Differences between Poisonous Snakes and Non-Poisonous Snakes
There are several key differences between poisonous snakes and non-poisonous snakes that can help you identify and differentiate between the two.

Physical Characteristics
- Poisonous snakes often have triangular-shaped heads, while non-poisonous snakes have more rounded heads.
- Poisonous snakes typically have vertical pupils, while non-poisonous snakes have round pupils.
- Poisonous snakes may have heat-sensing pits on their faces, which non-poisonous snakes do not have.
- Some poisonous snakes have brightly colored or patterned markings, while non-poisonous snakes are more likely to have duller colors or patterns.

Behavioral Traits
- Poisonous snakes are more likely to exhibit defensive behaviors, such as hissing, rattling their tails, or striking when threatened.
- Non-poisonous snakes are more likely to try to flee or hide when confronted by a predator or human.

Venom
- Poisonous snakes have venom glands and fangs that they use to inject venom into their prey or predators.
- Non-poisonous snakes do not have venom glands or fangs and rely on constriction or other methods to catch their prey.

Effects of a Bite
- A bite from a poisonous snake can be potentially life-threatening and may require immediate medical attention.
- A bite from a non-poisonous snake may be painful and cause swelling, but is generally not life-threatening.
By being aware of these differences in physical characteristics, behavior, venom, and the effects of a bite, you can better identify and respond to encounters with snakes in the wild.
