June at Noon • Near Tucson, Arizona

Here in the desert, the days are hot and water is scarce. To help them stay cool, the jackrabbits resting here have long ears with blood vessels close to the skin to shed body heat. Their long legs help keep them high off the ground to stay cool. Antelope jackrabbits (right) are so well-adapted to water shortage that they never need to drink. They simply eat water-storing plants like cacti.

In a race between the two hares, the antelope jackrabbit would win. It can reach speeds of 44 miles (72 kilometers) per hour!
