              Fascinating Facts

              Physical Characteristics

              Amazon milk frogs have bumpy skin and large toe pads for tree climbing. They are patterned in darker and lighter shades of brownish-grey. Females grow up to 3 ½ inches in length, while males grow up to 3 inches in length. Their scientific name, “Trachycephalus” refers to their rounded snout, which they use for pushing aside vegetation to hide amongst. They have large vocal sacs and can produce a loud call.


              Amazon milk frogs are primarily arboreal and are found in the tropical rainforest canopy in the Amazon Basin, in parts of Ecuador, Venezuela, Colombia, Peru, Bolivia, Guyana, French Guiana, Suriname and Brazil.

              Social Behavior

              Males will vocalize from a water-filled tree cavity on a clear night to better carry the sound of their call. They reproduce during the rainy season, with a clutch of 2000+ gelatinous eggs laid inside a tree cavity. The tadpoles will hatch within a day. Amazon milk frogs are nocturnal.
