Petropedetes martiensseni (Nieden, 1911)
This is a large frog usually found near rocky streams. The dorsum is light tan or brown with irregular darker blotches, and usually with a rosy tinge to the limbs. The dorsal surface is granular in texture with a few scattered bumps and ridges. A fold of skin stretches from the eye to the base of the arm over the tympanum. The tympanum is visible and is smaller than the eye. Toe and finger tips are expanded into heart-shaped disks. Fingers lack webbing, and toes are webbed only slightly at the base. Males in breeding condition have thick arms (Text from Harper et al., 2010).
Petropedetes yakusini is similar in appearance, but the ranges of the two species do not overlap (Text from Harper et al., 2010).
Males are approximately 74 mm in snout-vent length; females are 50-67 mm (Harper et al., 2010).
This species is found in rocky forest streams within undisturbed forestat elevations between 600 and 1800 m (Harper et al., 2010).
Eggs are laid on wet rocks near streams or seepage areas. Tadpoles have wide mouths that allow them to cling to and graze on the surface of rocks. Metamorphs are around 12 mm in length. Outside of the breeding season adults are found on the forest floor in holes and among rocks (Text from Harper et al., 2010).
