The Mission golden-eyed tree frog or Amazon milk frog (Trachycephalus resinifictrix) is a large species of arboreal frog native to the Amazon Rainforest in South America. It is sometimes referred to as the blue milk frog. It was first discovered along the Maracanã River in Brazil. This species was previously within the genus Phrynohyas, which was recently synonymized with Trachycephalus.
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.
The “milk” in the common name comes from the milky fluid these frogs excrete when stressed.
Trachycephalus resinifictrix is commonly found in captivity. They are relatively easy to care for, but require a significant amount of space, humidity, and regular cage maintenance to ensure a clean healthy environment for the frog.
