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.
There are plenty of other minute features, such as skin texture, number of toenails, and trunk characteristics that can differentiate the two types of elephants. Additionally, thereâs a size difference: African savanna elephants are about 8,000 kg (9 tons) and are between 3 and 4 meters tall (between 10 and 13 feet) at the shoulder. African forest elephants are a bit smaller than their savanna counterpart, and Asian elephants weigh 5,500 kg (about 6 tons) and, at most, are 3.5 meters tall at the shoulder (11.5 feet).
