Ngonongoro bull elephant
There is a herd of elephants in the crater, and they are all very impressive to see. It is a bachelor herd, made up of old male elephants - driven away from their herds when they got old. The elephant families stay in the highland forests around the crater, and do not often venture into the crater. Males leave their herds at 12 years old or older, associating only with other bulls from then on (except when mating is an option).
