D'Orbigny's slider (Trachemys dorbigni) also commonly known as the black-bellied slider, and in Brazil as tartaruga-tigre or tartaruga-tigre-d'água (which mean "tiger turtle" and "water tiger turtle" in Portuguese), is a species of water turtle in the family Emydidae. The species is found in southern Brazil, northeastern Argentina, and Uruguay.
The specific name, dorbigni, is in honor of French naturalist Alcide d'Orbigny. Trachemys dorbigni is usually found in bodies of water such as lakes, marshes, streams and rivers. It has a preference for waters with low or moderate currents, soft bottoms and abundant aquatic vegetation.
The gender of Trachemys dorbigni can be determined by the form of the plastron, which after a few years of life, shows differences between male and female. The males has a penis that is located in the tail and becomes apparent only during the mating season when it is inserted into the female's cloaca. D'Orbigny's slider has a life span of between 30 and 100 years in captivity.
Hatchlings weigh 11 grams (0.39 oz) with a 3.5 cm (1.4 in) carapace. The average growth rate is about 3 cm (1.2 in) per year in the wild,... Wikipedia →

With luck
About 10% of wildlife watchers report a Black-bellied Slider sighting in Tijuca National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 19th most-seen of the 21 reptiles we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
March, June, August and October–November
In those months about 10% of wildlife watchers report a Black-bellied Slider in Tijuca National Park on a given day, against under 5% in April–May, July, September and December–February, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Black-bellied Slider sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 3
Of the 3 parks where we can rate Black-bellied Slider sightings, Tijuca National Park ranks 2nd at about 10%. The best odds are in El Palmar National Park (Argentina, about 50%).
GBIF citizen-science records
It is estimated from how often the Black-bellied Slider is recorded against all the reptiles logged in Tijuca 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.
