Upper incisor teeth develop into tusks in African elephants and grow throughout their lifetime. There are two subspecies of African elephantsâthe Savanna (or bush) elephant and the Forest elephant. Savanna elephants are larger than forest elephants, and their tusks curve outwards. In addition to being smaller, forest elephants are darker and their tusks are straighter and point downward. There are also differences in the size and shape of the skull and skeleton between the two subspecies.
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).
