Definition
Reptilia is a class of vertebrates that includes turtles, crocodiles, snakes, lizards, and tuataras. Reptiles are characterized by their scales or plates. They are typically cold-blooded (ectothermic). Most reptiles lay eggs (oviparous), though some give birth to live young. Reptiles have adapted to a wide range of environments. Think of them as the scaled survivors of the animal kingdom. π
