THE WORLD TALLEST MAMMAL

Giraffes are the world's tallest mammals, thanks to their towering legs and long necks. A giraffe's legs alone are taller than many humans—about 6 feet (1.8 meters). These long legs allow giraffes to run as fast as 35 miles (56 kilometers) an hour over short distances and cruise comfortably at 10 miles (16 kilometers) an hour over longer distances.

Typically, these fascinating animals roam the open grasslands in small groups of about half a dozen.

                                                                                                       Bulls sometimes battle one another by butting their long necks and heads. Such contests aren't usually dangerous and end when one animal submits and walks away.

 Even the giraffe's tongue is long! The 21-inch (53-centimeter) tongue helps them pluck tasty morsels from branches.
