Description

The argus moray is a moray (Muraenidae) from the eastern Pacific, off Central and South America. The species grows to about 120 cm and has an elongate, snake-shaped, scaleless body densely covered with numerous pale, dark-rimmed eyespots (hence 'argus'). As a nocturnal reef predator it hides by day in crevices of rocky reefs, with only the head showing, and seizes fish and crushes octopus at night. It bites fiercely when disturbed. Handle with care.
