Our country discovers whale falls first, why does observation whale fall is the sense great?

Whale falls, the fall from the sky of gigantic animal.

A whale dies, huge body is in ocean slowly sank. Body sedimentations the place that keep, left what gigantic animal gives other life to pass on. In the sea floor of gigantic animal berth, hundred years hind, was born a new live thing is regnal.

On April 2, 2020, of the Chinese Academy of Sciences " explore " boat of division take an examination ofing, discover in Nanhai a 3 meters long whale falls first. The natural whale that at present the whole world discovers falls gross is not worth 50. This our country cetacean framework of new discovery is tine whale, firm fall from the sky before long, the rear still remains wreck of body having the flesh. This whale falls, cover is sufficient precious, can let us watch very long period of time.

After cetacean death, some bodies can float on offing, can be rushed to to disembark by ocean wave sometimes. For instance cachalot, it has the adipose layer of fleshy, the body after death can float on offing. And the blue whale with huge body and humpback, after death slowly sank, but assemble is jumped over in the body as cankered gas more, tumid body can rise to surface afresh.

Floating cetacean body is very common, whale falls very exiguous however. Till 1977, a submarine is on the west of California coast, deepness exceeds 1000 meters sea floor to discover a grey whale body, people just begins to understand whale to fall truly.

Whale is marine in " cornerstone species " . Cornerstone, fundamental stone, that is to say whale is the cornerstone in marine biosphere, it affected a lot of species live, had more mainer than other live thing effect. If whale was eradicated, whole and marine ecosystem can be affected.

Cetacean type of build or figure is gigantic, metabolic system is slow, in other words, the mammalian metabolization efficiency that the cetacean metabolization efficiency of great stature compares sprat should be gotten high much. Will view specific data, the food gross that a La Jingxu wants can support whale of 7 small beards or 1500 penguin. But 50% what the weight of whale of 7 metabolism is faster small beards has blue whale only, and 8% what the weight of all penguin has blue whale only. Of large and cetacean amount decrease can reduce marine ecosystem to be measured to the reservation of carbolic element, no matter be surviving whole live thing, gone still sink marine cetacean body.

Whale goes deep-sea catch hunt, because of deep-sea pressure, cetacean meeting stops to digest excrete, and wait for float to just begin shit piddle to offing. The whale with loose, colourful quality of a material is the gold in ocean, wave medicinal powder underwater inside contain high grade nitrogen, phosphor, iron, offerred precious nutrient element to the plankton that grows in shallow sea. Plankton is the foundation of the food chain in marine ecology group, phytolankton undertakes photosynthesis, release an oxygen and offer grain ration to small fish shrimp, small fish shrimp is the commissariat of big fish and crustacean animal. Once plankton lacks nutrient element and when crop decreases, the balance of marine ecosystem can be broken.

Whale swims to offing to carry elevator like from sea floor, promote sank to offing in deep-sea material. And cetacean carriage distance is not just arrive from sea floor offshore vertical distance, still have surround whole deep-sea level carries distance. Whale preys in the place with abundant food, swim to food next not abundant place is excreted, they carry nourishment to the place that lacks nutrition like conveyor. For instance, the humpback forages in Alaska, breed period can swim to Hawaiian kitten, they are in Hawaiian excrete, carry nourishment there.

The sea floor of cetacean sank, the light cannot have been arrived at.

The darkness that does not have the light is marine, briny iciness, all around noiseless, it is a barren land. When the body sank of gigantic animal reachs infertile ground, brought a lifespring.

The body that descends at first, flesh and blood is adherent still go up in framework, saprophagous animal, for instance deep-sea shark, fish and crab can come first play knife and fork. (saprophagous animal how can discover gigantic animal body for a short while? This problem or a mystery) after about a few weeks time, flesh and blood is eaten clean, leave skeleton only. The first phases that whale falls ended.

Deep-sea and marine, do not have current erode, what cetacean framework is maintaining it from beginning to end is complete. Skull, vertebral, antebrachium is linked together, lie in sea floor quietly. At that time, it is the 2nd phase that whale falls, take cartilage and skeletal animal, for instance conch and vermian assemble collect are on framework, eat off the organic material on bone. Time went a few months or it is a few years, the 2nd phases that whale falls ended.

Next the bacterium came, bacterium of oxygen of be disgusted with uses the sulfate in seawater to digest the grease in cetacean bone. Sulfur bacterium uses the sulfide a future life of eduction of bacterium of oxygen of be disgusted with to produce energy. The 3rd phase that whale falls, last a few years. When does the 3rd phases end? Return nobody to know, because arrive till now, the longest whale falls research also lasted 40 years only.

Cetacean body brings a flourishing life group to barren deep-sea world. After gigantic animal is dead, feed back ocean continuously, promoted corporeal loop.

The place that deep-sea life flourishs, one place is the crater that has heat source, another place is whale falls brought food square. Come tens of thousands of years, whale falls brought up the invertebrate that lives in one place habitat, the evolution that transfers another place habitat is migratory.

Fall from the sky of a gigantic animal, a kingdom is arisen.
