Dendropsophus triangulum (Faivovich, Haddad, Garcia, Frost, Campbell, and Wheeler, 2005)
The triangle tree frog (Dendropsophus triangulum) is a frog that lives in Ecuador, Peru and Brazil. Scientists have seen it between 34 and 387 meters above sea level.[3][1]
This frog is brown in color with yellow or white stripes. At least a few frogs have a spot on their necks in the shape of a triangle. The adult male frog is 28.6 to 34.4 mm long from nose to rear end and the adult female frog is 37.5 to 41.9 mm long. The female frog lays eggs on leaves so that the tadpoles fall into the water.[1]
