If you’re referring to the little barbs on the cheetah’s tongue, they’re called papillae and are for the purpose of grooming, acting like a brush.
They are also good for scraping meat off the bones of their prey.
If I am not mistaken, all cats have them; at least the cheetah is not the only species to have them.
Are Cheetah tongues sharp?
A cheetahs tongue, as well as all cats tongues, are covered in barb like projections called papillae. As such they are often referred to as having “sandpaper tongues” as that is what it feels like is happening when you are being groomed by a Felid.
Why do cats have sharp tongues?
The tongue of a cat has tiny, backward-facing barbs (papillae) on it and they’re the things that create that rough sensation. They make it easier for a cat to rasp the meat from the bones of his prey. The barbs also aid in grooming as they collect dirt, debris and loose hair from the cat’s coat.
What animal has the roughest tongue?
Tiger’s tongue. You already have enough reasons to fear becoming prey to the world’s largest living felines. But did you know that these giant cats also have tongues lined with sharp barbs? Tigers use their needle-like tongue spurs to lick the fur off their prey.
Do lions have sharp tongues?
A lion’s tongue is as rough as sandpaper. It is covered in tiny spines, called papillae, which face backwards and are used to scrape meat from bones and dirt from fur. These spines make the tongue so rough that if a lion licked the back of your hand only a few times, you would be left without any skin!
