Different frog species have different methods of protecting themselves from predators, such as attempting to flee, swelling up or playing dead. Other species use their skin color to either blend in with their surroundings or warn predators that they are toxic.

Due to the small, weak physical nature of frogs, fighting back when attacked is rarely an option. As a result, frogs have evolved some very useful traits that allow them to survive. Many frog species that reside in the rain forests of the Americas possess glands that secrete toxins through their skin. Some toxins make the frogs taste really bad, while others can cause paralysis, nausea and swelling. The alkaloid toxin secreted by the golden poison frog is regarded as one of the most-fatal poisons in the world.
