The African elephant is the largest of the two species left in the world. They have extremely large ears and both the males and the females grow tusks. They can be more than 12 feet tall and weight about 14,000 pounds. There are some sub species out there that are smaller with a height of about 9 feet and weighing approximately 7,500 pounds.
These two elephants are closely related to the extinct mammoths that once roamed the planet. See below for the evolutionary history of this group. The African Savanna Elephant on average is 1011 feet tall at the shoulder and weighs between 4 and 6 tons at full size.
