The Amazonian poison frog (Ranitomeya ventrimaculata), known in French as dendrobate à ventre tacheté, is a species of poison dart frog. It is native to South America, where it can be found in Brazil, southeastern Colombia, Ecuador, French Guiana, and Peru.
R. ventrimaculata secretes poison through glands in the skin which protect it from fungi and bacteria as well as from predators, which are also warned to stay clear by the aposematic coloration. It is therefore often included among the poison dart frogs, although its toxin is comparatively weak. R. ventrimaculatus produces its poison by ingestion of a species of mite.
The frog is active during the day. It grows to a size of about 20 millimetres (0.79 in), with males smaller than females. Its base color is black, and it has yellow lines or dots on the back, whereas the belly has bluish or grayish color with interspersed black patches (hence the name "ventrimaculatus"); the color of the belly continues into a netlike pattern on the legs.
R. ventrimaculata reach adulthood at an age of six months. The females attach four to eight eggs to leaves beneath the water level, where they are... Wikipedia →

Possible
About 20% of wildlife watchers report a Reticulated Poison Frog sighting in Yasuní National Park on a given day, based on 25 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 15th most-seen of the 49 amphibians we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
February
In that month about 50% of wildlife watchers report a Reticulated Poison Frog in Yasuní National Park on a given day, against under 5% in March–June, August and October–November, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Reticulated Poison Frog sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Among the best
Of the 2 parks where we can rate Reticulated Poison Frog sightings, Yasuní National Park ranks 2nd at about 20%, level with the leaders once rounded. The best odds are in Amacayacu National Natural Park (Colombia, about 20%).
GBIF citizen-science records
It is estimated from how often the Reticulated Poison Frog is recorded against all the amphibians logged in Yasuní National Park (25 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.
