According to National Geographic, the average lifespan for a giraffe in the wild is 25 years. Giraffes have been known to live longer when in captivity in zoos.
While giraffes are quite large, they can run as fast as 35 miles per hour due to their long legs. This helps protect them in the wild so they live longer. The giraffe is herbivorous, can grow up to 19 feet and weigh up to 2,800 pounds. Another source of protection for the giraffe in the wild is that it travels in packs of around six when roaming the grasslands, giving it strength in numbers.
