On the west coast of Tasmania, Australia, 230 heads pilot whale stranded on the beach.
They swayed their tails and pectoral fins slightly, trying to break free from the shackles of the beach. , but their fins cannot support their overweight weight, and after stranding, they can only wait for death on the beach . Such a scene is really heartbreaking!
Australia's handling of the environment and climate has always made everyone complain. Inadequate management, lax control, etc. are all important reasons why everyone criticizes the country. The tragedy of 230 pilot whales stranded together makes everyone more question how Australia protects nature and these precious animals.
It is reported that when the more than 200 pilot whales of were first discovered, more than half of them had died in . This is mainly because the body of whale is about 7 meters long and weighs more than 7,000 kilograms. Once it leaves the buoyancy of the sea water, its bones and internal organs will soon be unable to support the weight of the body, and the epidermis will also be quickly dehydrated.
Logically speaking, whales usually live in the deep sea. It is already a great joy to see one or two heads in the shallow sea on weekdays. However, this time, more than 230 heads were stranded at once. The scene was spectacular and it was also a pity. At the same time, caused a lot of speculation.
Why is the pilot whale called pilot
pilot whale also known as giant whale , it is considered to be an high IQ animal.
Fishing boats come and go in the ocean, and they will leave food like small fish and shrimps. The smart giant whale found that had meat to eat with the fishing boat, so they flocked to and accompanied the fishing boat , swimming upstream and downstream, looking like they were piloting.
At the same time, due to the huge size of the pilot whales, they will avoid the reefs hidden under the sea when swimming, and , so it will be more secure for ships to follow them.
Of course, there is another reason. The courage of the pilot whales is completely in proportion to their size. They are so pitifully small that they can scare them to turn around and run wildly. Therefore, on weekdays, likes to live in groups in , and usually has a "leading whale" in front of them, leading the entire ethnic group to carry out daily activities.
The tragic fate of the pilot whale
The stranded incident of the pilot whale is not the first. As early as a year ago, there were 70 pilot whale stranded in the same place. At that time, the rescue operation of Australian personnel lasted for nearly ten days, but this only saved more than 100 people. Moreover, even if they were rescued, they might not live long after returning to the sea.
After all, I stayed on the shore for so long, and the water in my body has been almost lost. The pressure on the internal organs of weight has always existed. is equivalent to a seriously ill person. Although he is still alive and may have a good mental state, the damage to the internal organs of is irreversible , which is something we cannot control.
However, in addition to this kind of death caused by the whales themselves, there are actually some whales in the world whose fate is quite tragic. They are surrounded by people in the sea and then killed slowly, which is enough to be considered a huge torture for this living species.
Denmark has an area called Faro Islands . is not only not illegal to hunt whales here, but it is even an custom . Every summer, people there will organize and plan to hunt whales. During that time, the waters near them will be dyed bright red by the whales' flesh and blood, and the scene is very terrifying.
This approach is undoubtedly wrong. They hunt whales not because they sell large quantities of whales, nor to eat whales' meat. After all, their meat is not delicious, and is dry, hard and very tidy.
So the Danes did this just for the so-called "traditional" , using this excuse to trample on the life of whales and satisfy some of their excessive desires. However, doing so will cause countless whales to lose their lives, and will also cause indelible irreversible harm to the marine environment and even nature.
Specific reasons for the stranding of high IQ pilot whale
Chinese Academy of Sciences researchers showed that the causes of stranding of pilot whale may be as follows: marine noise interference, includes natural activities and human activities interfering with the echolocation system of whales, causing sonar to fail; it may also be that the whale perceived Earth magnetic field abnormal , and thus lost its direction, but this has not been fully proven, so the real reason has not yet been concluded.
After the whale is stranded, it is not only difficult to rescue, but also possible to produce a whale explosion.
Whale has a huge size, so it has a lot of appetite. Generally, they open their mouths and eat whatever they encounter. But their digestive system is generally functional. The eaten marine organism will gradually corrode in their stomachs, producing various gases. Common ones include methane and ammonia , which are combustible and pungent.
If a whale has passed away, the various protein in its body begins to decompose under the action of bacteria, and all the gases accumulate in the body. In this case, if it is airtight, will soon turn it into a "biological detonation system". Once it detonates, the consequences are simply unimaginable.
For example, a sperm whale explosion occurred in my country's treasure island in 2004. During the transportation process, a corpse of a 17-meter-long sperm whale with a weight of 50T was directly detonated in the downtown area due to improper operation. The smelly internal organs in the whale's body accompanied by sticky blood affected many people. Everyone was inexplicably wet with a "red rain", which must be an experience that they didn't want to recall again.
In fact, from the perspective of causal circulation in nature, if a whale can die naturally, it is a favorable thing for the circulation of natural resources, and it can even maintain the normal survival of tens of thousands of undersea biological individuals .
For example, its fat will be eaten by carnivorous fish, its debris will be eaten by scavengers, and its bones can exist for hundreds of years, becoming the "home" of various benthic organisms. This is also the saying that "-- whale falls , and all things are born " comes from this.
