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 →

Possible
About 20% of wildlife watchers report a Black-bellied Slider sighting in Curitiba on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 4th most-seen of the 7 reptiles 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
In that month about 30% of wildlife watchers report a Black-bellied Slider in Curitiba on a given day, against under 5% in March, May and November, the lowest months. That is one of Curitiba's wettest months, with about 220 mm of rain against 75 mm in August.
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 6
Of the 6 cities where we can rate Black-bellied Slider sightings, Curitiba ranks 2nd at about 20%. The best odds are in Porto Alegre (Brazil, about 30%).
GBIF citizen-science records
It is estimated from how often the Black-bellied Slider is recorded against all the reptiles logged in Curitiba (15 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.
