The African Buffalo, Affalo or Cape Buffalo (Syncerus caffer) is a large African bovid. It is up to 1.7 metres high, 3.4 metres long. Savannah type buffaloes weigh 500–900 kg, with only males, normally larger than females, reaching the upper weight range. Forest type buffaloes are only half that size. The African Buffalo is not closely related to the slightly larger Wild Asian Water Buffalo, but its ancestry remains unclear. Owing to its unpredictable nature which makes it highly dangerous to humans, it has not been domesticated, unlike its Asian counterpart, the Domestic Asian Water Buffalo.
