The white-lipped pit viper is a venomous pit viper species endemic to Southeast Asia.
Males are smaller than females. Generally, males grow up to 60cm long and females 81 cm long. Head scalation consists of 10-11 upper labials, the first partially or completely fused to the nasal. Head scales small, subequal, feebly imbricate, smooth or weakly keeled. The supraoculars are narrow with 8-12 interocular scales between them. Temporal scales smooth.
Midbody has 21 longitudinal dorsal scale rows. The ventral scales are 155-166 in males, 152-176 in females. The subcaudals are paired, 60-72 in males, 49-66 in females. The hemipenes are without spines.
Color pattern: green above, the side of the head below the eyes is yellow, white or pale green, much lighter than rest of head. The belly is green, yellowish or white below. A light ventrolateral stripe is present in all males, but absent in females. The end of tail is not mottled brown.
Its meals consist of birds, small frogs, and small mammals. This snake doesn’t strike and release its prey; like many arboreal snakes, it strikes and holds on to the prey item until it dies.
