Happy St. Patrick’s Day from this green moray eel in Florida Keys National Marine Sanctuary! 

Green moray eels are actually brownish, but they don green in celebration of holidays – or, rather, to protect themselves from parasites and disease. That is, these eels secrete a yellowish mucus that covers their skin, giving them a greenish tinge.
