Elephants have one of the longest gestation periods of any animal, ranging from 640 o 660 days, or 18-22 months for Asian Elephants, and 22 months for African Elephants. That is over double the amount of time humans carry babies to term. They give birth usually ~2-3 times per decade, and elephant young may nurse from their mothers for up to several years after birth. They live up to 70 years in the wild, but in captivity only 48, which is one of the longest living land mammals, beside humans.
