The type locality for T. percarinatus is Guadun (formerly spelled as Kuatun), Wuyishan City (former Chongan County) in NW Fujian, China.[3]
The subspecies Trimerodytes percarinatus suriki is endemic to Taiwan[3] where it occurs in the whole country.[4]
T. percarinatus is a defensive snake that bites readily when caught, but it is not venomous.[4][5] It is a medium-sized snake, typically attaining a total length (including tail) of 70–90 cm (28–35 in), but may grow up to 110 cm (43 in).[5] An adult female usually lays 4 to 13 eggs,[1] but may lay as many as 25 eggs.[4]
T. percarinatus is found in NE India (Changlang District, Arunachal Pradesh), Myanmar (= Burma), Thailand, Laos, Vietnam, S China (Hainan, Zhejiang, Jiangxi, Fujian, Guangdong, Guangxi, Guizhou, Sichuan, Hubei), Hong Kong, and Taiwan.[1][3] It is an aquatic species associated with hilly areas.[1][5]
T. percarinatus preys on shrimps, frogs (including tadpoles), and fish.[4]
