Description

The giant moray is the largest moray (Muraenidae) of the Indo-Pacific. The species grows to about 3 metres and has a heavy, elongate, snake-shaped, scaleless body that in adults is dark and mottled with black spots. As a nocturnal top reef predator it hides by day in caves and crevices and seizes fish and octopus at night. Large specimens are among the most important ciguatera carriers and must not be eaten; it also bites fiercely when disturbed. Caution is advised.
