How to Identify the Montpellier Snake (Identification Guide)

Key identifying features

The Montpellier Snake is a large, powerfully built but streamlined colubrid best known for the pronounced ridges above its eyes, which give it a distinctive stern or hooded facial expression. It is a fast, alert, diurnal hunter that relies heavily on vision, and it will often raise its head and neck off the ground when alarmed, somewhat like a cobra, though it lacks a true hood. This defensive posture combined with its facial ridges makes it fairly easy to recognize once seen.

Coloration & pattern

Adults are typically gray, olive, or grayish-brown above, often appearing fairly uniform but sometimes showing faint darker spotting or a subtly mottled texture, especially in younger individuals. Juveniles tend to show a more distinct pattern of dark blotches or spots on a lighter background, which becomes less obvious as the snake ages into a more uniformly toned adult. The belly is generally pale yellowish or cream, often unmarked.

Head, eyes & scales

The most diagnostic head feature is the pronounced bony ridge above each eye, creating a heavy-browed look that is unusual among European and North African colubrids. The eyes themselves are large with round pupils, positioned somewhat forward-facing, contributing to strong binocular vision useful for a visually-oriented hunter. Dorsal scales are smooth to weakly keeled, giving a moderately sleek surface texture.

Size & body shape

This is one of the larger colubrid species in its range, with a long, muscular yet still relatively slender body built for speed. The tail is long, and the overall proportions favor rapid overland movement rather than climbing or burrowing. Its size alone, combined with the brow ridges, often sets it apart from smaller sympatric snakes.

Range & habitat where you'll see it

The Montpellier Snake favors dry, open habitats including scrubland, rocky hillsides, olive groves, and coastal maquis across southern Europe and North Africa. It is most active during warm daylight hours, often seen basking in open areas or moving rapidly across paths and clearings, and it readily climbs low shrubs when pursuing prey or escaping disturbance.

How to tell it apart from look-alikes

The pronounced supraocular (brow) ridges are the single most reliable feature distinguishing the Montpellier Snake from other large regional colubrids, most of which have smoother, less pronounced brow contours. Its defensive head-raising and neck-flattening display, while lacking a true cobra-like hood, is another useful behavioral clue when combined with its size and habitat. Round pupils and an elongated, non-triangular head shape help separate it from vipers found in overlapping arid habitats.
