A large species of moray eel.

Don't confuse him with the yellow moray as they live in wholly different ocean; this one (Gymnothorax funebris) live in the Atlantic ocean while other (Gymnothorax prasinus) live in Pacific Ocean.

Availability of cleanerfish also differ for these morays, eels in Atlantic have neon blue cleaner gobies, while Pacific's have bluestreak cleaner wrasses.

Geographic range:
West Atlantic Ocean
