Introduction
The Amazon milk frog was initially described as Hyla resinifictrix by Goeldi in 1907. After several taxonomic changes, the species is now classified under the genus Trachycephalus. It is a nocturnal arboreal species that inhabits the canopy of primary rainforests, where it reproduces in phytotelmata (exclusively tree holes).
Females produce milk in special cutaneous glands located on their backs. Tadpoles climb onto the female's back to feed on this maternal milk. The milk contains proteins, lipids, and carbohydrates, as well as bioactive compounds that are highly beneficial for the tadpoles. This milk also contains toxic substances used for defense against predators.
