Estaurine Crocodiles- 15 Terrifyingly Awesome Facts

Estaurine crocodiles are pretty incredible animals!

As the largest living reptiles on the planet, these apex predators are amazing and terrifying in equal part.

Here’s 15 terrifyingly awesome facts about Estaurine Crocodiles that will have you asking “really?”

They Can’t Sweat

Although we may be sweating bucketloads when we spot one (after all it’s natural instinct), these giant reptiles can’t actually sweat themselves!

Although crocodiles prefer to be warm, the tropics can often be a little too much for them! In the Summer months they often cool down by sitting on the river banks and opening their mouths.

Their Gender Is Decided By Incubation Temperature

The gender of Estaurine Crocodiles is decided by the temperature in which the egg is incubated!

Crocodile eggs have a painfully long incubation period of around 80 days and gender is decided around three weeks into the process. Eggs at temperatures around 31-32 degrees will develop into males, whereas cooler temperatures will develop into females.
