Description

The Cunning moray is a moray (Muraenidae) from reef and rocky water of the Indo-West Pacific. The species grows to about 30 cm and has a slender, eel-like, scaleless body without pectoral fins and a mouth with sharp teeth; the skin is often finely spotted or marbled. As a nocturnal predator it shelters by day with only its head out of a crevice and hunts small fish and crustaceans at night. It does not attack people, but can bite fiercely when threatened or handled.
