About the Common River Frog

Amietia delalandii, also known as the Delalande's river frog, the Drakensberg frog, Drakensberg river frog, or Sani Pass frog, is a species of southern African river frog in the family Pyxicephalidae. It is found in Lesotho, South Africa, Mozambique, Malawi, Zimbabwe, and possibly Zambia. It is the sister species to A. vertebralis.

River frogs all have streamlined bodies with pointed noses and live close to water. They have well-developed hind legs and when disturbed rapidly leap into the water, where they may remain submerged for long periods. Males reach a snout–urostyle length 58 mm (2.3 in) and females 83 mm (3.3 in). The toes are partially webbed. The colouration is variable but typically the dorsum ranges from dull brown to luminous green with a pale brown background with orange flecks, and is covered by small dark brown blotches. About half of individuals have a prominent pale vertebral stripe. The tympanum is more than half the diameter of its eye and is dark with pale flecks. The gular area is usually marbled, with the marbling extending to the chest; otherwise, the underside is unmarked and uniformly pale.
