If you encounter a herd of African bush elephants roaming the savanna take heed: The one in charge is likely the family’s matriarch. And it is best to get out of her 7-foot, 3-ton way. Herds, or family units, are made up of the matriarch and related females. When calves are born, they’re raised in a cooperative manner by the mother with the help of other young female elephants called allomothers.
The African bush elephant has the largest body and biggest brain of any land mammal. Scientists think the elephant’s complex brain structure is a good indicator of its intelligence—not just because of the brain’s size, but the fact that elephants in both the wild and captivity have exhibited complex and emotional behaviors, all signs of a highly intelligent species.
