How to Choose
When selecting a snake to learn about or encounter, consider factors such as the snake’s venomous status, habitat, size, and behavior. Non-venomous species like the Eastern Ratsnake or Garter Snake are generally safer and more common in residential areas, while venomous snakes like Copperheads or Rattlesnakes require caution and respect.
