Why do some animals produce poison?

Some animals produce poison as a defense mechanism or to subdue prey. Poison helps animals avoid predators or stop them from getting eaten by causing sickness, pain, or even death. For example, many frogs, such as the poison dart frog, produce toxins that make them unappealing to predators. Similarly, some snakes, spiders, and insects produce venom to immobilize or kill their prey, making it easier for them to consume. These toxins are an evolutionary advantage that helps them survive and reproduce in their respective environments.
