The green moray eel (Gymnothorax funebris) is a large, solitary reef predator found in the Atlantic Ocean and Caribbean Sea, often seen peering from holes in the reef with its gaping mouth and vivid green skin. The green hue comes from a yellow mucus coating over its naturally dark body, helping protect it from parasites and infections. Growing up to 2.5 meters long, this moray is one of the largest in the western hemisphere and a regular highlight for divers and snorkelers throughout the region. Though they look fearsome, green morays are generally docile, posing no threat unless provoked.
