life habit

Giant salamanders often lie in caves during the day and rarely go out for activities. In summer and autumn, they also have the habit of going ashore for food or sunbathing during the day. Giant salamanders usually go out at night and return in the morning, and live in a cave. Predation is mainly carried out at night, often waiting among the rocks at the mouth of the beach. When hunting animals pass by, they suddenly open their mouths to prey.

The giant salamander is suitable to inhabit the water with the water temperature of 3 ~ 23℃. Most large individuals live in deep water, and most small and medium-sized individuals live in shallow water. Most of the adult giant salamanders are solitary, and the young giant salamanders are often clustered in rocky crevices, and the optimum water temperature for their life is10 ~ 20℃.

The giant salamander often puts its head into the water to breathe, and its skin is also an important organ for gas exchange. In the water with high oxygen content, the giant salamander can lie on the bottom of the water for a long time without coming out to breathe. In the case of artificial feeding, put your nostrils out of the water every 6 ~ 30 minutes to breathe, and inhale for about a few seconds to several 10 seconds.
