Get up. No, really. Get out of your chair, and go into the middle of the room. Now jump as high as you can. If you jumped over a few feet, that’s impressive, but a couple of feet is still only about 30 percent of the average adult’s height. Jerboas, on the other hand, are only about 3 inches tall, and they can jump about 6 feet high. That’s 2,400 percent of their own height. That’s the equivalent of a man jumping 144 feet in the air and landing like it’s a breeze. Tigger would be jealous.
Jerboas are tiny, non-threatening and not particularly suited for self-defense, but they confuse the heck out of predators by hopping sideways like a deranged, big-eared bouncy ball. Plus, they can survive in the heat of the desert better than we can, so we think they’re pretty tough.
