With luck
About 10% of wildlife watchers report a Marbled rubber frog sighting in Namib-Naukluft National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
February and April
In those months about 20% of wildlife watchers report a Marbled rubber frog in Namib-Naukluft National Park on a given day, against under 5% in May to January, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Marbled rubber 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 Namib-Naukluft National Park, in our data
Namib-Naukluft National Park is the only park on Wallace's Line with enough records to rate Marbled rubber frog sightings: about 10% of wildlife watchers there report one on a given day.
Same order: Anura
The closest relatives of the Marbled rubber frog that you can see in Namib-Naukluft National Park (order Anura, Frogs and Toads) are Poynton's River Frog (about 10%) and African Clawed Frog (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Marbled rubber frog is recorded against all the amphibians logged in Namib-Naukluft National Park (6 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.
