"A tiger’s tongue has small, sharp, thorn-like protuberances called “papillae”. Papillae are small, hard, hooked bumps that cover the entire tongue of the tiger. These papillae make the tongue so rugged and rough, if a tiger licks you a couple of times, it may scrape off your skin and lead to bleeding. It also helps tigers to tear the flesh and feathers off their prey’s body. Also, the more a tiger rolls up its tongue, the sharper is the lick."
