Greg Gage: If I asked you to think of a ferocious killer animal, you'd probably think of a lion, and for all the wonderful predatory skills that a lion has, it still only has about a 20 percent success rate at catching a meal. Now, one of the most successful hunters in the entire animal kingdom is surprising: the dragonfly. Now, dragonflies are killer flies, and when they see a smaller fly, they have about a 97 percent chance of catching it for a meal. And this is in mid-flight. But how can such a small insect be so precise? In this episode, we're going to see how the dragonfly's brain is highly specialized to be a deadly killer.
