Green Moray Eel (Gymnothorax funebris)

The Green Moray Eel inhabits the deep, shadowy waters of the western Atlantic Ocean. Green Moray Eels can grow up to 7.2 feet long and weigh approximately 64 lbs.

Despite its name, this species is not green, but its natural color is soft brown with a layer of yellow mucus. When hit by light, this mucus gives the appearance of vibrant green. 

These types of eels periodically open and close their mouths because their gills require a continuous flow of water for breathing. They eat mainly fish, squids, and crabs. Lastly, they hide in dark crevices of coral reefs or rocky underwater terrains during the day and come out at night to hunt.
