Poison frogs are generally small species, about 0.75 to 1.5 inches (20 to 40 millimeters) in length.
Poison dart frogs are an excellent example of warning colorations. Dart frogs are very toxic and will most likely kill anything that tries to eat it. Unfortunately, the frog will also be killed if it is consumed by a predator. The very bright colorations make the frog easy to see and act as a warning to predators that the animal is poisonous. Most dart frogs lay eggs in humid soil where the adults sit on them to keep them moist. When the eggs hatch, the male carries the tadpoles on his back to a protected pool of water. Often the protected pool is rainwater that collects between the leaves of bromeliad plants.
