Reptiles are air-breathing and cold-blooded animals that have skin covered in scales. Here are some interesting and fun facts about reptiles.
Facts About Reptiles
- Most reptiles lay eggs, but a few species give birth to live babies.
- Unlike mammals, reptiles cannot regulate their own temperature. This is why they are classified as cold-blooded. They must rely on the sun to heat them up.
- There are over 8,000 species of reptiles living on the planet.
- Most reptiles have a three-chamber heart. Crocodiles and alligators are an exception- they have four-chamber hearts.
- All reptiles breath using lungs. Turtles have permeable skin which allows gas exchange, but they would not be able to survive without their lungs!
- Like mammals, reptiles have two small kidneys.
- Compared to mammals and birds, reptiles are not considered very intelligent. However, crocodiles do show a complex social structure and Komodo dragons (a venomous lizard) have been observed playing with each other.
- Reptiles live in almost any climate. They cannot survive in Antarctica as it is too cold (remember, they need heat to survive)!
- Snakes and lizards are the most abundant reptiles. They ‘smell’ using their tongues! They flick their tongues to capture scent particles and work out where to find some tasty food!
- Reptiles don’t have sweat glands.
