Key identifying features
Schultze's Pit Viper is a slender, arboreal green pit viper found in the Philippines, identifiable by its vivid coloration, prehensile tail, and the classic pit viper set of a broad triangular head, vertical pupils, and heat-sensing facial pits.
Coloration & pattern
The body is typically a rich green, sometimes with a yellowish or bluish cast, and may show faint darker speckling rather than bold banding. A pale lateral stripe often runs along the lower side of the body, more prominent in some individuals than others. The tail tip may show a slightly different, often reddish or brownish coloration in some individuals, a trait shared with several related green pit vipers. The belly is pale green to yellow.
Head, eyes & scales
The head is broad and triangular, clearly wider than the neck, with small fine scales covering it. Eyes are large with vertical pupils, aiding low-light activity, and a heat pit lies between each eye and nostril. Body scales are keeled, giving a faint roughness to the otherwise smooth green skin.
Size & body shape
The body is slender and laterally compressed, well suited to climbing, with a prehensile tail. Overall length is modest, consistent with related arboreal pit vipers in the region.
Range & habitat where you'll see it
This species inhabits forested and montane areas of the Philippines, often resting coiled on low branches, shrubs, or vines in humid forest understory and forest-edge vegetation.
How to tell it apart from look-alikes
Its green coloration with faint speckling, paired with a possible contrasting tail-tip color, helps separate it from other Philippine pit vipers with bolder crossbanding, such as the Broad-Banded Temple Pit Viper. Careful attention to subtle pattern differences and locality is often needed to distinguish it from closely related green pit vipers sharing its range. The triangular head, vertical pupil, and heat pit rule out harmless green tree snakes at a glance.
