Certain physical characteristics can help identify venomous snakes, but approaching a snake simply because of its appearance is not safe.
Many viper species have a broad, triangular-shaped head. However, this trait is not always evident in venomous snakes like cobras and kraits.
In some venomous snakes—particularly many vipers—the pupils may appear vertical. However, assuming a snake is venomous based solely on its pupils is not reliable.
When threatened, a cobra can raise the front part of its body and spread its hood. Distinctive markings may also be visible on the hood.
Many venomous snakes possess specialized teeth designed to deliver venom. These fangs help inject venom into the prey's body.
Identifying a snake based on bite marks is not a reliable method. Treat any snakebite as potentially venomous and seek immediate medical attention.
Pit vipers have a specialized pit located between the eye and the nostril. This organ helps sense surrounding heat and is useful for locating prey.
Some venomous Indian snakes feature distinctive body patterns. Examples include the white bands on a krait and the blotchy pattern on a Russell's viper.
When threatened, some snakes may emit loud hissing sounds or other specific noises. If you hear such sounds, immediately move away from the snake.
Do not attempt to catch a snake or get close to identify it. Maintain a safe distance, and in the event of a bite, go to a hospital or seek professional medical help immediately.
