Lesson Excerpt
Reptiles belong to a class of animals called Reptilia which consists of about 6,500 different species. There are four major groupings:
a) turtles
b) tuataras
c) lizards and snakes
d) alligators and crocodiles
Lizards are the most numerous of the reptiles. Snakes are carnivorous and excel at hunting and eating prey. Many snakes have specialized adaptations for hunting such as heat-detecting organs, poison, flicking tongues, and loose jaws that allow them to swallow large prey items. Crocodiles and alligators are among the largest living reptiles. They spend most of their time in the water, but they keep their nostrils out to provide air to their lungs.
