Yellow-mouth Moray Eel in the Red Sea (Eilat, Israel)

“This moray eel was resting among some hard coral and was mesmerized by my dive lights, making it a very cooperative subject. The moray eel rhythmically opens and closes its mouth to move water through its gills and facilitate respiration, giving it the appearance of being aggressive and making for a dramatic portrait.” -- Nature's Best photographer, Steven Kovacs
