À propos

Ossubtus xinguense, the Alderschanabel Pacu, is a freshwater fish of the family Serrasalmidae, the pacus and piranhas—a diverse South American group that includes herbivorous, omnivorous, and predatory species. Adults reach approximately 25 cm in length and up to 0.38 kg in weight. The genus Ossubtus is a monotypic group, meaning this is the sole species in its genus, which itself suggests notable morphological distinctiveness within the family. Like most pacus, O. xinguense is presumed to be primarily herbivorous or omnivorous, with robust molariform teeth adapted to processing hard food items such as seeds and plant material in flooded forest environments. The species name xinguense references the Xingu River in Brazil, a major tributary of the Amazon renowned for its extraordinary fish diversity and endemism. Details of habitat and range for this species remain limited in the ichthyological literature. Its conservation status has not been formally assessed. Serrasalmid fishes are economically and ecologically important throughout the Amazon and Orinoco basins.
