Living habits of giant salamander;
Giant salamanders are fierce carnivores, feeding on aquatic insects, fish, crabs, shrimps, frogs, snakes, turtles, rats and birds. The predation mode is "waiting for the rabbit". Giant salamanders usually live in the crevices of mountain streams, and their caves are below the water surface. At night, it stays quietly in the stone pile at the mouth of the beach. Once it finds its prey passing by, it will launch a surprise attack. Because the teeth in its mouth are sharp and dense, it is difficult for prey to escape after entering its mouth.
Giant salamander's teeth can't be chewed, just open its mouth and swallow the food, and then slowly digest it in its stomach. Giant salamander has a strong hunger tolerance, and it will not starve to death if it is put in cold water for two or three years. It can also overeat, and a full meal can increase one-fifth of the weight. When food is scarce, cannibalism will occur, and even eggs will be used to satisfy hunger.
