Fastest land animal alive, hitting 70mph in about three seconds, which puts most supercars to shame.
Fun fact: Cheetahs can't roar — they chirp and purr instead, which is oddly adorable for a 70mph predator.
They mourn their dead, recognise themselves in mirrors, and yet we made them do circus tricks.
Fun fact: Their skin is up to an inch thick but sensitive enough to feel a fly landing on it.
