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.
Savannas are expansive grasslands typically found in countries near the equator. They are scattered with shrubs and peculiar looking trees that have adapted to extreme weather cycles. Droughts, wildfires and destructive grazing by elephants keep all but a few species of trees from establishing.avannas are expansive grasslands typically found in countries near the equator.
