Dyeing Poison Arrow Frog

From The Smithsonian Institute:


Poison arrow frogs are known for their beautiful colors. These colors are used as warnings to predators that they are poisonous (their poisonous defense evolved to ward off predators.) Some scientists think that the reticulated pattern of the frogs also act as camouflage among the forest shadows. This idea is not the norm.
