David Attenborough narrates a documentary about the Scorpions. They have one of the oldest body designs on the planet and have seen the entire race of dinosaurs evolve and become extinct. They can withstand drowning, starvation, extreme temperatures and even lethal nuclear radiation. Despite this tough exterior, the real reason for their success stems from an array of sensory equipment that enables them to perceive the world in a way that we can only imagine. For the first time, this film journeys into the sensory world of the scorpion.
