Trimeresurus albolabris, the white-lipped pit viper or white-lipped tree viper, is a venomous pit viper species endemic to Southeast Asia. Its meals consist of birds, small frogs, and small mammals. This snake does not strike and release its prey; like many arboreal snakes, it strikes and holds on to the prey item until the prey dies.
