About Ptyas major (Günther, 1858)
Ptyas major (Günther, 1858), commonly called the Chinese green snake, is a slender, medium-sized snake. Its average total length is 75–90 cm (2½-3 feet), and it can occasionally grow up to 120 cm (4 feet). The species is bright green on its upper body, with greenish-yellow ventral scales. All dorsal scales are smooth, except that males have keels on several mid-dorsal scale rows. Some individuals have scattered black spots on their dorsum, and preserved dead specimens often turn blue.
The Chinese green snake is distributed in central and southern China (including Hainan, Henan, Gansu, Anhui, Sichuan, Fujian, Guangdong, Guangxi, Guizhou, Hunan, Hubei, Jiangxi, Jiangsu, Shaanxi, Zhejiang, and Hong Kong), Taiwan, northern Vietnam, Laos, and Bangladesh (specifically Sylhet and Ratargul Swamp Forest). It inhabits humid forests and farmland.
This species is diurnal and semi-arboreal. It has a mild temperament and rarely bites when encountered.
The Chinese green snake is oviparous. Females lay clutches of 2 to 16 eggs, and young snakes hatch from the eggs after approximately two months.
