Gymnothorax is a genus of fish in the family Muraenidae found in Atlantic, Indian and Pacific Ocean. With more than 120 species, it the most speciose genus of moray eels.

Smith (2012) noted that Gymnothorax as currently recognized is polyphyletic, but cautioned that comparative studies are needed before action is taken to resurrect generic synonyms of Gymnothorax.[2]


There are currently 128 recognized species in this genus:[3]
