The cactus that scares us has become a delicious food for camels because of the special structure of the camel's mouth. Water is very scarce in desert areas. Camels must make full use of all water resources to survive in desert areas.

Because the camel's lips and tongue are thick, the camel's tongue is covered with many small thorns. When they eat cactus, they roll up their tongues, crush the cactus with their own thorns and swallow it. Camels have been used to this process for a long time and have no feelings for them.

Camels have thick lips and tongues, which can effectively prevent them from being stabbed by cactus. Water and plants are very scarce in the desert. Cactus is a rare water storage food in the desert. Cactus meat is rich in nutrients and trace elements, which is much higher than other crops. Therefore, cactus grows in many arid areas of Mexico as the only source of livestock feed.

Camel is an animal that lives in the desert. Although it has a good water storage capacity, it must store some water during walking. Cactus has the most moisture in the desert. In order to eat cactus, camels make their tongues rough and their teeth hard, so they have the ability to chew cactus. But now, the camel's tongue is covered with many small thorns. When they eat cactus, they roll up food with their tongues, crush prickly cacti with their own thorns, and then swallow them.

In fact, cactus is not camel's favorite food, but it has no choice. In the desert, the lack of plants limits the camel's diet. In order to get food and plenty of water in the desert, cactus is the first choice, because cactus is the main plant in the desert and cactus is rich in water.
