I remember a sentence that Sanmao once said, which made a special impression, at the end of the Sahara Desert, my home. The endless yellow sand of the desert, without water, all of this will not only make people feel desperate, but even the creatures will be the same. The desert is inseparable from the camel because it is drought tolerant enough.
However, there is a more hardy animal, which you may never have heard of, which lives in Australia, and they never worry about drinking water, which is known as the walking cactus. The thorns are like natural armor, making it impossible for enemies who want to attack it, but these thorns are not as simple as everyone thinks.
For its miraculous drought resistance, a professor has done a specific study, and the results of the study show that these prickly skin are actually very conducive to retaining moisture. What's even more unexpected is that its skin is like a sponge, absorbing moisture from the ground at any time.
When they are thirsty, they collect the water in the body's blood vessels and then transport it to the mouth to relieve the thirst. This way of replenishing water is also special, digging a hole in the desert, sleeping and becoming alive again.
In fact, this animal originally did not have such an attribute, but in order to fight the drought of the desert, they turned themselves into drought-tolerant animals, in the face of the challenges of life, learning to adapt is the solution, after all, the survival of the fittest is really the eternal truth.
