Snakes by State
Snakes by state vary in range, color, pattern, size, and habitat. Use this educational guide to learn which species may occur near you, then compare more than one feature before reaching a possible identification.
Identify from a distance
Do not approach, touch, trap, or handle a snake to identify it. A clear photo taken from a safe distance, the location, visible pattern, and body shape may help narrow the possibilities, but a photo or online guide cannot guarantee an identification. Leave unfamiliar snakes alone and give them space.
How to use this guide
Compare multiple traits
Look at pattern, body shape, head markings, habitat, and range. Color alone is not enough for a reliable identification.
Stay cautious
If you remain unsure, keep your distance and contact a local wildlife agency or an independent volunteer listed in the directory.

If someone may have been bitten
- Move away from the snake and seek emergency medical attention immediately.
- Call 911. Do not drive yourself to the hospital.
- Do not try to catch, handle, or kill the snake.
- If it can be done safely from a distance, a photo may help medical personnel.
