Head in the Clouds Giraffes are the tallest animals on land. An adult giraffe has a neck that exceeds 2 m in length. This neck enables a giraffe to access food that other animals cannot reach and detect predators from a long distance. Studies have shown that giraffes will browse trees at heights that other herbivores cannot reach. The water and nutrients gained from leaves enhance a giraffe's fitness by increasing survival and reproduction. However, a long neck comes with a cost: the heart mu...
