These cold-blooded animals possess a suite of distinct biological and physical features that distinguish them from amphibians, birds, and mammals. This evolutionary leap freed reptiles from the necessity of returning to water to breed, a constraint that bound their amphibious ancestors.

Additionally, they have a three-chambered heart (with some exceptions like crocodiles, which have four chambers), a feature that plays a key role in their circulatory efficiency. Many species, particularly snakes, utilize forked tongues to collect chemical particles from the air.
The Defining Physical Traits The most immediate answer to what are characteristics of reptiles often centers on their skin. They then insert these tongues into the Jacobson's organ, located in the roof of the mouth, to analyze the scent trails of prey or predators.

This class is typically divided into four main orders: Testudines (turtles and tortoises), Squamata (lizards and snakes), Crocodilia (crocodiles and alligators), and Rhynchocephalia (tuatara). Reptiles possess a more erect posture than their amphibian ancestors, with limbs positioned directly underneath their bodies.
