context: The giraffe carries about 400 to 460 days, which usually gives birth to one calf at the end, though the twins do occur several times. The mother gives birth while standing and her testicle breaks off when the baby falls to the ground. A calf is born about 1.8 meters long. After several hours, the mother can run though within the first two weeks the calf spends most of her time lying on the ground while under the protection of her mother. The calf does not need to be hunted by lions, leopards, hyenas or wolves. Only 25–50 percent of giraffes reach adulthood. Giraffes are estimated to live 20–25 years in the wild with 28 years being kept out of the park.
