Do not rely on color, pattern, or head shape alone
Check whether the snake has a rattle, hood, or other species-specific feature
Look for heat-sensing pits between the eye and nostril in pit vipers
Observe the pupil shape only as a clue, not proof
Use a local field guide for your region’s venomous species
Compare the snake’s body markings with verified identification resources
Note the tail shape and any distinctive tail markings
Keep a safe distance and do not handle the snake
If unsure, assume the snake is venomous
Contact local wildlife authorities or a snake expert for identification
If bitten, seek emergency medical help immediately
