Their bright colors are a warning to predators, a clever trick called aposematic coloration. Unlike many frogs, poison dart frogs don't have webbed toes, so they aren't good swimmers and spend their time hopping around the forest floor. Their diet mostly consists of termites and ants giving them the nutrients they need to survive. They catch animals by using their long stick tongue which is ⅓ of their body and their excellent eyesight. A poison dart frog is very social and often stays in pairs or small groups.
As the environment gets drier, they may develop webbed feet allowing them to stay in water to keep their skin soft and moist. Staying in water may also protect them from new predators such as birds as their coloring fades and their venom weakens. Their tongue may also get longer to access more food from further distances as their food population decreases.
