The skin of the dorsum is light brown in color with darker brown spots and bars on the legs. There is lighter color above the mouth. The belly is also lighter in color.
Its natural habitats are subtropical or tropical dry forests, subtropical or tropical moist lowland forests, subtropical or tropical seasonally wet or flooded lowland grassland, rivers, intermittent rivers, shrub-dominated wetlands, swamps, freshwater marshes, intermittent freshwater marshes, arable land, pastureland, plantations, rural gardens, urban areas, heavily degraded former forest, ponds, aquaculture ponds, sewage treatment areas, irrigated land, seasonally flooded agricultural land, and canals and ditches.

With luck
About 10% of wildlife watchers report a Sharp-nosed Jungle Frog sighting in Manu National Park on a given day, based on 18 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 30th most-seen of the 67 amphibians we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
January and February
In those months about 30% of wildlife watchers report a Sharp-nosed Jungle Frog in Manu National Park on a given day, against under 5% in April–May, July–September and December, the lowest months. Those are among Manu National Park's wettest months, with about 260 mm of rain a month against 60 mm in August.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Sharp-nosed Jungle Frog sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
2nd of 2
Of the 2 parks where we can rate Sharp-nosed Jungle Frog sightings, Manu National Park ranks 2nd at about 10%. The best odds are in Tambopata National Reserve (Peru, about 40%).
Same genus: Leptodactylus
The closest relatives of the Sharp-nosed Jungle Frog that you can see in Manu National Park (genus Leptodactylus, Neotropical Grass Frogs) are Peru white-lipped frog (about 30%), Madre de Dios Thin-toed Frog (about 30%) and Loreto White-lipped Frog (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Sharp-nosed Jungle Frog is recorded against all the amphibians logged in Manu National Park (18 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.
