Kaulback's Lance-Headed Pit Viper

Kaulback's Lance-Headed Pit Viper inhabits rugged montane forests spanning parts of northern Myanmar, southwestern China, and northern Vietnam. It is named in honor of British explorer and naturalist Ronald Kaulback, who conducted expeditions in the region.

As with several montane Protobothrops species, it remains relatively poorly studied due to the remote and difficult terrain it inhabits.

• Olive to brownish-green body with darker irregular blotching
• Elongated, lance-shaped head profile giving rise to its common name
• Vertical pupils and heat-sensing pits between eye and nostril
• Moderately slender to moderately stout body
• Keeled scales along the dorsum
• Distinguished from related Protobothrops mainly by head shape and montane distribution

Found in montane forests and rugged terrain across northern Myanmar, adjacent southwestern China, and northern Vietnam, typically at moderate to high elevations in humid forest habitats.

Believed to be primarily nocturnal, foraging for small mammals and other vertebrates on the forest floor. Detailed reproductive data are limited, though it is presumed oviparous like related species.
