Reptiles
Venomous or harmless?
Most snakes in 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 giurza and the Caucasian viper, 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.

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.

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 and head shape often help, but they are not universal.
No. It is a legless lizard: it has eyelids and an ear opening. The profile shows how it differs from water snakes.
Giurza (largest and most dangerous) and the Caucasian viper (west, often confused with the grass snake). Then the rest of the venomous guide.
Often not. Use the atlas to compare, and if there is a bite — call 112. Do not wait on identification.
