The tallest mammal in the world. Masai Giraffe of Tanzania, has irregural brown splotches, like jagged leaves against a buff or ochreous background. The Giraffe is a pure browser equipped to reach leaves 19 feet (5.7 m) from the ground. They drink every few days when water is available. Females and young live in maternal herds. Senior bulls (the darkest males with the most bumps on their heads) monopolize reproduction.
