A free-swimming ribbon eel captivated divers off the coast of Mauritius earlier this month. Ribbon eels fascinate divers with their bright colors and snake-like appearance. Also known as Rhinomuraena quaesita, they change color throughout their lives. Juveniles are black with a yellow dorsal fin, while adult males develop a vibrant blue body with yellow highlights and females are mostly yellow.
