Phrynohyas resinifictrix

The Amazon Milk Frog is rather large for a tree frog. It is about 2.5 inches in length. Its body is light blue, blue-green or gray with black and brown banding covered with white and dark spots and bumps. As juveniles their patterning is more contrasting and then fades some with age. The given name "milk frog" comes from a white substance they secrete through the skin when threatened. This substance is poisonous to potential predators.
