  • outlines the specialized aspects of the crocodile's physiology that enable it to thrive in a range of freshwater and saltwater habitats.

  • describes the crocodile's complex social behaviors relating to courtship, mating, feeding, and caring for its young.

  • gives examples of crocodiles using a sophisticated system of sounds and movements to communicate with mates, parents, and siblings.

  • follows the activities of a group of crocodiles and other animals in their community during a long dry season.

  • uses infrared camera techniques to film rare footage of nighttime feeding and other behaviors.

  • shows how the crocodile's skill as a hunter and flexible diet helps it to survive in difficult conditions.
