With luck
About 10% of wildlife watchers report a Sharp-nosed ridged frog sighting in iSimangaliso Wetland Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 19th most-seen of the 22 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.
January
In that month about 20% of wildlife watchers report a Sharp-nosed ridged frog in iSimangaliso Wetland Park on a given day, against under 5% in March–April, June–August, October and December, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Sharp-nosed ridged frog sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Only iSimangaliso Wetland Park, in our data
iSimangaliso Wetland Park is the only park on Wallace's Line with enough records to rate Sharp-nosed ridged frog sightings: about 10% of wildlife watchers there report one on a given day.
Same genus: Ptychadena
The closest relatives of the Sharp-nosed ridged frog that you can see in iSimangaliso Wetland Park (genus Ptychadena, Ridged Frogs) are Anchieta's Ridged Frog (about 10%) and Nile Ridged Frog (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Sharp-nosed ridged frog is recorded against all the amphibians logged in iSimangaliso Wetland Park (12 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.
