Check the head shape: many venomous snakes have a broad, triangular head
Look for slit-like pupils: some venomous snakes have vertical pupils
Notice the presence of heat-sensing pits: pit vipers have small pits between the eye and nostril
Observe the body pattern: some venomous species have distinctive bands, diamonds, or hourglass markings
Examine the tail: rattles on the tail indicate a rattlesnake
Watch the behavior: venomous snakes may be more defensive, but behavior alone is not reliable
Check the location: learn which venomous snakes live in your area
Look at the scales above the head: some venomous snakes have smaller head scales, but this is not a safe standalone test
Avoid relying on color alone: color patterns can be misleading
Do not handle or approach the snake to identify it
Treat any unknown snake as venomous
Use a local field guide or wildlife expert for identification
If bitten, seek emergency medical help immediately
