The giant leaf frog, Phyllomedusa bicolor, also known as Kambo, Kambô, Cambô, and Sapo Verde, is a hylid frog.

Distribution[edit]

It is found throughout the Amazon Rainforest of northern Bolivia, western and northern Brazil, southeastern Colombia, eastern Peru, southern and eastern Venezuela, and the Guianas. Occasionally, it is also found in the riparian forest area of the Cerrado, a vast tropical savanna ecoregion of Brazil.

The IUCN endangered species database lists them in the "Least Concern species" category for now, in view of their current wide distribution and large population.

Description[edit]

The giant leaf frog, Phyllomedusa bicolor, is nocturnal and hunts small insects, which explains its arboreal locomotion. It has been found emitting its territorial or mating "song" in trees in tropical humid forests at heights greater than 2 metres (6.6 ft) above water near rainforest waterways.[2] Biologists report finding leaf-nests of this species approximately 2 metres (6.6 ft) above forest pools.[3] When the eggs hatch from these nests, the tadpoles fall into the water, where they continue the development into adult frogs. Tadpoles develop in mass in seasonal wetlands. They are also found in riparian forest areas of the Cerrado. The skin secretion of the frog contains deltorphin, deltorphin I, deltorphin II and dermorphin.[4][5][6]
