FROM THE PUBLISHER
With rows of teeth, thick, armor-like skin, and distinctive long snouts, crocodiles are easily recognizable. One of the oldest animals on Earth, these large reptiles lived millions of years ago in the time of the dinosaurs. Although their only real predators are humans, many species of crocodiles are endangered because their habitats -- tropical waterways -- are steadily being eliminated.
