Why don t elephants grow hair? Do elephants have hair?

The uniqueness of the elephant is first manifested in its size. It is the largest land animal in existence, growing up to 4 metres tall and weighing up to 7 tonnes, twice as much as the rhinoceros, which comes in second place. It also has a unique shape, the most striking of which is, of course, the long nose, and the huge ears.

Another feature of elephants that is less noticed is that the hair on their bodies is extremely sparse. Hair is one of the characteristics of mammals, with more than 99 land mammals having fur, with elephants being a rare exception.

Elephant hairy mammals are hairy, the difference is only the density of hair, some animals can reach tens of thousands of hairs per square centimeter, but some only have a few dozen. What we usually call elephants is just that.

Elephant. The surface of the surface is hairy, but it is sparse. If you look at **, in fact, all mammals.

Both have hair, and hair is one of the characteristics of mammals. Elephants live in the tropics.

They don't have to. So one of the reasons why elephants don't grow hair is the climate. But many mammals that live in the same place as elephants, such as zebras, giraffes.

and lions, both have hair, so why does the elephant's body hair degenerate so much.

The elephant's body temperature must be maintained at 36 degrees Celsius.

Left and right, if the body temperature is too high or too low, it can be life-threatening. Body temperature is metabolized in cells.

The total amount produced in the process is more or less fixed, but the ambient temperature is constantly changing. Living elephants live in tropical regions, where the climate is very hot, and they don't need hair to keep warm, so they rarely grow hair. The absence of hair on elephants today suggests that elephants once had long hair, but lost most of it in the process of evolution.

In the process of adapting to the environment, different living habits and forms are formed.

The same goes for animal hair, some animals are adapted to cold environments, so they grow long hair to keep warm. And elephants are very thick and mostly live in tropical areas, so thinning hair is a better way for them to dissipate heat. The body actually has hair, but the hair is very short, sparsely distributed, and not easy to see.

Elephants mostly grow in tropical regions, so their hair should not be too long to help dissipate heat from their bodies. In fact, they are hairy, but since they are short, thin, and relatively low in density, their bodies are visually hairless. In the process of adapting to the environment, animals form different living habits and forms.

The above is a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

Animals generally have hair to keep warm, but elephants don't usually live in particularly cold temperatures, so they don't need to grow hair.

Because the skin of the elephant is very thick, and the elephant's skin can withstand the cold, there is no need for long hair, plus everyone is a tropical animal.

Because elephants live in lively areas, where the temperature is very hot, they don't need to use hair to keep warm, so they rarely grow hair.

Elephants are indeed hairy.

Elephants live in the tropics, so they have little fur but sweat hair.

The basic characteristics of elephants are long trunks and tusks.

The rhinoceros is characterized by horns on its snout.

Antelope has slender limbs and long, thin horns.

Lizards are cold-blooded animals that bask in the sun and are oviparous.

Elephants have two large ears that can hear any wind and grass in the savannah, and can also be used to chase flies.

The elephant's two tusks are very sharp and the proportions of size are amazing, which is their best self-defense**.

Finally, be sure to introduce the elephant's long trunk, because of its long tube covered with elephant skin, like a trumpet. When the mother elephant is going to do the year-end cleaning at home, the elephant's trunk is the best vacuum cleaner; When the father elephant wants to water the flowers in his garden, the trunk is the best watering pipe The elephant has two large ears that can hear any wind and grass in the savannah, and can also be used to chase flies.

There are mammoths, and they're big, and they're all very hairy.

A must-have, and it's hard.
