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.
