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.
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. It has a saddle-shaped back, low-domed head, gently upward-curving tusks, and large ears. The tip of the trunk has two fingers, one upper and one lower.
