Big male Cape Buffalo (Syncerus caffer) takes a pause from feeding on aquatic plants to toss us the "You Owe Me Money" stare. These guys get big - around 2,000 pounds - and they get our vote as Africa's Most Intense animal. They are unpredictable and don't back down to anyone, including Lions and Hyenas. The bases of the horns on an adult male come very close together, forming a shield referred to as a "boss" in the center of the forehead. This guy's boss is pretty impressive.
