Is not she gigantic? From its height of 18 feet, the giraffe dominates the Savannah and holds the title of "highest land mammal". Easily recognizable by its very long neck, the giraffe is tawny with large orange spots and has at the top of its head 2 small horns. This herbivore craves leaves (especially acacia) that it can graze at the top of trees. She can eat more than 100 pounds of leaves a day! It also has a very long tongue that can measure more than 20 inches. Did you know that the giraffe could run up to 31 m / h.
