Centropomus

Commonly known as snooks or róbalos, the Centropomus species are native to tropical and subtropical waters of the western Atlantic and eastern Pacific Oceans.

Occurring in a variety of habitats ranging from coral reefs to estuaries and mangrove swamps, the snooks are carnivorous, feeding primarily on crustaceans and other fishes.

The generic name Centropomus derives from the Greek κέντρον (centre, in this sense "sting") and πώμα (cover, plug, operculum).

Róbalo or snook are world-renowned game fish of the family Centropomidae and genus Centropomus that are much sought after by fly-fishing enthusiasts and sportfishing charters.

No evidence has been found of the individual species crossing from the Atlantic to the Pacific or vice versa through the Panama Canal.

All snook species are capable of inhabiting both fresh and saltwater and are known to seasonally occupy Gatun Lake, which forms a water bridge connecting the Atlantic and Pacific Oceans as an integral part of the Panama Canal.

The four large species are immediately recognizable by their more streamlined appearance given by their longer, narrower body shape.
