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.

Possible
About 20% of wildlife watchers report a Common River Frog sighting in Johannesburg on a given day, based on 49 verified sightings from GBIF citizen-science data. It is the most-seen of the 6 amphibians we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
February–March and November–December
In those months about 30% of wildlife watchers report a Common River Frog in Johannesburg on a given day, against about 10% in January, May and July–August, the lowest months. Those are among Johannesburg's wettest months, with about 95 mm of rain a month against almost none in July.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Common River Frog sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
2nd of 4
Of the 4 cities where we can rate Common River Frog sightings, Johannesburg ranks 2nd at about 20%. The best odds are in Pretoria (South Africa, about 30%).
GBIF citizen-science records
It is estimated from how often the Common River Frog is recorded against all the amphibians logged in Johannesburg (49 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
