Family: Odontophrynidae
Locations: Brazil
Size: 1.5 – 2.9 inches (40 – 74 mm)

The Boie’s Frog lives in the Atlantic rain forest and other primary and secondary forests of eastern Brazil. They are often found in leaf litter near streams.

When threatened, the Boie’s Frog flattens its body and stiffens its arms out to their side. Researchers believe that this helps the frog better mimic a dead leaf on the ground.

Males call from September to January, end of the rainy season. Eggs are laid in swamps or streams.

The International Union for the Conservation of Nature (IUCN) Red List assesses the Boie’s Frog as Least Concern for Extinction. They have a wide range and a presumed large population. Primary threat to the frog is deforestation to make room for more farms, cattle grazing areas, and human settlements,
