Reptiles include crocodiles, snakes, lizards, turtles, tortoises, the extinct dinosaurs, etc. Apart from snakes which move on their bellies, all reptiles crawl on their four sprawling legs. In fact, the term ‘reptile’ comes from Latin meaning ‘creeping’. Same as mammals and birds, reptiles are also vertebrates and breathe with lungs but instead of having skin covered with hair or feathers, reptiles are covered with horny scales or scutes. Besides, reptiles are cold-blooded animals. They need to stay in the sun or stay out of the sun to regulate their body temperature, and hibernate during winter months to survive the cold.
