Dendropsophus triangulum, commonly known as the triangle treefrog, is a species of frog in the family Hylidae. It is native to the Amazon Basin of Brazil, Ecuador, and Peru, but may also be present in Colombia. Dendropsophus triangulum is known from Brazil (Acre, Amazonas, and Pará), Ecuador (Orellana and Sucumbíos), and Peru (Cusco and Loreto) at altitudes of 37–387 m (121–1,270 ft) above sea level. It can be found in primary and secondary tropical rainforests, around temporary ponds in clearings near forests, and in aquaculture ponds.
Dendropsophus triangulum reproduces in temporary water bodies, with tadpoles developing in water after hatching from eggs laid on leaves. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Variable Clown Tree Frog is recorded against all the amphibians logged in Yasuní National Park (5 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.
