reptile

Definition

Reptiles are cold-blooded animals that have scales and lay eggs. They are ectotherms, which means that they rely on external sources of heat to regulate their body temperature. Reptiles have a backbone and lungs, and they are the first vertebrates to lay amniotic eggs.

Some common reptiles include snakes, lizards, turtles, and crocodiles. Snakes are legless reptiles that have a long, slender body. Lizards have four legs and a long tail. Turtles have a hard shell that protects their body. Crocodiles are large, semi-aquatic reptiles with long snouts.

Reptiles live in a variety of habitats, including forests, deserts, and oceans. They are found all over the world, except in Antarctica. Reptiles are an important part of the ecosystem, and they play a role in controlling populations of other animals.
