Snakes - S1.E11

Chris Packham delves beneath a snake's skin to discover what has made them some of the most successful predators on earth. Their simple body plan hides remarkable adaptations that enable them to rival their limbed, winged and finned counterparts.

Chris reveals the variety of ways in which snakes use their bodies not just to slither, but to climb, fly and swim. He explores how they use their senses to hunt, from heat-sensitive pits used to capture prey in the dark to tongues used to lure fish, and how venom acts not just to kill prey but also to pre-digest it.
