Turtles are the real giants in ancient books.

Speaking of turtles, we are all very familiar with them, and turtles, as relatives of turtles, often appear on our dining tables and have always been regarded as a great supplement by Chinese people. In fact, there is a very precious turtle in the world, even rarer than the national treasure giant panda. There are only three turtles in the world, and that is? Turtle? . Globally, Suzhou Zoo 1, Vietnam Tongmo Lake 1, Vietnam Xuanhan Lake 1. At present, this kind of animal is on the verge of extinction, because the existing three turtles are too old to live together, so it is difficult to reproduce, and the one that once lived in Suzhou Lake in China also died on April 20 19 13. What's going on here? Let's take a look with Bian Xiao.

Precious turtles, like many rare animals, were once widely distributed in the lower reaches of the Yangtze River and Taihu Lake basin in China. The ancients called them? What happened? . Later, with the continuous loss of natural habitats and the killing of human beings, the number of wild turtles became less and less. Since 1972, no wild turtles have been found in China, only a few are on the verge of extinction, and finally only two are left. In fact, the extinction of turtles has a lot to do with human beings. At first, people didn't know that this turtle was a new species, so they killed it in large quantities and ate it as an ordinary turtle. For a long time, this turtle has been mistaken for giant salamander or Chinese soft-shelled turtle, and it was not confirmed as a new species until after 2002 when it was on the verge of extinction. When Suzhou Zoo was built, there were dozens of turtles in the yard, but because the staff didn't know them, they were not effectively protected. Finally, only one turtle can live to be a hundred years old.

The only turtle left in Suzhou Zoo is male, and one turtle is not allowed to breed. Just as the staff were sad about the fate of the tortoise, good news came from the distant Changsha Zoo. A turtle in the park is confirmed as a turtle and can be sent to be paired with a turtle in Suzhou Zoo. After a long journey of1100km, the last two turtles in China finally met and knew each other. Unfortunately, although the zoo staff wanted them to continue their offspring through artificial insemination, the eggs they laid could not hatch successfully. This is because the male turtle in Suzhou Zoo is old and the sperm activity in the body is not high, which leads to the failure to hatch every time he lays eggs.

20 19, 19 On April 2, 2009, international experts and Suzhou Zoo staff conducted sperm collection and artificial insemination on the only remaining pair of turtles in China. Unfortunately, despite the 24-hour rescue, the mother turtle still didn't wake up and died unfortunately. ? This means that it has become impossible to breed turtles in China, because there is no female turtle except one male turtle at present, and the turtle race in China will end unless a new turtle population can be found in the wild.
