Moray Eels are a type of fish with dorsal and anal fins fused to the caudal fin, forming a single ribbon along the length of the fish. There are over 800 known species of eels and more than 100 species of moray eel, including zebra morays (Gymnomuraena zebra), snowflake morays (Echidna nebulosa), and tessalata morays (Gymnothorax favagineus). Moray eels are not the vicious, deadly animals that many think they are. Most would rather hide in their burrows than attack a human and there is little evidence that they are venomous. Their body is actually brown but appear green due to a yellow mucus that covers their whole body!
