A greasy rock cod or greasy grouper (Epinephelus tauvina) on Jena Reef off the coast of Mafia Island. He has mouth open to warn off myself and fellow scuba divers.
They are known for standing their ground when potential predators approach. Instead of fleeing, they remain stationary, maintaining eye-contact and showing their teeth to make themselves look as frightening as possible.
