Key identifying features
The Palestine viper (Montivipera palaestinae) is a robust, medium-to-large viper reaching roughly 90-130 cm, with a thick body, short tail, and a distinctly triangular, wide head that is clearly separated from a comparatively narrow neck. Like other true vipers it has vertically elliptical (cat-like) pupils and keeled scales that give the body a rough, matte texture rather than a glossy sheen.
Coloration & pattern
Base coloration ranges from pale tan, olive-gray, or straw-yellow to light brown. Running down the back is a series of dark brown to almost black, roughly zigzag or wavy-edged blotches that may fuse into a broken chain-like band along the spine. Smaller dark spots are usually present along the flanks, alternating with the dorsal blotches. The underside is typically pale cream or grayish, sometimes flecked with darker spots near the edges.
Head, eyes & scales
The head is broad and triangular, covered in small, irregular scales rather than large plates, which is typical of vipers. A dark, often V- or arrow-shaped marking or streak may be visible on top of the head, and a dark stripe frequently runs from behind the eye toward the jaw. The eyes have vertical pupils and are moderately large, positioned toward the front-sides of the head. Body scales are strongly keeled, giving a dull, non-reflective appearance in the field.
Size & body shape
Adults commonly measure 90-120 cm, with some individuals exceeding 130 cm, making this one of the larger vipers within its range. The body is stout and muscular rather than slender, tapering to a short, thin tail. This heavy-bodied build, combined with the wide head, gives the snake a noticeably different silhouette from slimmer, non-venomous colubrids sharing the same habitat.
Range & habitat where you'll see it
The Palestine viper is found in Israel, the Palestinian territories, Lebanon, and parts of western Syria and Jordan, generally in Mediterranean climate zones. It favors rocky hillsides, scrubland, agricultural terraces, orchards, and areas near streams or springs, often at low to moderate elevations. It is frequently encountered near stone walls, brush piles, and cultivated land where rodent prey is abundant.
How to tell it apart from look-alikes
The Palestine viper can be confused with other regional vipers such as the nose-horned or Ottoman vipers, but it lacks any nasal horn or upturned snout scale, distinguishing it from horned species. Its zigzag dorsal pattern is generally less crisp and more blotch-like than the sharp zigzag of some European adders. Non-venomous colubrid snakes in the same region, such as whip snakes or rat snakes, have slender bodies, round pupils, large symmetrical head plates, and smooth or lightly keeled scales, contrasting with the viper's stocky build, vertical pupils, and rough keeled scales.
Frequently asked questions
What color is a Palestine viper?
It is typically tan, olive, or light brown with a series of dark brown zigzag or blotch markings running along the back and smaller spots along the sides.
How can I tell a Palestine viper from a non-venomous snake?
Look for a broad triangular head, vertical pupils, rough keeled scales, and a stocky body — features that distinguish it from the slender, round-pupiled, smooth-scaled colubrids found in the same region.
Does the Palestine viper have a horn on its nose?
No, it has a smooth, rounded snout without any horn-like projection, which helps separate it from horned viper species in the region.
How big does a Palestine viper get?
Most adults reach 90-120 cm in length, with a heavy, thick body and short tail.
Where in the landscape is the Palestine viper usually found?
It favors rocky hillsides, scrub, orchards, and agricultural terraces, often near stone walls or water sources at low to moderate elevation.
