See text Petropedetes is a genus of frogs in the family Petropedetidae, found in sub-saharan tropical Africa.

[6] Perett (1966) has denoted the osteological characteristics as robust and straight clavicles; a hardly bifurcated omosternum; and T-shaped terminal phalanges.

The West African specie Petropedetes natator are identical with other genus members on the basis of toes and fingertips, and the presence of femoral glands in males.

However, they differ by the presence of morphological features such as external voice sacs, mandibular fangs, a ridge on the tongue and conformation of the rheophilous tadpole, from the Central African species.

[6] P yakusini males also share anatomical features such as enlarged arms and spines on throat, with the Central African species.

They inhabit large rocks crossed by small streams and gather on humid rocky surfaces near torrent water during breeding season.

They settle in riverine vegetation or algae-covered stones 10-20 cm above ground level, occurring in syntopy with P. euskircheni.

These have been observed in primary forests, Clutches are glued to submerged rocks, while tadpoles are located in stagnant parts of rivers beneath small rapids.
