The World’s Largest Amphibian Is Being Bred To Extinction

The world’s largest amphibian is the Chinese giant salamander, which can grow up to 2 meters in length. They were once common in rivers across southeastern China. But today, most are found in commercial farms, which breed them to satisfy growing demand from the luxury food market. The Chinese government encourages the release of farm-raised individuals in an effort to augment wild populations, but through DNA research scientists were able to discover that wild salamanders could be separated into five distinct genetic groups. In comparison, farm-raised salamanders were genetically homogenous. Any release of farm-raised salamanders risks muddying the genetic waters, potentially causing a distinct salamander species to become extinct through crossbreeding. If the wild populations go extinct the world will lose all five species. This video was produced by YT Wochit News using
