Blue poison dart frog

Dendrobates azureus is a medium-sized frog that weighs approximately 8 grams. It grows between 3 and 4.5 cm in length and has a typical lifespan of 4–6 years in the wild. Its bright blue skin serves as a warning to predators. Its colour is also usually darker around its limbs and stomach. The glands of poisonous alkaloids located in the skin serve as a defense mechanism to potential predators.
