The Marañón slider is a freshwater turtle from Brazil. It lives in rivers and lakes in the northeast of the country, spends a lot of time in the water, and comes ashore to bask and lay eggs.
The Marañón slider differs from other sliders by the absence of a red spot behind the eyes and a special yellow pattern. It is important for nature because it eats aquatic plants and small animals and serves as prey for predators. The species is threatened due to habitat destruction.
