Imagine you’re on an African plain and the earth beneath your feet begins to shake. You look up and see the gigantic, tank-like shape of a rhinoceros thundering towards you, snorting like a bull with its huge horn lowered. What do you do? Well, don’t try running in zig-zags (that’s how to escape crocodiles) or sit down and try to make yourself small (that appeases gorillas, not rhinos). Your best bet, even if the only things you can see around are a small rock or scrawny tree, is to hide. In fact, you stand a decent chance of getting away with it, because although nature has given the rhinoceros many extraordinary gifts, good eyesight isn’t one of them.
