The Defining Physical Traits The most immediate answer to what are characteristics of reptiles often centers on their skin. This class is typically divided into four main orders: Testudines (turtles and tortoises), Squamata (lizards and snakes), Crocodilia (crocodiles and alligators), and Rhynchocephalia (tuatara).

Reproduction is another key area where reptilian traits shine. This anatomical shift allows for greater weight support and more efficient locomotion on land.
Each order showcases variations on the core reptilian theme, from the shells of turtles to the venomous fangs of certain snakes. 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.

Their evolutionary journey from water to land is etched into their very physiology, making them masters of terrestrial existence. 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.
