Reptiles
Venomous or harmless?
Most snakes in the Republic of Georgia are harmless. A vertical pupil and a triangular head often point to vipers, but no rule is universal.
ID
No rule is universal
Telling venomous from harmless by a photo is risky. A species profile is better: marks, habitat, region. This page gathers common mix-ups — not a field guarantee.
Start with the Levantine viper and the Caucasus viper (Vipera kaznakovi), then the other venomous species. Water snakes, the smooth snake, and the glass lizard (a lizard) are often mistaken for vipers.
Practice
Next: which snake is it?
This guide is field identification. Photo practice lives on a separate quiz — ten frames, four names.
Signs
What people look at — and why it is not enough
No single sign proves a snake is venomous. If you are unsure, keep your distance and compare with the atlas.
- 01
Pupil
Vipers often have a vertical pupil; many harmless snakes have a round one. It is not always visible and it changes with light.
- 02
Head shape
A triangular head is typical of vipers, but a harmless snake can flatten its head when threatened.
- 03
Lookalikes
The grass snake can resemble the Caucasian viper; the glass lizard resembles a snake. Compare the pairs below and open the profiles.
- 04
When you do not know
Do not catch it. Do not kill it. Most are harmless. The venomous list is in a separate guide.
Venomous
Giurza → Caucasian viper → other venomous snakes
Start with the most dangerous, then the western forest viper, then the rest of the catalog.
Mix-ups
Pairs that are often confused
Water snake and viper; glass lizard and snake; Montpellier snake and giurza. Each side opens a profile.
Myths
ID myths that cause bad calls
Photo ID and street advice fail often. Keep distance; use profiles.
Myth: Vertical pupil means it is always venomous.
Reality: Many vipers show a vertical pupil, but the cue fails in poor light and is not a field guarantee. Identify the species.
Myth: A triangular head proves a viper.
Reality: Harmless snakes can flatten the head when threatened. Head shape alone is not enough.
Myth: The Montpellier snake is the Levantine viper.
Reality: Malpolon is rear-fanged and moderate risk; the Levantine viper is a High-risk front-fanged viper. They are different animals.
Myth: The glass lizard is a venomous snake.
Reality: It is a legless lizard (eyelids, ear opening). None of the glass-lizard comparison species is venomous on this page.

FAQ
What people ask about ID
Short answers — the decision lives on the profile.
The reliable path is species identification, not a single cue. Pupil shape and head outline often help with vipers in Georgia, but light, angle, and defensive flattening mislead. Compare atlas profiles and habitat; if bitten, call 112 before you finish identifying.
No. The glass lizard is a legless lizard: it has eyelids and an ear opening, which snakes lack. People often search it as a “large snake.” Open the glass-lizard comparison guide and the species profile — it is not venomous on this atlas.
Learn the Levantine viper first — largest and highest risk in Georgia — then the Caucasus viper in western Colchic forest, often confused with grass snakes. After that, open the full venomous guide for the remaining vipers and the rear-fanged Montpellier snake.
Often not with certainty. Use the atlas to compare marks and lookalikes. If there is a bite, call 112 immediately — do not wait on a perfect ID. A distant photo can help later only if it is safe to take.
