Brian Cox and Robin Ince are joined on stage by naturalist Steve Backshall, zoologist Lucy Cooke and comedian Andy Hamilton as they battle it out to decide which creature wins the title of earth's most deadly. The panel reveal their own brave encounters with a host of venomous, toxic and just downright aggressive beasts, including the bullet ant, rated the most painful stinging insect on the planet, deadly tree frogs and snakes, sharks, scorpions and hippos. They ask whether our seemingly innate fear of snakes and spiders is justified, and whether the deadliest creature on the planet is in fact a human being.
