Poison dart frogs are small, brightly colored amphibians found mainly in the tropical rainforests of Central and South America. They are known for their vibrant skin colors, which can range from yellow to blue, and serve as a warning to predators about their toxicity. These frogs get their poison from the insects they eat, such as ants and termites. The toxins in their skin can be harmful or even deadly to other animals. Indigenous people have historically used the frogs' poison to coat the tips of their blow darts for hunting, which is how they got their name. Despite their toxicity, poison dart frogs are popular in the pet trade due to their striking appearance.
