D'Orbigny's slider or black-bellied slider (Trachemys dorbigni) is a species of water turtle in the family Emydidae found in southern Brazil, northeastern Argentina, and Uruguay. One subspecies (in addition to the nominate subspecies) is distinguished, Trachemys dorbigni brasiliensis.
The form of the plastron determines its gender. Only terrestrial species, after a few years of life, show differences between male and female. Males have a penis that is inserted into the tail. It becomes apparent only during the mating season when it is inserted into the female's cloaca.
Babies are born weighing 11 grams (0.39 oz) with a 3.5 centimetres (1.4 in) carapace. When the males reach sexual maturity (after 2 years), they acquire a dark color while the females keep the same green after maturity (at 5 years).
Females produce an average of 9 eggs per buried nest. Incubation ranges from 2 to 4 months. The sex of baby turtles is determined by the temperature of the sand during incubation: lower temperatures increase the number of females.
These omnivorous turtles can eat almost anything: shrimps, vegetables, fruit, carrion, small fishes, snails, etc.
This species can be owned only with specific documentation. The purchase invoice must contain the popular and scientific name, and designate the number of animals. Also required is a certificate of origin, invoice number and the number of commercial breeding of wildlife as recorded in the Brazilian IBAMA. In Uruguay turtles can only be owned with specific documentation and as they are a protected species commercialization is forbidden.
