Amazon milk frog (Trachycephalus resinifictrix)

It was first discovered along the Maracanã River in Brazil. This species was previously within the genus Phrynohyas, which was recently synonymized with Trachycephalus.The Amazon milk frog is a large arboreal frog native to South America. The "milk" in the name comes from the milky fluid the frogs excrete when stressed. These frogs are fairly large, reaching sizes of 2.5 to 4.0 in (6.4 to 10.2 cm) in length. Adult frogs are light grey in colour with brown or black banding, while juveniles will exhibit stronger contrasts. As they age, their skin develops a slightly bumpy texture.
