Ross Allen's tree frog

Ross Allen's tree frog ("Dendropsophus rossalleni") is a frog that lives in Colombia, Peru and Brazil. Scientists have seen it as high as 200 meters above sea level but not higher.
The adult male frog is 19.0 to 22.3 mm long from nose to rear end and the adult female frog is 28.2 to 28.7 mm long. This frog lives in forests.
The male frogs sit near leaves by the surface of the water and sing for the females to come lay their eggs.
