Son of a weather whale
Whales are famous for their huge size, and blue whales are the largest creatures that have ever lived on earth. As a huge creature, it naturally needs enough room for activities. A whale is a creature that lives in the ocean. In Zheng Chang's case, the vast ocean is big enough for whales to turn rivers into oceans. But I often see some news that whales are stranded. So why do whales whose diving activities are obviously limited go to shallow water and run aground?
An important reason why whales run aground is that the depth of sea water is not constant. Most people living in inland areas are in contact with rivers. Although the water level of the river fluctuates, it can't be compared with the water level of the sea. There is an obvious phenomenon in the sea, that is, tides. At high tide and low tide, the water level at the same position on the shore will be very different, so when we look at some pictures, we will find some boats parked on the beach. This doesn't mean to pull a boat in the sea to the beach, but a boat that has been floating on the water at low tide is equivalent to stopping at the bottom of the sea. Tide is an important reason why whales run aground.
In other words, when whales enter a bay at high tide, the water depth is enough for whales to move. However, if the water level slowly recedes and the whale fails to return to the sea with the seawater in time, the whale is likely to run aground on the shore at this time.
Another reason why whales run aground is that whales do it on purpose. In fact, this is one of the unsolved mysteries in nature and is called whale suicide. That is to say, although shallow water is not conducive to whale activities, many whales will still take the initiative to rush to the beach, stranded themselves on the beach, and even some whales will rush to the beach again after being rescued by humans and put back into the sea.
There is no convincing explanation as to why whales and dolphins commit suicide. Generally speaking, whales are disturbed by bad weather or sonar of nuclear submarines in the sea, and cannot accurately identify the direction by echo positioning, which leads to stranding. On the other hand, whales are very clever social animals. When a whale is stranded on the shore, it is likely to send out a cry for help, which may induce the whole whale group to rush to the beach one after another to try to rescue it. The end result is likely to be the extinction of the entire whale population.
Even some whales, after being rescued from the sea by humans, will charge the beach again under the call of their companions.
To sum up, there are three main reasons why whales are stranded. One is that whales are trapped because of low tide; The second is that its own echo positioning system is disturbed and can't tell the direction clearly, which leads to grounding; The third is to enter the shallow water area to rescue whales stranded by their companions.
On April 9, 2022, a giant sperm whale ran aground on Ningbo Beach, Zhejiang Province. Whales in the deep sea ran aground on the beach because they swam to the shallows at high tide and failed to return to the deep sea in time before low tide. As a result, the whale ran aground on the beach.
Everyone who lives by the sea knows that the sea is rising every day, but it is a small tide every day. The tide is not big, but it has only risen by one or two meters. However, every month on the fifteenth day of the lunar calendar, the tide rises once. Every time the tide rises, the sea will suddenly rise by tens of meters. Usually the time of high tide is divided into early tide and late tide. But there will be two high tides every day, with an interval of 12 hours. Each high tide usually lasts for more than an hour, and then it begins to ebb.
Every time the sea rises, it will bring a lot of seafood. Small fish, shrimps, crabs and many shellfish in the sea will come to the shallows to play and feed with the tide. However, when the sea ebbs, these small fish, shrimps and shellfish have no time to escape. Therefore, when the sea ebbs, these seafood will be left on the beach. This is a gift from the sea to people, and the ensuing rush to the sea came into being.
Every time the tide rises, some big guys in the deep sea will be taken to the beach. On April 19, this giant sperm whale was brought to the beach by the tide of seawater. At that time, after the sperm whale ran aground on the beach, local fire, fishery and animal protection organizations immediately launched rescue. First, they kept watering the whale to prevent it from dying of dry skin, and then they waited for the arrival of the late tide.
After 20 hours of all-out rescue, finally, the late high tide flooded the beach, and at the same time, the sperm whale was soaked in seawater. At this time, the male sperm whale was successfully sent to the deep sea for release through the traction and escort of the fishery boat.
Usually there are two high tides every month. The whale ran aground on the beach because it swam to the beach at high tide and could not return to the deep sea before low tide, so it ran aground.
During the high tide, the beach was submerged by seawater, which caused many small fish and shrimps to feed on the beach with the high tide. As the saying goes, big fish eat small fish, small fish eat shrimp, so many small fish and shrimp also attract whales. So when the tide is high, a large number of small fish and shrimps come to the seaside, and they also come to the seaside to feed. Then, at low tide, the whale failed to return to the deep sea in time, resulting in stranding.
When friends find whales stranded on the beach, they should call the police immediately, and then fishery law enforcement officers and animal protection organizations will carry out rescue. The main rescue measure is to keep watering whales, on the one hand, to cool them down, on the other hand, to keep their skin moist, and then when the sea water rises again, they can be towed to the deep sea by boat and released.
The reason why whales in the deep sea run aground on the beach is that when the tide rises, whales come to the beach for food with the tide, but they fail to return to the deep sea in time before the tide recedes, so they run aground on the beach.
Whales are smarter. Why do herds of whales run aground?
The reason why whales run aground is actually the ear, that is, the ability to receive sound. Then there are probably several reasons that affect their reception ability. First, because of the uncertainty of the coast, the echo will be misjudged; Second, the whale's positioning system is sick; Third, the whale's hearing is disturbed by underwater movement or the influence of other ships; Fourth, parasites in whale ears cause ear damage.
First of all, the first reason, because the coastal tides rise and fall, comes from whales.
The echo from the body can't reach the whale's ears very accurately, so they will misjudge and lead to insufficient accuracy; Or it was a misjudgment, which led to the failure to take countermeasures and led to the stranding of whales.
This kind of misjudgment or misjudgment has a lot to do with the third reason. On the one hand, the sounds made by some large ships may disturb marine life, on the other hand, they may also be caused by underwater explosions. Their echoes are disturbed, so it is naturally impossible to judge accurately.
Let's return to the second reason. Due to the pathological changes and degeneration of the positioning system, whales cannot accurately analyze their position. Therefore, it is very likely that you will encounter the danger of being stranded under unknown and unknown circumstances. Just like us humans, no matter how clever we are, if we find our way, we will definitely get lost. In the process of getting lost, it is inevitable to encounter danger.
The last reason is that the whale's own ear may be damaged, and the culprit is the parasite in the ear. These parasites feed on whales, and some parts of their ears must have been hurt for a long time. Therefore, hearing is naturally affected.
Whatever the reason, the whales are pitiful. Once stranded and not found in time, they are likely to lose their lives. So if it's really our human reason, please take measures to protect marine life. If it is not because of human beings, but because of themselves, then maybe there is nothing we can do.
