The Reptiles is a PBS Nature documentary series narrated by Howard McGillin, showcasing the incredible diversity and spectacular abilities of the reptiles. The series consists of four episodes, each of which takes a look at different types of reptiles - alligators and crocodiles, snakes, turtles and tortoises, and lizards. The Reptiles begins with alligators and crocodiles, the ultimate predators at the margins of the water and the land. Then it takes a look at the reptiles that humans may fear most: Snakes. It continues to explore the reptiles with turtles and tortoises, ancient creatures marching slowly through the millennia. And finally the series concludes with the most extraordinarily diverse of all reptiles - lizards.
