How to ID a Poisonous Snake

In the United States, there are a few specific characteristics that can help you identify whether a snake is poisonous. It’s essential to observe these traits from a safe distance to avoid close encounters with potentially dangerous snakes.

  • Pupil Shape: Venomous snakes often have elliptical, cat-like pupils, whereas non-venomous snakes usually have round pupils. However, the coral snake is an exception with round pupils.
  • Head Shape: Many venomous species have a distinct triangular-shaped head since their venom glands are located on the sides, giving the head a broader appearance. Look for this feature when attempting to determine if a snake is venomous.
  • Color Patterns: While not a guaranteed method since many non-venomous snakes mimic the colors of their venomous counterparts, knowing the common color patterns helps.For instance, the coral snake has specific banding patterns that can be used for identification.
  • Behavior: Venomous snakes may display certain behaviors such as rattling their tails or adopting an aggressive posture. Rattlesnakes are a prime example of using tail rattles as a warning.

Here is a quick reference table for identifying some American venomous snakes:
