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.
There is no seasonal breeding season for the giraffe. A Masai Giraffe can breed at the age of 4 years. About 50 to 75% of the calves die in their first few months due to predators. A single calf is born after a 14 â 15 month gestation period. The calf is 6 feet tall when born and grows rapidly.
