According to the US media, the Mexican salamander is a kind of extreme survival. When the salamander loses a leg, a tail, or part of the heart, it can grow back without leaving any scars. But now this tenacious creature is on the verge of extinction.
According to the US quartz financial website reported on June 13, the Mexican salamander is also a paradox of environmental protection: this iconic creature is mexico's national symbol, and it has become a favorite pet of people around the world due to its ease of breeding in aquariums. But in the only remaining natural habitat of the Mexican salamander, the Hodgmirco Canal around Mexico City, pollution and water scarcity make it difficult to find.
As the wetlands disappeared, the Mexican salamander also gradually disappeared. When the first count was made in 1998, there were about 6,000 Mexican salamanders per square kilometre. But when Luis Samblano, an ecologist at mexico's National Autonomous University, counted again in 2015, there were only 35 Mexican salamanders per square kilometer.
The sharp drop in numbers also threatens mexican salamanders living in aquariums and laboratories around the world.
