How to Identify the Arabian Horned Viper (Identification Guide)

Key identifying features

The Arabian Horned Viper is recognized by a single, raised horn-like scale above each eye, a broad triangular head, and a pale sandy body coloration adapted to the desert dunes and gravel plains of the Arabian Peninsula.

Coloration & pattern

The body ranges from pale sandy yellow to light tan or grayish, with a series of darker, often squarish or rounded blotches running down the back and smaller spots along the sides. This pattern closely matches the open sand and gravel substrates of its habitat, aiding concealment.

Head, eyes & scales

The head is broad and triangular, clearly distinct from the neck, with the characteristic single horn-like scale rising above each eye. Body scales are keeled, and the snake is often found partially buried in loose sand with only the head exposed.

Size & body shape

Adults typically measure 40 to 60 cm, with a moderately stout body and a short tail, consistent with other horned desert vipers.

Range & habitat where you'll see it

Found across the sandy deserts and gravel plains of the Arabian Peninsula, including parts of Saudi Arabia, the United Arab Emirates, and neighboring countries, often in dune fields and open desert terrain.

How to tell it apart from look-alikes

The single supraocular horn is shared with the closely related Persian Horned Viper found further north and east; the two are best distinguished by geographic range, with the Arabian Horned Viper restricted to the Arabian Peninsula while the Persian Horned Viper occurs in Iran and adjacent regions.
