Reproductive System

Hippopotamuses reach sexual maturity at around age eight. The have a calf about every two to three years and they have one calf at a time, and this happens from age eight until the end of their life. They give birth to live young. The gestation period is seven to eight months which many mammals can be longer, like an elephants is 22 months. Hippos are born under water and swim to the surace to take their first breath. A newborn hippo is about 50 inches long and is between 60 and 110 pounds. Their mother produces milk or her cal until they are about six to eight months old, until they are weaned.
