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.
The ribbon eel or Bernis eel, is a species of moray eel.
The presumed juveniles and subadults are jet black with a yellow dorsal fin, in adult males the black is replaced by blue, and adult females are entirely yellow or yellow with some blue to the posterior.
