Gestation. Giraffes are pregnant for a period between 14 and 15 months, or 453 to 464 days, one of longest gestation periods in the animal kingdom. Giraffes usually give birth to one offspring at a time, although twins are born occasionally. Because the gestation period is so long, the giraffe won't give birth to another baby for 16 months or more.
Reproduction. Giraffes reach sexual maturity in captivity at 3-4 years of age. However, in the wild, males may not breed until ages 6 or 7, due to a system of hierarchy among bulls. In contrast to the male breeding age, females must be physically larger to carry offspring.
