Nightfall in the misted lowland forests of Costa Rica, Panama, and northern Columbia awakens a brown frog with characteristic blue thighs. The Panama cross-banded treefrog (Similisca sila) hides among the dense overhanging vegetation on forest floors. The moisture of mist and droplets of water are not enough for the little frog; it stays close to slow-moving stream banks and shallow rocky pools where its tadpoles can be found. It is not afraid of the dark or of heights. It can venture higher in the forest or even to more open landscapes if it so desires. The Panama cross-banded treefrog can live in secondary forest complete with dense vegetation. It has been found ranging from sea level to 500 meters above sea level. Leer más.
