Giraffe Eating Leaves

Giraffes are the world's tallest mammals. A giraffe's legs alone are taller than many humans—about 6 feet. These long legs allow giraffes to run as fast as 35 miles an hour over short distances and cruise comfortably at 10 miles an hour over longer distances.
Giraffes use their height to good advantage and browse on leaves and buds in treetops that few other animals can reach.
