The classification of reptiles is based on their evolutionary relationships and shared characteristics.

There are four major groups, or orders, of living reptiles: Testudines (turtles and tortoises), Squamata (lizards and snakes), Crocodylia (alligators and crocodiles), and Rhynchocephalia (tuataras).

Each order is further divided into families, genera, and species.

The classification of reptiles is based on a variety of factors, including their skeletal structure, reproductive systems, and genetic sequences. Understanding the classification of reptiles helps researchers and scientists to better understand the diversity and evolution of these fascinating creatures
