In this episode, we ask: how do cats always land on their feet? How do butterflies create their beautiful wings? How do tiny hummingbirds fly in the rain? Does a subterranean mammal hold the secret to longevity?

A look at how dogs tell the time; the power behind a mantis shrimp's punch; the secret behind the kangaroo's hop; why honeybees die after they sting; why vultures fly in circles.
