The Life of Mammals


Series 1 - Episode 4 Chisellers



David Attenborough examines the world of rodents, whose constantly growing incisor teeth are used to chisel through any obstacle and range from squirrels and the English harvest mouse to the large South American capybara. He looks at examples of their dental prowess, showing how agoutis in Panama break open rock-hard nutshells and the skills employed by beavers in Wyoming as they fell massive trees to build dams rivalling feats of human engineering.
