Where do Reptiles Live?

Most reptiles are terrestrial, meaning they live on land. However, a few reptile species are aquatic, living in water environments. Some reptiles species that live underwater include saltwater crocodiles, male and female green sea turtles, the marine iguana, and sea snakes.

Reptile Facts for Kids – Body Temperature and Other Fun Facts

Reptiles are ectothermic, meaning that they get their body heat from their environment. They do not have a constant body temperature, instead, it changes based on the environment they are living in. This makes reptiles very adaptable to different climates including both warm and cool places.

Reptiles have a slightly different arrangement of the heart than mammals. Reptiles have a three-chambered heart, unlike the four-chambered heart of mammals. This allows reptiles to remain active even when their body temperature drops significantly.

What do Reptiles Look Like?

Reptiles have scaly skin that helps protect them from predators and the elements. The scales can be different colors and sizes, depending on the species.

All reptiles are vertebrates, meaning they have a backbone. For some reptiles, you can actually see these thin bony plates. Other reptiles, such as the turtle, have a hard, protective shell. This shell provides turtles protection and in some turtle species, their shells also serve as a defense mechanism against predators.

Reptile Facts for Kids – Characteristics of Reptiles

Reptiles are oviparous, meaning they lay eggs. The climate and environment a reptile is living in determine when the eggs will be laid. Some species lay their eggs in holes dug in the ground to protect their young from predators. The eggs can be either hard or softshell and the incubate period (the time between when the egg is laid and the animal is hatched) varies depending on the species. Have you ever seen a reptile lay eggs? Or a reptile hatching from an egg? Both can be incredible sights to see!

Reptiles have a good sense of smell and sight, but their hearing is not as developed.

What do Reptiles Eat?

Reptiles are carnivores, meaning they eat meat. Their diet can include insects, other small animals, and even other reptiles.

Some reptiles have sharp teeth to help chew their food, other reptiles don’t chew their food at all! Snake species will sometimes swallow their prey whole, while crocodiles will use their sharp teeth to tear apart their prey. A single crocodile tooth can grow up to eight inches long!

More Fun Reptile Facts for Kids

What is your favorite kind of reptile? Maybe you like the crocodile for its incredible teeth and powerful bite. Or perhaps you like the lizards for their scaly skin and ability to camouflage. Or are you a fan of the snakes? I know I’m not, but some people appreciate their slimy appearance and the fact that they eat mice. If you are like me, though, you probably like the turtle for its beautiful shell and unique personality.

No matter which reptile is your favorite, or if you even like reptiles at all, you can’t deny that these are pretty cool creatures. Many reptiles have different characteristics and appearances but they all share a lot in common. Lizards and turtles both have dry, scaly skin and the ability to camouflage but turtles have a hard, protective shell that lizards do not. And crocodiles have some of the largest teeth of all creatures out there and snakes, on the other hand, have rather small teeth.

Each reptile is unique and each reptile has so much more you can learn about them, so keep reading, researching, and if you can, get out there and go exploring! You never know what animals you may find. Just make sure to keep your eyes open, so you don’t miss any reptiles hiding among the trees.
