There are several poisonous snakes in Xinjiang.

1, intermediary. Agkistrodon intermedia is a reptile belonging to Agkistrodon, which is distributed in Russia and Mongolia in Central Asia and Shaanxi, Inner Mongolia, Shaanxi, Gansu, Qinghai, Ningxia and Xinjiang in Chinese mainland.

Living in the plains, hills and mountains with large topographic relief at an altitude of 620-2400 meters, especially in foothills, wheat fields, roadsides, gravel piles, cemeteries, crevices, lush pastures and bushes, and also living in desert and semi-desert areas. Summer and autumn are its peak seasons. When it is hot, it is active in the morning and evening, and quiet at noon. Cold-tolerant, hibernating gradually at the end of 10, and stinging in April of the following year.

2. extreme north. Most of them live in forest areas and grassland meadows in temperate and cold regions. Broad-leaved forest, coniferous forest, mixed forest and swamp. Take root caves or under rocks as their hiding places. A mountain with a vertical distribution of up to 2700 meters. Among all terrestrial snakes, the northern viper is the most widely distributed.

The living area extends from Scandinavia to central France and eastward to the Pacific coast of Russia. It is the only snake that appears in the Arctic Circle. China is mainly distributed in Jilin (Changbai Korean Autonomous County, Antu County and Fusong County in Changbai Mountain) and Xinjiang (Altay and Fuhai).

3. Grassland. Living in grasslands and mountainous areas (300 ~ 3000 meters above sea level), it is common in sparse woodlands, reeds and relatively open steppes, especially in the environment where there are many locusts, rat holes and wormwood. Activity at night, hiding in caves or crevices during the day. When it is hot in summer, it is active before 10 hour and after 16 hour, and it can "shout" when it is frightened; Cloudy days are also very active during the day.

Lizards in spring, locusts, mice, bees or spiders in summer. Young snakes eat lizards. Stings occur at the end of March and the beginning of April every year, and enter at the end of 10 or10, and most of them gather in squirrel caves or other crevices for the winter. Viviparous, born in August, once born 1 ~ 6 babies, up to 17 babies. ?

Extended data:

distribution range

Although there are snakes on the earth except the north and south poles, most warm-loving snakes are distributed in tropical and subtropical regions, and the number and species of snakes in temperate and cold regions are few. In China, cobras that are most afraid of cold are only distributed in the south of the Yangtze River.

South China is the most; However, Agkistrodon halys adapted to lower temperature are mainly in the north, few in the south of the Yangtze River, and almost none in South China. Liu Zongyuan, one of the eight masters in Tang and Song Dynasties, wrote the famous "Snake Catching Theory", which is about the poisonous snakes in Yongzhou (now Lingling) in subtropical Hunan. ?

About a quarter of the more than 200 species of snakes in China are endemic to China. These snakes are widely distributed in China, but mainly distributed in the Oriental boundary south of the Yangtze River, showing a distribution trend and characteristics of increasing species from north to south.

Among them, Fujian, Yunnan and Guangxi Zhuang Autonomous Region have the most species (85 ~ 100), followed by Guangdong, Guizhou, Hunan, Sichuan, Hainan, Anhui and Zhejiang Province (60 ~ 76). There are fewer species in Palaearctic realm (
