Did you know that Cheetahs can’t roar? Despite all of the David Attenborough and National Geographic nature films, this is something that until now I was blissfully unaware of. Sure, I had seen them dozens of times on television, and even from time to time in zoos, but the fact that I failed to hear a roar didn’t seem to signify to me that cheetahs can’t roar. I suppose I subconsciously put it down to the fact that just because I hadn’t heard them roar it didn’t mean that they can’t. So why can’t they?
The reason cheetahs can’t roar is because of a difference in a piece of anatomy in the throat called the hyoid bone. All cats have this hyoid bone, but only the big cats that can roar have a two piece hyoid bone. The two piece hyoid bone is what makes it possible for cats to roar. Cheetahs only have a one-piece hyoid bone. But not being able to roar doesn’t mean that they are a quite cat. On the contrary. They can perform a large range of vocalizations, and some of them can be heard from around a mile away.
