Animals have natural predators, so people are also animals, so why don t they have natural predators

Human beings have been out of the range of low-level creatures, and human beings have long had no natural enemies when they use their wisdom, and the natural enemies of human beings have been conquered by human beings.

In fact, people also have natural enemies, that is, themselves, but they don't know it, and defeating themselves is the greatest victory!

According to records, 8 million years ago, human beings had a natural enemy, they were dinosaurs, which fed on australopithecus, and finally humans reproduced and evolved, and dinosaurs lost their food ** and slowly became extinct.

Honey badgers, killer whales, great white sharks, sperm whales, blue whales, humpback whales, giant catfish, sturgeon, arapaima, tiger fish, electric eels, Amazon piranhas, Australian Tasmanian devils, African lions, hippos, rhinoceros, elephants, Nile crocodiles, Siberian tigers in Asia, brown bears, jaguars in the Americas, brown bears, bay crocodiles, pythons in South America, elephant seals in Antarctica, polar bears in the Arctic have no natural predators.

The honey badger is very **, it is an omnivore, whether it is a small mammal or a poisonous snake and bee, it is its prey. It is short-tempered, very bold, and very aggressive, even if the lion provokes the honey badger, the honey badger will fight with the lion to the ends of the earth, and some lions are even forced to climb trees to avoid the honey badger.

The Tasmanian devil is the only non-extinct member of the Tasmanian devil genus, about the size of a puppy, but muscular and muscular. Characteristics include black fur, a foul smell when attacked, a piercing cry, and a demeanor when eating.

In addition to hunting, Tasmanian devils also eat carrion. They usually act alone, but sometimes also eat with other Tasmanian devils.

Killer whales are large toothed whales with a length of 8 to 10 meters, a weight of about 9 tons, a slightly rounded head, and an inconspicuous beak; dorsal fin tall and erect, curved up to 1 m; The body is black and white. The wings are far apart. The temporal fossa is large. The mandible is comparatively shorter.

There are 10 to 12 conical teeth per denture in the upper and lower jaws. With a slender mouth, sharp teeth, and a fierce temperament, it is a carnivore, good at attacking prey, and is a natural enemy of penguins, dolphins, seals, and other animals. Sometimes they also attack other cetaceans, even great white sharks, which can be called the overlords of the sea.

The natural enemies of humans are flies, mosquitoes, rats, cockroaches, snakes, and other animals.

1. Flies. Flies can carry up to 60 species of bacteria and pose a huge threat to the human body. Numerous tests have shown that large amounts of hair on the surface of flies, as well as digestive and blood systems, can carry pathogens and then transmit them to humans through contact with food.

When flies eat, they first spit out the bursal fluid, dissolve the food before inhaling, and while eating, spitting, and pulling, people are prone to disease after eating these contaminated food and utensils.

2. Mosquitoes. Mosquitoes can spread diseases, because mosquitoes like to live in a dark and damp environment, the body contains a large number of bacteria, viruses, when sucking blood on the surface of the human body, these bacteria and viruses will enter the human body through mosquitoes. After the mosquito sucks blood, it will also produce red bumps on the **, which makes the ** itchy and unbearable.

It can also hinder people's rest, interfere with normal life, and affect the quality of sleep.

3. Rats. Rats move around in a variety of places every day and carry a variety of bacteria on their bodies. Without knowing it, humans eat the food that rats have eaten, and at this time, the virus transmitted by rats in the food will enter people's bodies, and people may suffer from epidemic hemorrhagic fever, which is likely to endanger life if it is not timely.

Moreover, in order to grind their teeth, rats often gnaw on doors, closets, etc. In the fields, rats often steal food, dig fields, and destroy trees, which is harmful to the development of forestry and agriculture. In addition, rats burrowing everywhere also endanger the quality of the building, bringing hidden dangers to people's lives.

4. Cockroaches. Cockroaches are one of the more common pests because cockroaches are animals that eat and pull, and things and objects that they crawl on can be contaminated. Cockroaches themselves are not poisonous, but they carry many germs and parasites in their bodies, and accidentally bitten by cockroaches may be infected with the contagious plague of the murine bacillus and the paradysentery bacillus that cause diarrhea.

Cockroaches have the habit of biting casually, and if they accidentally bite on items, etc., it will lead to damage to items, damage and malfunction of communication equipment and facilities.

5. Snakes. There are 2,500 species of snakes in the world, including more than 650 species of venomous snakes, threatening a vast area of one billion people. According to the World Health Organization, five million people worldwide are bitten by snakes every year, and 100,000 of them die.

"Four evils".

The "four pests" refer to flies, mosquitoes, rats, and cockroaches. They all have one thing in common: they are extremely numerous. These four animals can never be counted by humans, and their distribution is almost worldwide.

Among them, mosquitoes are directly sucking human blood to transmit the bacteria and viruses they carry to humans, because of their large number, mosquitoes have become the world's most killing creatures, according to incomplete statistics, the number of people who die from mosquito-borne diseases exceeds 70,000 every year.

The only animal that does not have natural predators is the red-crowned crane. The skeleton of the red-crowned crane is strong on the outside and hollow on the inside, and the strength is 7 times that of the human skeleton, and when it migrates, it is often arranged in an ingenious wedge, so that the individuals behind can use the air flow generated when the wings of the individuals in front of them in turn, so as to carry out fast, labor-saving and long-lasting flight, the speed can reach about 40 kilometers per hour, the flight altitude can exceed 5400 meters, and it can sing while flying.

The living habits of red-crowned cranesThey often move in pairs or in small groups and groups. During the migratory season and winter, large groups of several or dozens of families are often formed. Sometimes the cluster is as many as 40, 50, or even more than 100.

However, they still disperse into small groups or family groups in a certain area. At night, they tend to inhabit the shallows or reed ponds surrounded by water, and they still live in family groups with each other, and they are very close to each other when the weather is particularly cold.

Foraging grounds and nocturnal habitats are generally relatively fixed, and usually after the daylight, various family groups fly to the foraging grounds one after another to feed, and still maintain a certain distance from each other. The high-pitched, loud chirping of the red-crowned crane is related to its special articulatory organs. Its neck is long, and its singing tube is also long, about 1 meter long, five or six times the length of the human trachea, and the end is rolled into a ring, coiled between the sternum, just like the brass instrument in Western music, it can cause strong resonance when pronounced, and the sound can be transmitted to 3 5 kilometers away.

Animals that have no natural predators are: Amazon pythons, killer whales, African elephants, tigers, jaguars, African lions, brown bears, polar bears, etc. Here are three kinds of animals that have no natural predators

1. Amazon Monty Python:

It is the largest, most powerful and powerful snake in the world. Fully grown people can reach a body length of up to 6 meters and weigh up to 150 kilograms. In terms of appearance, there is no rival in the New World.

The Amazon python has been known as a silent killer in the rivers and forests of South America since ancient times, and it has monopolized the Amazon as the top predator;

2. Killer whale: It is a large toothed whale with a length of 8 to 10 meters, a weight of about 9 tons, a slightly round head, and an inconspicuous beak. It has a slender mouth, sharp teeth, a fierce temperament, a carnivore, good at attacking prey, and is a natural enemy of penguins, seals and other animals.

Sometimes they also attack other cetaceans, even great white sharks, which can be called the overlords of the sea;

3. African elephants:

Adult African males are taller than the metre and can reach the highest metre. They weigh about 4 to 5 tons, with the heaviest recorded at 10 tons, and their tusks have been recorded with the highest kilograms. The African elephant is the largest mammal on land. Pickpocketing.

Killer whales are a huge cetacean, adult killer whales can be up to 8 meters long, their temperament is very fierce, is the natural enemy of many animals such as penguins, dolphins, seals, etc., sometimes even great white sharks have to avoid them when they encounter them, can be called the king of the sea, to be exact, they have no natural enemies except humans.

Killer whales are highly social animals, and there are some groups of families that are the most stable in the animal kingdom. Some of the killer whales' complex social behaviors, hunting techniques, and vocal communication are considered evidence that killer whales have their own culture.

It is found in almost all ocean areas, from the old equatorial source to the polar waters. There is no limit to the range of water temperature or depth. The distribution extends to many closed or semi-enclosed seas, such as the Mediterranean, the Sea of Okhotsk, the Gulf of California, the Gulf of Mexico, the Red Sea, and the Persian Gulf.
