The giant salamander is ferocious by nature and is a carnivore, feeding on aquatic insects, fish, crabs, shrimps, frogs, snakes, turtles, mice, birds, etc.

The giant salamanderusually hides in rocks in mountains and streams In the gap, the cave is located below the water surface. At night, they stay in the rock piles at the beach mouth, and once they find the prey passing by, they will make a surprise attack. The giant salamander's teeth cannot chew, it just swallows the food whole, and then slowly digests it in the stomach. Because of the sharp and dense teeth in its mouth, it is difficult for prey to escape after entering the mouth.
