Reptiles, commonly referred to as a group of tetrapods, exhibit an ectothermic metabolism and undergo amniotic development. The classification of living reptiles consists of four orders: Testudines (turtles), Crocodilia (crocodilians), Squamata, and Rhynchocephalia. According to the latest data from May 2023, the Reptile Database lists approximately 12,000 extant reptile species. The field of herpetology encompasses the study of these traditional reptile orders, often conducted in conjunction with the examination of modern amphibians.
