Why do whales die once they come ashore?

Because once a whale comes ashore, its huge body loses the buoyancy support of the seawater, and the body will be difficult to move under the heavy volume pressure and cannot return to the sea; its bones are relatively fragile compared to land animals. The internal organs will also be compressed, causing difficulty in blood circulation and breathing. In addition, the exposure and dryness on the beach further cause the body to become dehydrated. Therefore, after the whale comes ashore, it will die if it is not pushed back to the sea by humans. To use a funny saying, the whale was crushed to death by itself after landing, or it died of thirst. Overlord in the ocean

We all know that the largest animal in the ocean is the whale. It is a veritable overlord of the ocean. No other ocean or land animal can compare with it in terms of tonnage, so whales are also the Earth's overlord. The largest known animal in the world. Whales can swim freely in the ocean and have few natural enemies. However, they are not fish in the ocean, but mammals that have adapted to ocean life. Millions of years ago, they were forced to make a living and came to the ocean from land. In life, the limbs gradually evolved into swimming fins, the body shape became more suitable for swimming in the sea, and the volume became larger, but it still maintained the breathing method of mammals, with lungs in the belly, and the nostrils moved to The top of the head makes it easier to breathe when surfacing. You will die if you get stranded on the beach

Although whales are invincible in the ocean, as mammals, they become useless as soon as they get ashore, and their lives will soon be in danger. If humans don't find them in time and push them into the sea, they will be stranded on the shore and die. There have been many strandings of whales on the coastline throughout history, sometimes a few dozen, sometimes hundreds, and sometimes hundreds of whales died on the beach within a few days, which is very regrettable. . So why did the whale, which once lived on land and was the most powerful in the ocean, die as soon as it landed on land? Let us take a look at the reasons below. Most whales are crushed to death by themselves

Whales have lived in the ocean for tens of millions of years, and their bone density and body structure have changed. Their bones, thorax and abdominal cavity are not as strong as before, but in sea water Supported by strong buoyancy, whales can not only swim freely in the water, but also grow to the largest size on earth. However, once they are stranded on the shore, their body structure cannot support their weight. Their own weight will make them unable to move independently. It is even difficult for them to swing their tails, which will put pressure on their blood circulation system and internal organs. In addition, after staying on the beach for a long time, the sun exposure will dry out their bodies and lose water. Their body temperature will also rise rapidly, and they will soon die of dehydration, that is, death of thirst.
