Leptodactylus didymus, the Madre de Dios thin-toed frog, is a species of frog in the family Leptodactylidae. It is found in Bolivia, Brazil, and Peru. This terrestrial frog has been seen in primary and secondary rainforests and sometimes urban areas. Scientists have seen it between 0 and 450 meters above sea level.
Scientists have reported the frog in protected places: Tambopata National Reserve, Parque Ambiental Chico Mendes, Reserva Experimental Catuaba, Parque Nacional da Serra do Divisor, and Parque Zoobotânico da Universidade Federal do Acre in Brazil.
This frog deposits its eggs in a nest out of bubbles, a few hundred at a time. The tadpoles have been observed aggregating to survive low-water conditions. The IUCN classifies this frog as least concern of extinction. Wikipedia →

Possible
About 30% of wildlife watchers report a Madre de Dios Thin-toed Frog sighting in Manu National Park on a given day, based on 59 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 9th most-seen of the 67 amphibians we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Madre de Dios Thin-toed Frog is recorded against all the amphibians logged in Manu National Park (59 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.
