The development and evolution of earth organisms is actually just a process of energy flow, and the original source of all this is the sun. The energy released by the solar nuclear fusion is released outward in the form of light and heat. Finally, the producers on the earth perform photosynthesis and to solidify the solar energy, and finally enter the entire food chain. In essence, the death and rebirth of living things are actually just the gathering and dissipation of energy. For living creatures on earth, after death, they will eventually return to dust.

Human beings have developed a smart civilization. We have our own way of expressing our emotions. When our loved ones die, we will find a suitable cemetery to let them be buried in peace. But for animals, their lives are all fighting for food and reproduction. Members of different levels in the food chain are eventually destroyed by natural enemies.

For example, the majestic Lion King is usually held by male lions. They are domineering when they are in power, but when they are driven off the throne and start wandering alone, and they are getting older and hunting has become a problem. They will eventually find it difficult to die, and they are mostly killed by hyena .

Many animals in nature are a luxury, not to mention looking for cemeteries, but just wanting to die.

Recently, scientists discovered a "shark cemetery" in the 5,000-meter abyss of Indian Ocean . What is going on? The Australian scientific research ship RV Investigator performs detection missions in the waters near the Collins Islands. The method is simple and crude, which is to use a huge trawl to move in the deep sea like fishing.

Scientists have discovered a large number of shark teeth in the waters more than 5,000 meters deep near the Collins Islands, with more than 750, including various existing sharks and some ancient shark species.

Sharks are cartilage fish. All the bones in their bodies are composed of cartilage and are not real bone tissue. When they die, their bones are difficult to become fossils like other creatures and be preserved intact.

However, shark teeth are relatively exceptional and can be preserved for a long time, which has also become one of the main ways for scientists to study ancient sharks. For example, the size of the body can be inferred by their teeth size, such as the megalodon shark , the former overlord of the ocean, the shark family. Scientists infer their huge bodies based on the huge size of these teeth.

Megalodon can grow to 14 meters long and weigh 40 tons. Unfortunately, the megalodon has become history at present.

Glenn Moore, the fish curator from the Western Australian Museum, said that finding shark teeth of a scale in a small area is very rare and even shocking.

Do animals really look for cemeteries before they die?

In fact, from a scientific perspective, this is not a problem at all. Other organisms on Earth should not be like humans, a species with a smart civilization, but in legend, elephants have graves. When they are about to die naturally, they will break away from the elephant herd and look for a secret cemetery to welcome the arrival of death.

Legend has it that in the middle of the last century, an expedition team once hunted for treasure in a dense forest in Africa. During the treasure hunt, they discovered a mysterious cave. When everyone walked in, they found a shocking scene. Ivory bones were placed in piles, and a lot of them filled the entire cave.

Later, after the search team came back, this news spread all over the world. Many people went to look for the so-called elephant cemetery, but in the end they did not find it. Some people believed that elephants were a very smart species, and they would really look for the so-called "cemetery" before they died naturally.

So does Xiangzhong really exist?

In fact, people have actually found many places where elephant corpses gather, but they are usually concentrated around the water source. Water is an essential element for organisms, especially on the African continent. When the dry season comes, everyone is looking for water sources. In a small pool, there may be crocodiles, lions, elephants or many other herbivores to drink water on the shore, and the water source may seem like hope, but for some species it is a battlefield.

Elephants are huge in size and have few natural enemies in nature. The only one that threatens them is the lion group. Therefore, it is also explained that the discovery of gathered elephant corpses around the water source is also discussed.

Of course, there are some special situations that will cause the death of elephants' groups, and then elephant corpses will also gather. As for the statement that the elephant itself is looking for a secret place to go through the last journey of life, it is impossible from a scientific point of view.

The "shark cemetery" discovered by scientists is just a fossil of shark teeth. As for how it is formed, there are too many possibilities. After all, there will be thousands of teeth of a shark.
