Why do animals die, and what animals can t

Metabolism, birth, old age, sickness and death are the laws of nature. Animals will die, just as animals will grow from childhood to adulthood. At the time of formation, each individual has already determined the general direction of its life, growth and development, maturity, aging, and death.

Dialectics holds that everything has a process of occurrence, development, and disappearance, including man, the earth, and the solar system. Nature created a brilliant flower of life, and finally brutally killed it, this is the law of the universe, and no one can change it! A great man once said that when the end of mankind comes, the whole world will celebrate the victory of dialectics!

There is life and there must be death, this is the cosmic law that no one can change, but life is gone and extinct here, but it will be reborn in another place with the right conditions to start a new evolutionary process. It can be said that the end of life, like the beginning (birth) of life, is not subject to people's subjective will. Life in the universe is in an endless, cyclical, and never-ending process.

In addition, man is not only an animal, but also a higher animal. In the process of labor and production, early human beings gradually accumulated knowledge and became more and more intelligent through continuous learning, summarizing, and correcting mistakes, which is the most fundamental difference between humans and animals.

All creatures die, and I wish my pet didn't die, but the lifespan of a dog is only 10 years

Like humans, birth, old age, sickness and death are the laws of nature.

Why did the man die?

Can't die animals:Water bears, lamp moth caterpillar,Lighthouse jellyfish, planarians, rotifers, etc.

1. Water bears

Water bears are notoriously tenacious, and when they are in a suitable environment, they become active again. Because water bears have a very strong tolerance for adverse environments, and can stop body movement, they can withstand most harsh environments.

2. Lamp moth caterpillar

Lamp moth caterpillars, like tardigrades, are animals that can withstand very harsh environments and are very capable of surviving, reaching minus 70 degrees Celsius.

Although this will cause the blood and other cellular fluids of the light moth caterpillar to freeze, the light moth caterpillar will still be able to survive.

3. Lighthouse jellyfish

Its stem cells can continue to differentiate and can never die.

4. Planarians

Dioecious, living in freshwater.

5. Rotifers

It is a miracle to go back to a state of suspended animation in an extremely harsh environment, and once the environment is good, it will come back to life.

nutricula), most likely the only creature in the world that does not die.

According to scientists, the "lighthouse jellyfish" is only 4 5 mm in diameter, but it is such a very tiny creature that has a magical ability to "rejuvenate". According to reports, normally, jellyfish will die after reproducing the next generation, but after the "lighthouse jellyfish" reach the stage of sexual maturity, they will return to the young stage and start another life process, and theoretically, this cycle process is repeated again and again and can be repeated forever.

Animals that can't die are: East African giant snails, tardigrades, tree locusts, barramundi, jellyfish.

1. East African giant snail

It looks like a normal snail and can grow up to eight inches (20 centimeters) in length. Although they may look fragile on the outside, they are actually the "eternal kings" of the snail kingdom.

2. Water bears

It's tiny, but it's much harder to handle than a larger bear. They are indestructible. They are not afraid of nuclear bombs. They can revert to a "freeze-dried" form at any time, making them unaffected by radiation, liquid nitrogen, mineral acids, and not afraid of emotional abuse.

3. Tree locusts

It is a hybrid of a giant cockroach and a cricket. Even if they are deeply frozen, their blood still flows when they wake up. Their brains and hearts are literally completely dead when frozen, and then somehow recover well when they thaw.

4. Barramundi

Barramundi are ancient species. Its pedigree can be traced directly back to the Pancontinental period. They experienced the mass extinction of the dinosaurs. This fish can tolerate occasional prolonged droughts. With just a little water, they can suddenly rejuvenate.

5. Lighthouse jellyfish

The Daune Lighthouse Jellyfish is a translucent jellyfish that is almost unrecognizable, the size of a fingernail even in an adult, but this gelatinous low-level creature has an incredible ability: they can rejuvenate! This is unique in the animal kingdom.

The only animal that has been found to be immortal so far is the lighthouse jellyfish.

Once sexually mature and mated, the lighthouse jellyfish revert to its juvenile form and begin another voyage of life. The lighthouse jellyfish belongs to the class Hydroids, and it is the only animal that can rejuvenate. Lighthouse jellyfish rejuvenation is achieved through the developmental process of cell differentiation.

Theoretically, this cycle can be repeated endlessly, which gives this animal the art of immortality. Unlike most jellyfish, which die soon after reproducing their offspring, lighthouse jellyfish will change from sexual maturity to sexual immaturity and begin to develop towards sexual maturity again. Since the undead were discovered by scientists, the lighthouse jellyfish, which is only 4 to 5 millimeters in diameter, has become the focus of research for marine biologists and geneticists.

Lighthouse jellyfish are found in tropical waters, but scientists believe they are dispersed around the world as they are discharged into port with ship ballast water. Lighthouse jellyfish are predatory creatures that can reproduce asexually from polyps, and are theoretically immortal creatures as long as unknown oaks are eaten or die of disease.

1.Brief introduction.

Some animals encounter various difficulties and challenges in the process of survival, and some will experience desperate, oppressive circumstances to the point of eventually dying. This article will discuss the causes of this phenomenon and related circumstances.

2.The reason why animals die of despair is closed.

First of all, animals also possess emotions. For example, like humans, animals can also feel loneliness, hopelessness, and depression when they encounter difficulties and are in an inescapable predicament and an unusually harsh environment for a long time. These emotions can lead to a decrease in the animal's immunity, which increases the risk of diseases and infections in its body, which can eventually lead to the animal's death.

3.Instance: Animals are being held.

Take many animals, such as zebras, which usually run freely in the vast grasslands, feeling the fresh air and sunshine. However, when subjected to human interference and being kept in a small cage, this can cause great distress to the animal, resulting in feelings of despair, loneliness and depression, which in turn can lead to its death.

4.Example: An animal loses its home.

Another example is that many species of wildlife inhabit specific ecosystems. However, due to human sabotage or climate change, among other reasons, these animals have lost their homes. In such cases, the sedan car usually faces many difficulties and challenges, including despair, disruption of food and food chains, depletion of water sources, etc., resulting in the death of the animal.

5.Solution.

There are a number of things we can do to prevent animals from dying of despair. For example, we need to protect their natural environment from destruction. strengthen the protection of wildlife and ensure the safety of their lives; It can also provide a suitable habitat and food environment for animals, and give care and companionship, so that animals can feel a sense of security and happiness in life and maintain healthy growth.

6.Conclusion.

In short, animals are also sentient beings, they face many difficulties and challenges, and in some cases die of despair. We should be aware of the importance of wildlife conservation and take appropriate measures so that they can live, work and reproduce in a normal ecological environment, and protect our planet together.

Summary. Hello dear, I'm glad to answer for you Bears and tigers are animals that don't eat dead animals, dear, you can rest assured that it's good to kiss! The reason why bears don't like dead animals is that if it's a freshly dead animal, bears will definitely eat it, and bears don't like to eat carrion.

Because there are many microorganisms in carrion, the stomach environment of bears is not able to digest and decompose. If these microorganisms enter the bear's intestines, it is easy to cause the bear's discomfort, so the bear will not eat the rotten meat, but if you play dead in front of the bear, there is no guarantee that the bear will not eat, in case you meet a very hungry bear, it will be unlucky. <>

Hello, I am glad to answer for you Tigers, bears, wolves and other animals do not eat dead animals, you can rest assured! Bears for their own stash of food. He eats.

But for animals that are not prey on their own. He does not eat the dead. It's also for their own safety.

This is a matter of racial reproduction. For example, an animal that died of the plague if it ate it. Death is possible, too.

This is probably a habit that has been slowly formed after many generations of reproduction. <>
