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.

With luck
About 10% of wildlife watchers report a Common River Frog sighting in Kruger National Park on a given day, based on 38 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 12th most-seen of the 28 amphibians we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
April to January
In those months about 10% of wildlife watchers report a Common River Frog in Kruger National Park on a given day, against under 5% in February and March, the lowest months.
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.
Only Kruger National Park, in our data
Kruger National Park is the only park on Wallace's Line with enough records to rate Common River Frog sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Pyxicephalidae
The closest relatives of the Common River Frog that you can see in Kruger National Park (family Pyxicephalidae, African Box-headed Frogs) are Edible bullfrog (about 10%) and Marbled sand frog (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common River Frog is recorded against all the amphibians logged in Kruger National Park (38 verified sightings from 2019 to 2026), 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.
