The living habits of giant salamander

Giant salamanders generally hide in mountain streams between the rocks, caves located below the water surface. At night, it stays quietly in the stone pile at the mouth of the beach. Once it finds prey passing by, it will suddenly attack. Because the teeth in its mouth are sharp and dense, it is difficult for prey to escape after entering the mouth. Baby fish have a strong ability to resist hunger, feeding in cool water for two or three years without eating will not starve to death. It can also overeat, gaining a fifth of its body weight with a full meal. When food is scarce, there will be cannibalism of the same kind, and even eggs to satisfy hunger. Hiding at ordinary times, like to put the color of the body and the surrounding stones, lest natural enemies find it.

Giant salamander is mainly distributed in Asia. Chinese giant salamander is distributed in other provinces except **, Xizang, Inner Mongolia and Taiwan. It is mainly produced in mountain streams of Yangtze River, Yellow River and middle and upper reaches of Pearl River.

The natural distribution of Chinese giant salamander is mainly concentrated in five regions in China: Zhangjiajie, Jiangyong, Yueyang in Hunan Province and Wuyi Mountain in Fujian Province in Xiangxi Autonomous Prefecture; Fangxian, Shennongjia, Guifeng Mountain in Macheng and Tiantangzhai in Luotian in Hubei Province; Hanzhong, Ankang and Shangluo in Shaanxi Province; Zunyi in Guizhou Province and Yibin, Xingwen, Weiyuan Hulukou and Bazhong Nanjiang in Sichuan Province; and Jing 'an in Jiangxi Province. Others are distributed sporadically in Hefeng, Lichuan, Enshi, Liuzhou, Yulin, Tianshui [4] and Wen County in Hubei Province, Luanchuan County, Lushi County, Hao County, Baotianman in Nanyang Neixiang, Yuanqu County in Shanxi Province, Qingyuan County in Zhejiang Province, Qiandongnan County in Guizhou Province, and Tianchi in Fenghuang Mountain in Chaozhou City. Among them, Jing 'an County was the first to issue an announcement to protect giant salamander in China since 1970s, and to establish the first national giant salamander nature reserve and the first national baby fish research institute. In 2001, the giant salamander was designated as the mascot of the county. Jing 'an County has the leading technical achievements in artificial breeding of giant salamander in China. It has passed the identification of relevant experts of Chinese Academy of Sciences and has the technical conditions for large-scale development and utilization of giant salamander. In August 2005, it was awarded the title of "Hometown of Chinese Baby Fish" by China Aquatic Products Processing and Circulation Association.

According to statistics, giant salamander natural resources reserves of about 90,000 tail, to hilly mountain resources for more, in economically developed areas due to the intensification of industrial pollution, resources are more insufficient. Daba Mountain District in Nanjiang County, Bazhong City, Sichuan Province, with high mountains and dense forests, Daba Mountain and no industrial pollution, is the best environment for giant salamander to survive.

Giant salamander nature ferocious, carnivorous, aquatic insects, fish, crabs, shrimp, frogs, snakes, turtles, rats, birds and other food. The predation mode is "waiting for rabbits." Its teeth can't chew, it just gulps down food and slowly digests it in its stomach.

Female salamanders lay eggs in July and August every year. The eggs are laid in rock caves. Each salamander lays more than 300 eggs. The rest of the rearing tasks are handed over to male salamanders. The male salamander bends the body into a semicircle and surrounds the eggs so as not to be washed away by water or suffer from enemies until the young salamander hatches 2 to 3 weeks later. After 15 to 40 days, the small "baby fish" disperses and lives, and the male salamander is willing to leave. The giant salamander's life span is also the longest among amphibians, and it can live as long as 130 years under artificially raised conditions.
