Open encyclopedia reference
Astyanax bagual is a species of freshwater ray-finned fish belonging to the family Acestrorhamphidae, the American characins. This fish is known only from the Taquari-Antas river basin in southern Brazil. It is unusual in the genus Astyanax because mature male specimens display bony hooks on the rays of all fins; in opposition, most others have them on the anal, pelvic, or pectoral fins - sometimes on more than one of these, but very rarely on all fins. It can further be told apart from various congeners by way of dentition and some aspects of coloration, including the presence of two humeral spots instead of one (which is more common). Though it lives in a somewhat restricted area, A. bagual is thought to be more widespread than has been recorded. As well as this, it bears physiological similarities to several congeners known to be resilient and adaptable. As such, despite not being evaluated officially by the IUCN, A. bagual is generally considered a species of least concern.
