A Black rhino came to the waterhole where there were already 6 white rhino in residence, this caused a momentary stand off as the big male white rhino stood its ground.
When you see the size difference you would think the white rhino would have no problem seeing off the smaller black rhino........but, the white rhino is a quite placid animal where the black rhino is a very aggressive animal, but in the end commonsense prevailed.
