What is the largest species of amphibian?

The largest species of amphibian is the Chinese giant salamander (Andrias davidianus), which can grow up to 1.8 meters (5.9 feet) long. These aquatic salamanders are native to the Yangtze River and other parts of China. They are critically endangered due to habitat loss, pollution, and over-exploitation for traditional medicine and the pet trade. Despite their large size, Chinese giant salamanders are slow-moving, feeding on a diet of fish, insects, and other small animals.
