Li Min introduced

At present, there is no unified statement in the field of scientific research. Some organs of Chinese white dolphins such as navigation, positioning, or sonar system have problems, so that it cannot accurately distinguish the direction.

Some people think that Chinese white dolphins cannot ensure daily normal behaviors such as predation because of the degradation of physiological function, so it enters the river alone.

At present, such statements are speculated, but no matter what, it is normal for birth, sickness, and death.

Li Min said

It is not uncommon for Chinese white dolphins to enter the river by mistake

There are similar cases in Guangdong in the past year

The team is currently using the scene of Liuxihe
