The green moray (Gymnothorax funebris) is a moray eel of the family Muraenidae, found in the western Atlantic Ocean from Long Island, New York, Bermuda, and the northern Gulf of Mexico to Brazil, at depths down to 40 metres (130 ft).

Though it is not considered endangered, the species is particularly under-studied and estimated to be undercounted by up to 400% in single-pass visual surveys.

Its green colour comes from a protective layer of mucus secreted by its specialized goblet cells much like other species of moray.

Underneath this mucus layer, the green moray eel is a darker color as can be seen in preserved specimens.
