About Chalcorana raniceps (Peters, 1871)
Chalcorana raniceps is a species of relatively small frog. Adult males measure 28–34 mm (1.1–1.3 in) in snout–vent length, while adult females measure 33–42 mm (1.3–1.7 in). Most individuals are green in colour, and some have a brown back. They have a long, pointed snout, and adhesive disks on their finger and toe tips. The undersides of the thighs may be reddish. This species resembles Chalcorana megalonesa, but is much smaller in size. Its tadpoles are easily noticeable, with dark markings and red gills against a light brown to yellow background; they are presumed to be poisonous. Chalcorana raniceps lives across a wide variety of lowland primary and secondary rainforest habitats. It breeds in ponds, intermittent streams, and quiet side pools of streams. Males call in small groups from twigs and vegetation that are 0.5–1.5 m above the ground.
