Why did the animal have a stag?

* Why do animals have a tail and humans do not?

* What are the benefits of tails, if they have any benefits?

I begin by answering the last paragraph of the question: Do tails have benefits?
The answer I say, and it is not specifically related to this question, is that there is nothing in creation that does not have benefits. Nothing was created in vain. Then I open my ears to this particular question and say, also self-evidently, that I cannot imagine an ox, a donkey, or a dog running among us without a tail.
It is then the door from which the curtain was lifted. Worse than this is that the one from whom the curtain was lifted was a cow, a donkey, or a dog. Food outlets and chaste touches must be hidden from the eyes of a person with a genuinely gentle temperament. And don't ask me why? This is the rule of nature in which there is no logic, and what is in need of logic, it is like many of the facts of this existence. If a person walked naked, I would wish, by God, that he had a tail. Nude girls on stage often feel the need for a tail, so they wear a tail behind them.

Added to this are meanings related to beauty. How many dogs become more beautiful by having their tail covered with hair and then arched and high as they walk with their head held high and their nose waving swagger. The same applies to the cat. And also the Persians. The most flamboyant animal has the peacock's tail.

The benefits of tails for animals are different.
Before we begin and bring proverbs, we should point out that not all animals have a tail. The tail is an extension of the vertebral column, so it is only found in vertebrate animals, whether they walk on all fours, crawl on land, swim in water, or fly with a wing.

- The tail in cats and dogs, and in cattle

The tail in many animals, such as cats and dogs, is used to balance the body when moving, whether walking, or

(*) We use this word in its linguistic sense, which is (the last thing), whether this last thing is an extension of the back chain or something else.

Jumping and jumping, or overturning. Cattle brush flies off their backs with their tails, and man imitated them in that, so he used the fluff and made it from hair.

- Sheep's tails

We do not forget the tails of sheep, as they serve as a storehouse of food, as fat accumulates in them. In some of them, an amount of it accumulates that weighs down the tail, to the point that sheep and ewes groan with it.

- Monkey tails

Then monkey tails. The tail, especially for South American monkeys, has another hand. It's a tail that works like a hand. He wraps himself around the tree branches where these monkeys live, and holds them like a hand, or more tightly.

These apes, with their front hands and hind legs, which are in fact two other hands, and their tail, which is a fifth hand, move between trees with a unique mobility that earned these apes the title of the first acrobats of the animal kingdom.

(The peacock. It is the most wandering bird with its tail.)

(Kangaroo)
(It may jump and rise a few feet, and reach a range of 25 feet. You see the previous kangaroo has prepared to land, so it carried its legs forward and prepared to descend on three: its hind legs and its tail, while its front hands are used to hold food.)

( Beaver )
(And the most amazing thing about it is its tail, when it hits the water when it is frightened, warning its people with it!!)

- The tail of the kangaroo

The famous geographer James Cook arrived on the coast of Australia in the year 1770. He was struck by a huge animal that weighed about 200 pounds and was so long that it reached ten feet with its tail, and the tail alone was 4 feet long, but it was a tail with some thick muscles. When it sits, it sits on its hind legs and relies on its tail. It is as if it is sitting on three legs. This animal jumps with strong, high jumps in the air, and its tail participates in balancing it and distributing its weight in the air.

This is the animal known as the kangaroo

- And the beaver tail

And the beaver's tail is one of the most visible things in...
His creation.

It has a tail that lengthens to 10 inches. It is wide and spreading, covered with skin, with a horny layer with many scales.

When the beaver sits, he relies on his tail, and when he descends into the water, he uses his tail as an oar and uses it as a rudder to navigate the water.

If something startles it, it hits the surface of the water with its tail high to warn the beaver community of the danger.

-And lizard tails

They are tails that perform their general function in terms of performing their share in balancing the movement of lizards. They are very fast moving and change directions very quickly, so they are in apparent need of tails.

However, they are easy tails for lizards when things go wrong. If the lizard finds itself in trouble, such as if an enemy attacks or injures it, the first thing it will get rid of is the tail, which separates from it, and after it separates, it continues to move in a fast, intense movement that draws attention to it. The lizard takes advantage of turning its gaze away from its tail and flees. Instead of the tail, a new tail grows, and it is not exactly like the first tail.

- Scorpion's tail

The scorpion, as is known, has a long tail that it bends high above its body until its tip reaches where its claws catch the victims in front of it. This tail carries at its tip a hollow stinger that the scorpion fills with poison that emerges from a sac located at the last joint of this tail. And with this needle you strike.

- And the tail in fish

The tail in swimming fish is its primary driving force in the water. It goes right, then left, then right, and pushes the fish's body forward. The fins are its direction, and the tail of the fish is part of its body. However, it has become compact and widened, and strong muscles have been developed in it to contribute to the necessary movement.

- And the tail in birds

In birds, the last vertebrae shorten and compact until they form a bone that carries all the tail feathers. Those feathers are known to be dangerous in flight. And in his guidance.
