Poison Azureus Frog 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 color 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. These poisons paralyze and sometimes kill the predator. The black spots are unique to each frog, serving as an identification tool. Each foot contains four toes which each have a flattened tip with a suction cup pad used for gripping. This species of frog is also identifiable by a hunch-backed posture. Physical appearance also differs with the sex of the animal. Females are larger and about half a centimeter longer than males, but males have larger toes. The tips of the toes in females are round, while males have heart-shaped tips. Tadpoles vary greatly in appearance from adults. They have a long tail, about 6 mm, with a total length of about 10 mm. They lack legs and have gills instead of lungs.
