The group trekked to the kenyan desert area of Africa, and while resting on the way, they found a small cave on the slope not far away, which at first did not attract their attention until a small head popped out of it.
They immediately stopped and watched carefully. Only to see this little head probe outward and crawl out of the room without anyone. It has two front teeth and long lower teeth, a pink skin that is bare, and has almost no hair on its body except for a few whiskers.
Some people laughed and said, isn't this ugly guy a mouse without hair? But some people immediately denied and gave a reasonable explanation: this is indeed a rat, but it is called a naked mole rat, and they live in the underground nest in the same organization as bees and termites, and it is rare to drill holes in the daytime.
Each group of naked mole rats has a queen and several male rats, and the rest are worker rats, a social structure that is unique among vertebrates. But if you look closely, they are not "completely naked", leaving about 40 hairs from beginning to end. Because the eyes are highly degenerate and lose vision, the only remaining hairs are extremely sensitive tentacles.
It is worth mentioning that they live ten times longer than other rodents! Because of their natural resistance to cancer in their bodies, their bodies never deteriorate until they die and can reproduce, keeping their appearance and brain tissue from aging. 93% of the genes of the human body are the same as those of naked mole rats, so scientists hope to completely solve the mystery of the longevity of naked mole rats, so that humans can achieve prolonged life and ensure vigorous vitality.
