Appearance
editThe adult male frog measures 14.9–17.9 mm in snout-vent length and the adult female frog 15.9–19.0 mm. This frog can differ considerably in both color and morphology. The snout can be round or pointed. Frogs from the Quebrada Docordó area tend to have brown to tan dorsal coloration and frogs from Playa de Oro tend to have gray-brown. The flanks are black in color with an orange stripe, and axillary flash coloration. A bronze-white stripe goes over each shoulder. There is a dark brown stripe on each leg. The legs are transparent orange in color, showing the orange muscle underneath. There is a dark brown spot behind each side of the mouth. The ventrum is white or gray in color.[3]
Habitat
editThis frog lives in lowland rainforests, near streams. People have seen this frog between 100 and 250 meters above sea level. This frog is diurnal.[1]
Reproduction
editThe female frog lays eggs on the ground. After the eggs hatch, the male frog carries the tadpoles to streams, as many as six at a time.[1]
Threats
editThe IUCN classifies this frog as endangered because of its small range and the ongoing alterations to which that range is subject: subsistence logging, mining, and the cultivation of illegal crops.[1]
