Do you know some dwarfism patients in the animal kingdom? Can I talk to you?

Have you ever seen a dwarf giraffe? 20 15 A giraffe with a height of only 2.8m was found in Mochison Falls National Park, Uganda. It's an adult male. You know, normal adult male giraffes are nearly five meters tall. They are the tallest mammals known on earth. At first biologists couldn't believe it, so they named it manager. The manager's neck is normal length, but his legs are very short. It seems that someone specially put a giraffe's neck on the horse. Dwarf towns are rare in wild animals, and it is not easy for dwarf giraffes to grow into adults smoothly, because their short legs make them lose the two survival skills of giraffes, that is, running fast and kicking, and the survival probability is significantly lower when attacked by predators.

Have you ever seen an elephant with dwarfism? So far, only two have been found in the world, both in Udawarawi National Park in Sri Lanka. The first one was discovered on 20 13. It is an adult male Asian elephant, with a height of only 1.5 meters, which is so short compared with another medium-sized male Asian elephant. The other dwarf elephant is an adult female elephant, but it is more mysterious. People only saw it through surveillance cameras on 20 18. These two rare dwarf statues are typical representatives of the wild animal Dwarf Town. The Borneo pygmy elephant living in Borneo, Malay Peninsula is such a species. They belong to a subspecies of Asian elephants and are thought to have been brought in from other places by humans in the18th century. Because they are relatively isolated from the world, on the one hand, they have limited resources, on the other hand, they lack predators or competitive relationships, so they no longer need huge bodies and gradually evolved into short people now.

Dwarf wild boar is a very distinguished species in the wild boar family. Why is it called shorty? Compared with a wild boar weighing hundreds of kilograms, its size is too small. How small is the dwarf boar? It is only 50 cm long, 25 cm high and weighs only about 5 kg, which is similar to a rabbit. It is the smallest pig in the world. At present, there are only about 250 Jurassic wild boar in the world, and most of them live on the grassland at an altitude of 300 meters in Assam province, India. They are extremely endangered species and are strictly protected by Indian laws. In fact, there used to be a large number of dwarf wild boar, but who made them so small and lovely, especially docile and less aggressive, and more importantly, the meat was delicious, which once made them almost extinct.
