Giraffes are the tallest terrestrial animals, renowned for their long necks, legs, and distinctive coat patterns. They inhabit savannas, grasslands, and open woodlands in sub-Saharan Africa. Adult males can reach heights of up to 18 feet (5.5 meters), while females are slightly shorter. Giraffes primarily feed on leaves, flowers, and fruits from tall trees, especially acacias. Their long necks, which contain the same number of vertebrae as most mammals, help them reach high foliage. Social animals, giraffes form loose, fluid groups known as towers. Despite their size, they can run at speeds up to 35 mph (56 km/h) over short distances.
