A Green Moray Eel (Gymnothorax funebris) emerges from a pipe at the Oregon Coast Aquarium, in Newport, Oregon, USA. While it may look neon green, the skin of the otherwise brown eel actually secretes a yellow-tinted layer of protective, toxic mucus. Moray eels are the only fish (and the only vertebrates) with mobile pharyngeal jaws, an extraordinary hunting innovation where outer jaws firmly grasp the prey, then separate inner jaws within the throat shoot forward to bite the target and pull it in!
