Cathorops is a genus of fish in the family Ariidae found in Atlantic and Pacific Ocean. These species are found in the eastern and western Central and South America in brackish and freshwater habitats.[1] This genus is a strongly supported clade of this family.[1][2] It consists of a natural group in which the monophyly is well-defined by morphological and molecular evidence and the genus probably includes several unrecognized species from both American coasts.[2][3]
