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.

The savanna is most popular to herbivores, which can dine on the diverse grasses found there during the wet season. There are more than 40 species of hooved mammals living in the savannas. How do they do this without reducing the plant supply?
