Some animals use toxins for predator defense as a way to deter predators from attacking them. They may produce or secrete toxins that are poisonous or irritating to predators when ingested or touched. These toxins can cause harm or even death to predators, serving as a form of self-defense. Examples of animals that use toxins for predator defense include poison dart frogs, certain species of snakes, and some insects like the monarch butterfly.
