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.
In addition, a female giraffe is a cow while a male is a bull. A calf is born weighing 100 to 150 pounds and measuring in at 6 feet tall. The average gestation period for a giraffe is 15 months or 453-464 days. In the wild, the average lifespan of a giraffe is 10-15 years. In human care, they've been known to live longer, 20-27 years on average. Giraffes give birth while standing up so a calf enters the world from quite a height. They fall 6 feet to the ground with hooves and head first.
