TED-Ed: Why don't poisonous animals poison themselves? - Rebecca D. Tarvin

The video explores how animals like the bombardier beetle, jellyfish, snakes, and poison dart frogs use toxic chemicals for defense. It explains two main strategies: storing toxins securely or evolving resistance. Bombardier beetles store poison in separate chambers, while snakes and frogs develop biochemical resistance. The evolutionary arms race between toxic animals and their predators is highlighted, showing how both evolve over time to survive and thrive.
