Chinese white dolphin, a national treasure at sea, belongs to the family of cetaceans, so it is also a mammal that evolves and lives in the sea. Like humans, their body temperature is constant, and they are pregnant and reproduce like humans, feeding young dolphins with milk and breathing with their lungs. Their appearance is very beautiful, the whole is streamlined spindle-shaped, and the color is mostly white or pink-gray, which is very pleasing. Has been called by coastal fishermen since ancient times? Sea pig? Or? Mazu fish? Visible people's love. The number of Chinese white dolphins is also very rare, which can be compared with that of giant pandas, so they are also called national treasures or giant pandas at sea. 1997 When Hongkong returned to China, the Chinese white dolphin became the mascot of the return.
Lovely pink dolphins are mostly gray or black. Dolphins with such bright pink eyes are very rare, and we Chinese white dolphins are generally white and pink in adulthood, which is naturally loved by people. However, it is not the white dolphin's skin that is pink, but the color of the blood flowing from the capillaries under the white dolphin's skin, which makes it look white and red, adding a lot to the face value. From birth to about one year old, the skin of white dolphins is gray-black. When they grow up to one to three years old, their skin will turn light gray, and their body color will gradually fade as they continue to grow, and many spots will grow on their bodies. But when they grow into adults, these spots will almost disappear and be replaced by pure white or lovely pink.
The prospect of survival is not optimistic. As an endangered animal under national key protection, the survival prospect of Chinese white dolphins is not optimistic. At present, most Chinese white dolphins are distributed in the southeast coast, with a total number of about 6,000. The large population is divided into five categories, among which the population in the sea near Hong Kong is the largest, reaching 2,500. The smallest population in Xiamen sea area is only 80. Judging from the current situation, the population of these Chinese white dolphins is declining every year, and the downward trend is about 2.46%. Therefore, the protection of Chinese white dolphins is imminent, which requires us to continuously reduce the pollution to the ocean and protect the marine environment.
