This is a short movie clip of a male hippo charging a boat on the Chobe River in Botswana – note how fast this animal is moving under the water. I’ve experienced a similar scenario while drifting down a river in southern central Africa. The difference between this movie clip and my experience is that the hippo actually got hold of the boat I was in. It was an aluminium  jon boat so heavy, it required five men to move it on dry land, yet the hippo shook it around (with four grown men inside it) as if a balsa toy-boat. We only suffered minor cuts and bruises; we were very lucky. Much wiser after the hippopotamus-boat-eating incident, we always motored past groups of these animals (as this movie clip demonstrated) – a valuable tip when encountering them in a river/lake.
