Differences Between Venomous and Nonvenomous Snakes
So, what’s the big difference between venomous vs nonvenomous snakes?
-
Venomous Snakes: These snakes have venom (poison) inside their fangs. When they bite, they can inject venom into their prey (or anyone who gets too close!). The venom helps the snake catch food or defend itself.
-
Nonvenomous Snakes: These snakes don’t have venom. If they bite, it doesn’t hurt much, and they usually bite out of fear or to protect themselves. Nonvenomous snakes often use their muscles to squeeze their prey instead of relying on venom.
✅ How to Identify Venomous vs Nonvenomous Snakes (Visual Guide)
Learning how to identify venomous vs nonvenomous snakes is super important! Here are some easy ways to spot the difference:
-
Head Shape: Venomous snakes usually have a triangular or arrow-shaped head. Nonvenomous snakes have more rounded heads.
-
Pupils: Look at the snake’s eyes! Venomous snakes typically have slit-shaped pupils, while nonvenomous snakes usually have round pupils.
-
Fangs: This one’s tricky, but venomous snakes have fangs to inject venom, while nonvenomous ones don’t.
