Leptodactylus marmoratus, commonly known as the marbled tropical bullfrog, is a common species of frog in the family Leptodactylidae. It is commonly found under and on the surface of dead leaf litter and dead branches. This bullfrog has a distinctive call that it sounds from dusk to dawn. It is nocturnal. It feeds on isopods, ants, and insect larvae that are found in abundance in their habitats.
It is endemic to southern Brazil in the states of Minas Gerais, Rio de Janeiro, São Paulo, and Paraná. Scientists have seen it between 0 and 1,200 m (0 and 3,937 ft) meters above sea level. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, and rural gardens. It is threatened by habitat loss caused by agriculture and human intrusion but is considered to be of least concern. Wikipedia →

Rare
Under 5% of wildlife watchers report a Marbled Tropical Bullfrog sighting in São Paulo on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 8th most-seen of the 13 amphibians we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
February
In that month about 10% of wildlife watchers report a Marbled Tropical Bullfrog in São Paulo on a given day, against under 5% in March to January, the lowest months. That is one of São Paulo's wettest months, with about 180 mm of rain against 35 mm in August.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Marbled Tropical Bullfrog 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 São Paulo, in our data
São Paulo is the only city on Wallace's Line with enough records to rate Marbled Tropical Bullfrog sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Marbled Tropical Bullfrog is recorded against all the amphibians logged in São Paulo (9 verified sightings), 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.
