Think you know everything there is to know about reptiles!?

Think again! Our cold blooded friends have many peculiarities about them, which make them so unique. Here are 10 amazing things you didn’t know about Aussie reptiles.

1. Australia is home to about 14% of the world’s reptilian population

That is a total of 869 reptile species! Whats more, 93% of them are unique to Australia! Species found on our continent include monitors, sea turtles, pythons and crocodiles.

2. The Australian Crocodile is the largest living reptile in the world

Also known as the Saltwater or Estuarine Crocodile, the adults’ size is an average of 3 to 5 metres in length!

3. Reptiles are ectothermic

Ectothermic animals can also be referred to as ‘cold-blooded’. This means the animal’s body temperature depends on external sources such as the sun, or warm surfaces.

4. Not all reptiles give birth the same way

Some reptiles give birth by laying eggs, while others give birth to live young.

5. Reptiles have scales

Scales provide protection for these animals from both the environment and other predators. It also means that they can hold in more water, and as such are able to live in dryer climates.

6. The first reptiles were thought to have evolved around 320 million years ago

This was during the Carboniferous period!

7. Soil temperature determines a reptile hatchlings gender

This is known as temperature-dependent sex determination, and essentially means that the temperature of developing eggs is what decides whether the offspring will be male or female.

8. Reptiles can cry

Studies have found that it’s not only humans that can cry! Reptiles and other animals are also able to cry, and this is a critical part of healthy eyesight.

9. Reptiles inhabit every continent other than Antarctica

This is due to the extreme cold temperatures experienced in Antarctica. Because reptiles are cold blooded and rely on an external heat source to survive, they are more predominantly found in warmer climates.

10. Large reptiles can live several months on only a single meal

Reptiles have low energy needs, which allows them to live in areas where food is in short supply.
