Whales are said to sense death, and when they realize that life is coming to an end, they leave the group and wait alone for the last moment to come. The same is true of the most loyal dogs around humans, sensing that life is about to end and leaving alone, quietly choosing a place to wait for the moment to come
A whale falls and everything lives
Just six words, but a shocking depiction of the whale's life. This is the greatest curtain on earth, and it is also another rebirth of them. Whale fall actually refers to the phenomenon of whales sinking to the bottom of the sea after death, forming a deep-sea ecosystem. According to research by scientists, it has appeared 30 million years ago, but the process is very long. It usually needs to be done in four stages
Mobile scavenger
During the sinking process after the whale dies, a large amount of organic matter and opal in the body tissue will directly attract sharks, hagfish and other organisms to nibble on. Whales are so large that they can be enjoyed for up to two years, during which time more than 90% of the carcasses are decomposed
opportunism
The whale carcasses crashed to the bottom of the sea two years after being eaten, and at this moment the hairy and crustacean sea creatures smelled and besieged on all sides. They are able to use whale bones to make a home for themselves in a very short period of time, and they can reproduce by ingesting food
Chemical energy self-nourishment
At this time, in addition to a pile of white bones, the rest of the whale carcass has been exhausted, a large number of anaerobic bacteria began to move and enter the whale bone to decompose lipids, combined with the dissolved sulfate in the seawater to produce hydrogen sulfide, chemical energy to nourish bacteria [such as sulfide bacteria, etc.], and can also oxidize these hydrogen sulfide with oxygen in seawater, and then obtain an energy source
Reef stage
This stage is the last shred of evidence left in the world after the whale dies, when all the organic matter of the body is exhausted, the remains left behind will eventually become the habitat of the seabed creatures in the form of reef rocks
According to scientists, it takes whales nearly a hundred years from death to complete decomposition
During this century, whales have maintained the survival of at least 12,490 organisms in 43 species. This not only changes deep-sea ecosystems, but also directly affects the evolution of new species. Due to the lack of sunlight in the deep sea, organic matter is very scarce and there is almost no energy source, making it extremely difficult for organisms to survive here. And whale drops make up for this gap, transporting the upper layer of organic matter downwards in the process
Whale burst
In addition to the normal whale fall, there are also whales that die because of accidental stranding, and their ending is very unfortunate. Because he did a little more in the ocean before he died, with the exposure of the sun and the growth of microorganisms, the undigested fish and shrimp in the stomach began to rot, producing a large amount of methane, hydrogen sulfide and other gases, increasing the pressure on the abdomen and intestines. Explosions caused by improper disposal
Genocide is gradually becoming extinct
In recent years, whales have run aground more and more, basically due to human activities sonar interference, boat scratches and collisions. An adult blue whale can reach up to 30 meters in length, equivalent to the length of a Boeing 737. Breathing on its surface, the sprayed column of water can reach up to 12 meters. As the world's largest mammal, the entire race is gradually going extinct, and the biggest murderer is Japan
In 2009, a documentary called Dolphin Bay was released, causing outrage around the world. The bloody scenes of Japan's dolphin hunting are recorded, and the red-stained bay is heartbreaking to see.
Japan's commercial whaling dates back more than 400 years, claiming to be the world's largest whaling and whale-eating country, and they have never ignored the opposition of the international community and animal protection organizations. Every year in the name of scientific expeditions to hunt whales, dolphins and other marine life, there are relevant data show that Japan at its peak of the number of whaling reached more than 75% of the world, this figure is simply outrageous
Once whales become extinct, the marine ecological chain and its human ecosystem pose a serious threat and can even accelerate global warming
Natural disasters have occurred frequently in recent years, and we human beings should reflect on what the reasons for this are
