On the beach of the Shenzhen Beach in Guangdong Province, a 3-meter-long sperm whale ran aground, and after the surrounding citizens found it, they immediately organized a rescue.
Compared with the sperm whale that ran aground in Ningbo waters last time, this time the sperm whale is smaller, the weight is significantly lighter, and the rescue is less difficult, and the citizens relay it back to the sea.
Unfortunately, the sperm whale was sent back to the deep sea, washed up on the beach, stranded again, and eventually died.
According to Mr. Yang, a rescue worker at the scene, the sperm whale would swim at first, but it was injured and bleeding a lot. At present, the carcass of this sperm whale has been taken away by the relevant departments for investigation.
Why are stranded frequently?
Many people may still remember the 19-meter sperm whale stranded in Ningbo, when the stranded sperm whale was larger, heavier in weight, and more difficult to rescue, and had to wait until the tide to send it into the deep sea with the help of the power of the sea.
But then, floating on the surface of the sea, the remains of a sperm whale, about the size and size of the sperm whale rescued at that time, many people suspect that the dead whale is the same as the previous stranding.
Nowadays, another sperm whale stranded to death, which makes people wonder why sperm whales are frequently stranded, and what happened?
The first thing to say is that sperm whale strandings are not necessarily all external factors, but also have their own factors.
For example, aged or injured, as well as sperm whales with diseases, are most likely to be stranded, in this case, even if humans rescue them and release them back to the sea, they will be stranded twice, for example: the sperm whales that died of stranding this time were actually injured and died in the second stranding.
External factors can also lead to sperm whale stranding, such as: marine water pollution, chemical pollution, high-intensity acoustic environmental pollution, but also lead to whales foraging direction, mistakenly into the shoal.
Stranded whale rescue is very difficult, especially adult sperm whales, this is because the adult sperm whale is very large, the body length can reach more than 15 meters, the weight is about 20 tons -50 tons, once stranded, losing the support of marine buoyancy, their weight will compress the internal organs, bones, rescue is very difficult, even if the rescue is successful, it will also die twice.
Therefore, the current criterion for judging the death of stranded whales is that they are successful if they are not stranded twice, or die, more than ten days after they are released into the ocean.
At present, the sperm whales stranded in Ningbo, as well as the sperm whales stranded in Shenzhen, the reason for the stranding is not yet known, only by finding the reason, we can understand whether their stranding is their own factors or external environmental factors.
Will there be a whale burst?
Every time a whale runs aground, the most worrying thing is the whale burst.
Whale bursts are very scary, especially sperm whales stranded to die, and whale bursts are more likely to occur. This is because sperm whales will go to the deep sea to feed, in order to resist the pressure of deep sea, their skin and tissues can withstand a lot of air pressure; whales belong to mammals, belong to thermostatic organisms, they have a thick layer of fat on their bodies for warmth; and sperm whales are very large, once a whale explosion occurs, the power can not be underestimated.
When the whale dies, the fat layer keeps the whale's internal temperature from draining quickly. At the right temperature, microorganisms multiply rapidly, and a large amount of gas is produced during the activity of microorganisms.
Because the whale's skin can withstand a lot of air pressure, which also makes it difficult for the gas inside to escape to the outside of the body, so it is stored in the body, which will make the whale look like a huge balloon, and the inside of the balloon is full of rotten internal organs, fat and body tissue.
Once the internal air pressure is too strong and the skin cannot withstand it, an explosion occurs, which is the infamous "whale explosion".
When a whale erupts, the highly corrupt body tissue inside will be sprayed outside, and the large pieces of body tissue that are splashed out will directly hit people and objects; it is also accompanied by a foul odor, which can become a nightmare for many people.
There was a whale explosion in the downtown area of Taiwan Province in the mainland, which caused the local streets to smell for months, and many people remember it vividly, becoming a nightmare for a lifetime.
So will the stranded sperm whale form a whale burst?
Not really!
First of all, because this stranded sperm whale was found to be very timely, and it was taken away by the relevant departments shortly after death, and the relevant departments can artificially separate the whale skin and help exhaust when the air pressure in the whale's body is not so high.
Secondly, the size of this whale is not large, only 3 meters long, even if there is a whale explosion, it is not very powerful.
Priceless "ambergris"
There is a valuable material in high-grade perfumes, called ambergris, which is of very high value. In 2021, Yemeni fishermen found 127 kilograms of ambergris in a dead sperm whale and subsequently sold it for $1.5 million, about 10 million yuan.
So is there ambergris in this sperm whale?
This actually depends on the birth conditions of ambergris.
The formation of ambergris is related to the food of sperm whales. Sperm whales will go to the deep sea to feed for cephalopods, such as: king squid, king squid, etc., cephalopods are easier to digest, but their beaks and hard substances will be difficult to digest.
In the case of terrestrial mammals, these indigestible substances can be excreted through feces, but the feces of sperm whales are flying flocculent, and it is difficult to excrete hard feces, and if they cannot excrete them through vomiting, the indigestible substances will stay in the intestine.
The intestines desperately absorb water, compressing it into smaller objects, and then secrete a waxy substance in the intestine, which envelops the object and over time forms ambergris.
Under normal circumstances, after the whale dies, it will be eaten by the organism, and after the nibbling is exhausted, the ambergris will jump out of the intestine, because the ambergris density is small, so they will float on the sea surface, and the quality of the ambergris will become higher and higher under the combined action of seawater, sunlight and microorganisms.
Occasionally, they are swept to shore by the waves and discovered, which is the main source of ambergris in the human world.
Although ambergris is born in the body of sperm whales, not every sperm whale has ambergris in the body, and the study found that less than 1% of sperm whales have it, and the older they are, the more likely they are to appear, but it is difficult for sperm whales under 20 years old to form sperm whales.
This 2-time stranded sperm whale, only 3 meters long, obviously belongs to the juvenile sperm whale, and the probability of it containing ambergris in its body is very small, almost impossible.
