures more likely to produce females.

Once the babies hatch, the mother carries them gently in her mouth to the water. It’s a touching sight, showcasing a softer side to these prehistoric creatures!

More Facts about the Freshwater Crocodile

Night Owls

Despite their love for sunbathing, Freshwater Crocodiles are actually nocturnal predators. They do most of their hunting at night, utilising their excellent night vision and keen sense of hearing.

Speedy Swimmers

Don’t be fooled by their relaxed sunbathing. Freshies are swift and agile in the water. They can reach impressive speeds when swimming, especially when they feel threatened and need to make a quick getaway.

A Toothful Smile

Freshwater Crocodiles have an impressive set of chompers, boasting around 68-72 teeth. When a tooth wears out, it gets replaced. They can go through thousands of teeth in their lifetime!

Miniature Masters

When Freshie hatchlings emerge from their eggs, they’re only about 7-12 cm long but are perfect miniature replicas of the adults. Even at this tender age, they’re fully capable of hunting their own food.

An Ancient Lineage

Crocodiles, including Freshies, are essentially living fossils. They’ve existed for around 200 million years and have outlived the dinosaurs.

Their body design has remained largely unchanged over this vast span of time, a testament to their remarkable adaptability and survival skills.

Our Encounters with Freshies

The Shy Sunbather at Cobbold Gorge

It was a beautiful day as we strolled through the stunning landscapes of Cobbold Gorge. Suddenly, we spotted a Freshwater Crocodile on the banks of the river.

It was as if it was posing for us, basking in the sun, when it realised it had an audience. The croc was shy, quickly sliding into the water, leaving us with a ripple and a memory.

The Bat Hunter of Mataranka

Our journey also led us to Mataranka, where we had another remarkable encounter.

As dusk fell, we watched a Freshie hunting bats in the twilight. The scene was incredible, showing us a different side to these creatures, proving they aren’t just calm sunbathers, but proficient hunters too.

The Roadside Rendezvous on Gibb River Road

Lastly, our travels took us along the infamous Gibb River Road.

But the highlight was our stop at Windjana Gorge. Here, we spotted several Freshies lounging lazily by the water’s edge. Their calm presence added a surreal touch to the wild and rugged landscape.

Is Freshwater Crocodile endangered?

Freshwater Crocodiles are considered of Least Concern by the IUCN. Despite threats from invasive species and habitat loss, their population is relatively stable. But this doesn’t mean they don’t need our respect and protection.

Visiting their habitat, I couldn’t help but feel a sense of responsibility. These ancient reptiles, the gentle giants of Australia’s waterways, are counting on us to keep their homes safe.
