Because it looks a bit like a bare-butt mole, people also call it a naked mole rat. This animal living in East Africa is about 10 centimeters long, with few hairs on its pink or pale yellow body, wrinkled skin, and four thin and short legs. The two eyes, like needle noses, were almost completely degenerate; a pair of ears had become small buds that were barely visible. At the very front, there are two pairs of large front teeth. Both pairs of front teeth are completely exposed outside the mouth. They live all day in the tunnels they have dug, and in order not to suffocate, they have to reduce the metabolic rate of their bodies. Their very low metabolic rate makes it difficult to keep their body temperature constant. Therefore, naked rats are one of the few mammals that resembles a cold-blooded animal. At the same time, the lifespan of naked coastal rats is up to ten years, which is much higher than that of other similar rodents. The population of naked coaster rats resembles a bee colony, with 1 queen, 1-3 male companions and dozens or hundreds of female workers without reproductive rights.

10. Albino crocodile

Popular Science: These rare animals, you must not have seen, or even heard of

Seven precious white crocodiles in a university zoo in Brazil have mysteriously disappeared. It is believed that the white crocodile was stolen by animal smugglers.

The theft occurred at the Zoo of the Federal University of Mato Grosso. The zoo director said in an interview with the media that after the zookeeper fed the crocodile last time, he came over the next morning to find that the crocodile was missing, and there was no sign of breaking into the door at the scene.

A federal police spokesman who asked not to be named because of departmental rules said: "We believe the motivation of the people who stole these white crocodiles was to sell them abroad, or to animal smugglers inside Brazil. ”

According to zoo directors, this white crocodile is very rare, worth $97 million each. "We've never found wild white crocodiles, probably because they're difficult to survive in the wild," he said. They have no protective color, so it is not possible or difficult to avoid predator hunting. ”

The cultivation of white crocodiles is not easy. More than a decade ago, a breeder brought a pair of American crocodiles to the zoo with a male and female crocodile whose skin color was much lighter than the normal dark green counterpart and immediately let them begin inbreeding. These stolen white crocodiles were produced around 2005, the result of a decade of inbreeding.

The thieves left behind a surviving white crocodile, which belonged to the same nest as the seven stolen ones.

There are two others currently at the São Paulo Aquarium.

According to Brazil's Anti-Wildlife Smuggling Group, the average annual value of the global illegal trade in animals is as high as 10 billion to 20 billion US dollars, while Brazil accounts for about 15% of the share.
