Key identifying features

The Long-Nosed Viper is identified by a distinctive soft, upward-pointing horn or projection on the tip of its snout, a broad triangular head clearly distinct from the neck, keeled scales, and a bold zigzag or wavy dorsal stripe running the length of the back.

Coloration & pattern

Base coloration varies from gray to brown or reddish-tan, with males often showing more muted, grayish tones and females tending toward warmer brown or reddish hues. A dark, continuous zigzag band runs down the spine, and a dark stripe often extends from the eye to the corner of the mouth, aiding camouflage among rocks and leaf litter.

Head, eyes & scales

The head is broad and triangular, clearly wider than the neck, a hallmark viper trait. The most distinctive feature is the soft, fleshy, upturned nasal appendage at the snout tip, unique among most European vipers. Eyes show vertically elliptical pupils. Scales are strongly keeled, giving a rough, textured surface.

Size & body shape

This is a moderately stout-bodied snake with a thick midsection tapering to a short tail, consistent with an ambush-hunting body plan rather than one built for speed.

Range & habitat where you'll see it

Found across parts of the Balkans, Southeastern Europe, and the Middle East, this species favors rocky hillsides, scrubland, and open woodland at various elevations, often basking on rocks or hiding among vegetation and stone piles.

How to tell it apart from look-alikes

The soft nasal horn is the single most reliable feature distinguishing this species from other similarly patterned European vipers, most of which lack any snout projection. Body shape, keeled scales, and zigzag patterning are shared broadly among related vipers, making the nasal appendage the key diagnostic trait when present and visible.
