Coral is a group of tiny creatures, which is it? Coral? Coral is a coelenterate, generally living in groups, and a large number of corals live together. They can absorb calcium and carbon dioxide from seawater to secrete calcium carbonate, which is often called limestone, and finally completely calcify. This calcification process is a process from organic organisms to inorganic compounds, and it is also the formation process of coral reefs that we finally see. Because each coral body is very small, it is still very small after calcification, so the coral reefs we see are the result of calcification of millions or even millions of corals, which are constantly multiplied from generation to generation, and the old coral bodies are constantly covered with new ones, with different shapes and random combinations, and finally form the appearance of various handicrafts we see.
Huge coral reefs in ancient times would pay tribute to the royal family. Because the calcified coral reef is easy to break, it can keep its huge shape intact and is a world-class product. Moreover, because the main component of coral reefs is calcium carbonate, many corals forget to put them into the water after being picked up and become dull and dry. At this time, just remember to put them in the water for a while.
In addition, coral itself not only has ornamental value, but also has medicinal value in traditional Chinese medicine. Coral has been recorded in various ancient medical books, saying that it can improve eyesight, stop bleeding and remove blood stasis, and it also plays a role in endocrine regulation of beauty beauty and women. Many people wear red coral ornaments for a long time, which can not only improve their complexion, but also promote blood circulation and play a health care role. Although the effect is exaggerated, the jewelry made of coral is bright and lively, but not too ostentatious. Some red corals will show different colors according to the changes of air humidity and temperature, which are very magical and beautiful, and are deeply loved by girls of all ages.
