When a whale goes ashore, it means that a big whale dies, and after the whale dies, it takes a long time for its body to slowly sink from the sea surface to the bottom of the sea. Due to the huge size of the whale and the buoyancy of the sea, the whale carcass sinks very slowly. In the process of whale sinking to the bottom of the sea, its slow sinking speed provides a lot of food for different levels of marine life. Before it completely sinks to the bottom of the sea, 90% of whale carcasses will be decomposed. When the whale's carcass completely sinks to the bottom of the sea, its remaining carcasses and bones will become the habitat of some invertebrates, especially polychaetes and crustaceans, which will be eaten together with the remaining carcasses as nutrients. According to scientific investigation, oceanographers found that at least 43 species 12490 in the ocean depend on whales to land, and in the process of whale landing, some new species will be produced, which provides it for many creatures. Moreover, when the whale's body completely sinks to the bottom of the sea, the appearance of whale falling will bring small-scale environmental changes to the dark submarine plain. Its arrival not only provides shelter for benthic organisms, but also provides them with the source of organic matter. When the organic matter in the whale carcass is exhausted, the mineral remains of its remaining whale bones will become reefs and finally become a gathering place for some benthic organisms. Moreover, after the whale dies, its corpse can nourish other animals for fifteen years. The formation of whale landing promotes the transport of organic matter from the upper ocean to the lower ocean, because it is not enough for the deep-sea organic matter to be supplied only by chemoautotrophic bacteria. The formation of whale landing not only promotes the downward transport of nutrients, but also brings more capabilities to chemoautotrophic bacteria. Whales are the largest mammals in the world. It consumes a lot of food in the ocean all its life. It had a great demand for the ocean before its death and even returned to the ocean after its death. When the whale falls, everything is born? Therefore, the whale landing can be said to be the last tenderness left by this big guy to the sea.
