Their dorsa are uniform pale green, olive, red-brown or lichenose, with green or olive spots on a black background. Several species have pale upper labial and lateral stripes. Some fingers or toes have moderate webbing. DescriptionDuellmanohyla are small or moderately small frogs. The dorsum is uniformly pale green, olive, reddish brown, or lichenose, and bears green or olive spots on a black background. The iris is bright red, orange, or yellow. The fingers and toes are moderately webbed.[2]EcologyDuellmanohyla breed in fast-flowing mountain streams. To adapt to this habitat, the frogs have a moderate degree of webbing on the forefeet and on some digits of the hind-feet. Egg-laying has not been observed in any species in the genus, and it is thought that the females may deposit their eggs on the foliage above the water of swift-flowing mountain streams, the tadpoles then falling into the stream when they hatch. The tadpoles have dangling oral discs by which they can attach themselves to the substrate.[2]SpeciesThe genus contains eight species:[1]
