|Borneo eared frog|
Rhacophorus otilophus Boulenger, 1893
Polypedates otilophus (also known as the file-eared tree frog, Borneo eared frog, or bony-headed flying frog) is a species of frog in the family Rhacophoridae. It is endemic to Borneo where it is widespread and found in Brunei, Indonesia, and Malaysia, typically in the lowlands but sometimes as high as 1,100 m (3,600 ft) above sea level. This species has prominent, sharp ridges behind the eye, above the ear, referred to in its names.
Males measure up to 80 mm (3.1 in) and females up to 100 mm (3.9 in) in snout–vent length. The body is robust and dorsally lemon yellow in color, with many thin, black stripes; also the thighs have many black bars. The tympanum is conspicuous, with a serrated bony crest above it (the "ear"). Fingertips are expanded into large discs; those on the toes are smaller. The fingers have only rudimentary webbing whereas the toes are moderately webbed.
Habitat and conservation
Polypedates otilophus typically occurs in secondary habitats, at the edges of primary forest, and also in villages. They are most easily spotted at suitable breeding ponds where adults perch on vegetation 1–4 m above the ground. It is not considered a threatened species by the IUCN.
