Watch Snakes & Other Reptiles

Close-up videography of the rat snake highlights its excellent vision, its sense of smell, its hunting ability, and its method of swallowing a victim whole. The legs, ear openings, and mobile eyelids of lizards are featured, and an emphasis is placed on the scaly skin that snakes and lizards have in common. Poisonous vipers' fangs and head shape are compared to the teeth and rounded heads of the harmless grass snake. Contrasts are made between chameleons, geckos, and worm lizards and limbless serpents such as pythons, boas, cobras, and vipers.
