Description

Its maximum length is usually around 60-90cm. It has a long body, with a flat oblong trangular head differentiated from the body, with small scales. Its nostril scale is also triangular. [4] It was found to exhibit the largest attack acceleration among snakes, about 18g.[5]

Geographic range

The type locality given is "Fan-si-pan mountains, Tonkin, Indo-China"[2][6] (=Mount Fansipan).[3] It is currently known from several provinces in Vietnam (Lao Cai Province, Ha Giang Province, Quang Binh Province, Hue City, Lang Son Province).[1] The only Chinese record is from Ruyuan Yao Autonomous County in northern Guangdong and was originally described as a new species, Ceratrimeresurus shenlii.[1][2]
