Description

The Red-tailed payara is a large predatory characin (Cynodontidae) from fresh water of the Amazon and Orinoco basins in South America. The species grows to about 59 cm and has a streamlined, silvery body and a lower jaw with two enormous, dagger-like fangs that fit into holes in the upper skull. The fins and tail have a conspicuous red-orange tinge. As a fast open-water hunter it darts at smaller fish in rapids, impaling them with the fangs. It is a valued sport fish. The fish poses no danger to swimmers.
