Reptiles are a fascinating and diverse group of cold-blooded vertebrates known for their scaly skin and ability to lay eggs on land. They are part of the class Reptilia, which includes turtles, snakes, lizards, and crocodilians. Reptiles are primarily terrestrial, although some have adapted to aquatic environments. They breathe air through lungs and are ectothermic, relying on external heat sources to regulate their body temperature.

Reptile Classification
Reptiles are classified within the animal kingdom based on shared characteristics and evolutionary history. The primary classification divides them into four major groups: Testudines (turtles), Squamata (snakes and lizards), Crocodylia (crocodilians), and Rhynchocephalia (tuataras). This classification helps scientists understand their relationships, biology, and ecology.
