The Horned Rhinoceros on the Bridge of the Nose
As the second oldest, rhinoceros is not as well-known as the eldest brother, but it is also a well-known number one "person".
They have the top horns and are clad in armor, and they are known as the "Wild Samurai", which is not easy to look at.
"Tom tom!" Run! The rhinoceros is rushing over! "Boom!" The rhinoceros was mounted on a tree. It's dangerous! What is the rhinoceros doing? It turned out that rhinos regarded the swaying branches as enemies.
Because rhinos have very poor vision, both colorblind and short-sighted, they see only a vague outline of something. This defect causes them to be suspicious, thinking that the enemy is coming whenever the wind blows, and even attacks swaying branches and flying butterflies
Look, the rhinoceros's tail was curled up in a ball. What is it doing?
"Boom!" "Boom! Boom! "It turned out to be a rhinoceros in the poop!" In order not to stain the tail with urine and feces, rhinos will roll up their tails when they defecate. They dig a pit before defecating, and then bury the excrement with soil after pooping. Rhinos really love to be clean!
Hey! Rhinos, who love cleanliness, why are they rolling in mud pits?
Rhinos have no hair on their bodies, and they live in hot areas and often roll in mud pits. This not only cools down the body, but also forms a mud film to prevent the skin from being sunburned by the burning sun, just like the sunscreen we apply
"Ah, it hurts!" "Ah! So itchy! "The rhino dad and the rhino mom kept wagging their tails. Rhinos are not even afraid of lions, and who else dares to bully it? It turned out to be abominable mosquitoes!
Rhinos have thick skin, but they are tender and thin between the folds of the skin, and they also emit a smell that attracts blood-sucking insects. At this time, they need their old friend Egret to help! The egret jumps on the back of the rhino and eats the mosquitoes in a moment ~ There are many mutually helpful relationships in nature like rhinos and egrets. For example, clownfish and anemones, hippos and toothpick birds, crocodiles and swallow chinchillas, and so on.
Finally, let's take a look at the horns of rhinos. In the common impression, rhinos seem to have only one horn. In fact, the number of rhino horns varies depending on the breed of rhinoceros. Indian rhinos have only one horn, while white rhinos have two. Rhino horns are their weapons to protect themselves and defend their territory, but they are also one of the reasons for their endangerment.
People mistakenly believe that rhino horn is a cure, and the killing of rhinos in order to obtain rhino horns has led to a dwindling number of rhinos. In fact, rhino horn is composed of keratin, which is almost indistinguishable from the composition of human nails and has no medicinal value.
If you still have people around you who hold this misconception, quickly come to the children's natural science, let the baby give them science popularization!
