The Dourado (Salminus brasiliensis) is a large river fish that lives in central and east-central South America. Despite having Salminus in its name, the dorado is not related to any species of salmon, nor to the saltwater fish also called dorado. The Dourado have large heads, with powerful jaws that are filled with sharp teeth. They reach maturity around 37 centimetres (15 in) long, and are golden colored. The average size of the golden dorado is about 3–10 kilograms (6.6–22 lb). Golden Dorado live in warm freshwater habitats in southern Brazil, Paraguay, Uruguay, Bolivia and northern Argentina.
