The Gibba Toad-headed Turtle (Mesoclemmys gibba) is a wide-ranging South American species in the lowlands of the Orinoco and Amazon Basins. A relatively small-bodied species with carapace length rarely exceeding 35 cm, the nocturnal M. gibba inhabits rainforest streams, hardpan pools of shallow water in gallery forests, and Mauritia palm swamps. Diet consists primarily of small invertebrates and mollusks. Owing in part to their foul-smelling defensive musk, they are not used as food by local populations of people.
