Of the 13 species of snooks, seven live in the tropical and subtropical western Atlantic from North Carolina to Porto Alegre and six more in the eastern Pacific from Baja California to Peru and the Galapagos Islands . They occur in the coastal sea and in brackish water , some species also in fresh water in river underflows.
