Aubria masako

Adult males measure 63–79 mm (2.5–3.1 in) in snout–vent length; females are larger The maximum length is about 100 mm (3.9 in). The tympanum is large and distinct, and the supratympanic fold is present. The finger and toe tips are rounded but not enlarged. The fingers have only some dermal fringes, whereas the toes are moderately webbed. The dorsum is brown and has dark speckles. A white or off-white vertebral line may be present. The underside is speckled white over a brown background, turning almost entirely white in older individuals (the exception being from the throat). Both sexes have conspicuous yellow-brown femoral glands close to the knee.[3][4]

Aubria masako occurs in swamps or along small streams in lowland forests, gallery forests, and degraded secondary habitats (farm bush) in the forest zone. Breeding takes places in standing water, in pools, swamps, and marshes.[1] It is nocturnal, burrowing in mud when inactive. The diet consists of—somewhat unusually for an amphibian—of fish (e.g., Epiplatys), but also of arthropods and other amphibians, including younger conspecifics.[3][4]

Although it is considered an adaptable species, in parts of its range Aubria masako is only known from pristine habitats. Nevertheless, this species is not considered to face any significant threats. It is presumably to be found in several protected areas.[1]
