Petropedetes perreti

The specific name perreti honours Jean-Luc Perret, a Swiss herpetologist who has specialized in African amphibians.[3][4][6]

Males measure 29–43 mm (1.1–1.7 in) and females 32–49 mm (1.3–1.9 in) in snout–vent length; it is a medium-sized member of its genus. The body is slender. The tympanum is distinct and nearly as large as the eye in males but distinctly smaller in females. The canthus rostralis is distinct but slightly rounded. The dorsum is brownish or greenish marbled with black parts, or more or less uniformly dark, and speckled with white minuscule spots. The hands are unwebbed whereas the feet are fully webbed.[3]

Petropedetes perreti is a forest species that occurs along mountain streams at elevations of 1,200–1,700 m (3,900–5,600 ft) above sea level, or even higher. Adults have been found adhering with their bellies and limbs to stones in strong currents, sitting on stones amidst the river or some meters away from water, and on leaves of plants on the river sides. The egg clutches are deposited on rocks within the splash zone of rapids and waterfalls. The male appears to defend its clutch. The tadpoles can feed in the splash zone and only move to the water when disturbed.[3]

It is threatened by habitat loss caused by agriculture, logging, and human settlements.[1]
