Luo Tuo eats cacti why he is not afraid of being pricked
Camels have thick, hard leather lips, protected by hair that allows them to nibble on hard, sharp plants from being stabbed. In fact, not only camels, many herbivores have similar structures, such as horses, cattle and other animals have thick lips, while carnivores have almost no such lips; Because they need to show their teeth to kill prey and eat. In addition to the thick lips characteristic of herbivores, camels also have a "unique skill", that is, the structure of the inner wall of the mouth. The lips only protect the camel from getting hurt while nibbling on the cactus, and the subsequent chewing process requires more protection. The inner wall of the camel's mouth has many hard fleshy spines, and its hard structure is stronger than the thorns of the cactus, and the thorns of the cactus can be crushed in chewing. In addition, the camel also has a very thick tongue, which makes it eat cactus like eating a "cake" with a relatively hard shell, and it will not be hurt.
