September 20th is the eighteenth National Science Popularization Day. It coincides with the twenty -fourth National Love Day. A festive popular science activity about dental protection and teeth was held on September 18 in the Changlong Ocean Kingdom of Zhuhai.

At the event site, a number of tourists turned into "tooth protection officers". Under the leadership of the science science lecturer, they observed the specimens of marine animals to understand the special functions of the teeth of marine animals.

"Shark's upper and lower jaws have a few rows of teeth, and those in the front row are working teeth to bite the meat. The latter is a completely shaped teeth to replace those damaged or shed work teeth." Popular science lecturers are while lecturers on the side. Guide children to observe the tooth specimens of marine fish such as sharks, catfish, and shells, and talk about the predation function of different teeth of marine fish.

According to Lecturer Zhuhai Chimelong, although animals cannot brush and wash teeth like humans, animals have their own set of ways to protect their teeth. For example, the shark can protect the oral health by changing teeth, and the number of teeth replaced in life is more likely to be as high as tens of thousands; and the mouth of the great white shark will have rows of sharp teeth. Instead, the front row teeth are replaced; a large lemon shark will fall off at about 30 teeth in a week; the cannon bomb fish teeth are extremely sharp. They can polish their teeth by eating corals and shells to prevent teeth from growing and piercing their jaw.

In addition to "self -learning" in terms of teeth and teeth, the teeth of animals also have a mystery. In the perspective of science science lecturers, the biggest effect of unicorn whale teeth may be puppets and feel the environment. In the season of unicorn whale mating, the long and beautiful males are often favored by females. When they encounter competitors, male unicorn often uses long teeth to "duel". Coincidentally, the long teeth of the walrus are also the weapons of their fighting. The male marchica will fight each other for the mating right, or it may be to crowd the space on the coast to fight each other. The long teeth of the walrus are enough to pierce each other's skin.

"This activity not only intuitively observed animal teeth, but also learned some knowledge of animal teeth through the patient explanation of the lecturer. Children have a lot of gains. I hope that there will be a chance to participate in such activities in the future." A parent from Guangzhou said Essence Through field observations and experiences, friends and young friends walk into the world of animals together. Not only does the animal dental science popularize the secrets of marine animals, but also pass on the good habits of love to care for teeth advocated by the teeth.

It is reported that the Changlong Ocean Kingdom of Zhuhai will hold a series of animal special protection activities every year, such as "World Whale Shark Drive the World of Whale Whale" and "Chinese Panda Day to Watch Giant Panda together" and other characteristic science popularization activities. Observation and contact, let tourists understand the significance of animals and natural protection in addition to playing.
