Gladiator treefrog (Hyla rosenbergi) on a leaf. This frog is found in or near small pools at low and middle elevations. Gladiator frogs are so called because males have a sharp bony spine on each hand, which is used as a weapon in fights between males over females and nests. Photographed in Toachi Pilaton valley, Pichincha, Ecuador.
