The tallest animal in the world is the giraffe. Known for its long neck and legs, the giraffe can reach heights of up to 18 feet (about 5.5 meters). Native to Africa, these towering mammals primarily feed on leaves from tall trees. Giraffes have a unique gait that allows them to move gracefully despite their height. Their long necks have evolved not only for reaching foliage but also for male combat, known as "necking," where they swing their necks to fight for mates. Their striking appearance makes them a favorite among wildlife enthusiasts.
