Giraffes reach sexual maturity at 3-4 years of age, although, in the wild, males may not breed until ages 6 or 7, due to a system of hierarchy among bulls. Breeding can occur at any time of the year. Gestation is usually 13-15 months.
Adult males stand 15-18 feet (4.6-5.5 m) tall, whereas females are shorter at 13-16 feet (4-4.8 m) tall. Adult males weigh between 1,764-4,255 pounds (800-,930 kg), while females weigh only 1,213-2,601 pounds (550-1,180 kg). Giraffes live for 10-15 years in the wild, but average 25 years at zoos.
