Genus: Mesoclemmys

Mesoclemmys is a genus of South American freshwater turtles belonging to the family Chelidae. These turtles are known for their distinctive side-necked retracting mechanism, meaning they fold their heads sideways under their shells rather than pulling them straight back. Mesoclemmys species are semi-aquatic, often found in slow-moving rivers, swamps, and flooded forests. They have a broad diet, feeding on aquatic invertebrates, small fish, and plant matter. Adapted to diverse habitats, some species can tolerate seasonal droughts by burrowing into mud. Their cryptic coloration helps them blend into their environment, aiding in predator avoidance.
