Pleurodema thaul, the Chilean four-eyed frog is a species of frog in the family Leptodactylidae. It is found in Argentina and Chile. Individuals vary in size between 3 and 5 cm in snout-vent length. The female frogs are larger than the males. The skin of the dorsum can be yellow, green, or dark green in color. The frogs have symmetrical brown spots. The belly is white in color.
They feed on arthropods such as flies and spiders. In Chile they are found from the Antofagasta region to the Aysén Region, while in Argentina they live in areas close to the Andes in the provinces of Neuquén, Rio Negro, and Chubut.
Reproduction occurs almost throughout the year. This frog can reproduce in almost any body of water. The tadpoles are gray with dark spots. The IUCN classifies this frog as least concern of extinction. In some parts of the range, some of the frogs may be in some danger from fire, water pollution from farms and other industry, land conversion, and drought.

With luck
About 10% of wildlife watchers report a Chilean Four-eyed Frog sighting in Nahuel Huapi 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 30%, and over a week to about 60%, if each day is a fresh chance.
March–April and October–November
In those months about 20% of wildlife watchers report a Chilean Four-eyed Frog in Nahuel Huapi National Park on a given day, against under 5% in January and May–September, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Chilean Four-eyed Frog sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is seen both by day and at night.
Only Nahuel Huapi National Park, in our data
Nahuel Huapi National Park is the only park on Wallace's Line with enough records to rate Chilean Four-eyed Frog sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Chilean Four-eyed Frog is recorded against all the amphibians logged in Nahuel Huapi 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.
