Biara—Rhapiodon vulpinus—(Spix & Agassiz, 1829)
Rhapiodon is widely distributed throughout most of South America's major river basins. Looking like a stretch version of a payara (Hydrolycus spp.), the biara is a ready adversary for anglers, aggressively striking artificial lures often meant for other species. The specimen at right weighed 6 pounds and would have been a world record had we had solid ground to weigh it on. We've seen them even larger, exceeding 8 pounds.
