What is the world's largest amphibian, often active at night?

What is the world's largest amphibian, often active at night? The answer is the South China giant salamander. Andrias sligoi is currently regarded as the largest living amphibian and may reach approximately 1.8 metres in length.

This giant salamander is native to southern China, especially the Pearl River basin south of the Nanling Mountains. It is fully aquatic and inhabits freshwater environments.

The species is primarily nocturnal or most active during evening and nighttime hours. It hunts using smell, touch, and vibration-sensitive structures because its eyesight is poor.

For many years, the Chinese giant salamander was listed as the world's largest amphibian. Genetic research later distinguished the South China giant salamander as a separate species, making the older answer outdated. The correct species is not included among the supplied options.
