The sparkling colors on certain #amphibians, reptiles, and even insects are not an invitation but a warning. Poison #frogs, for example, don’t inject their toxins into prey (like venomous snakes do), but if a predator tries to snack on one of these jewels of the rain forest, they will be in for a sore surprise. The same is true for vibrant monarch butterflies, which eat #poisonous toxins for every meal in the form of milkweed. A good rule of thumb is: Bright colors? Beware! #PoisonDartFrog #animals #nature #sandiegozoo
