Contains: Lycodontis, Gymnothorax.

The Muraenidae, morays, are powerful-headed marine eels found in tropical and subtropical waters.

Characters (from Böhlke et al. 1999): Small to very large eels (to 375 cm); body elongate, firm, muscular, and compressed; many species robust and powerful, some small species nearly worm-like. Dorsal profile of head above and behind eye raised due to the development of strong head muscles. Eyes well developed. Snout short to elongate, jaws usually equal. Anterior nostril tubular, near tip of snout. Posterior nostril high on head, above or before eye, a simple pore or in a tube. Mouth large, gape usually extending behind posterior margin of eye, lips without fleshy flange. Jaw teeth usually strong, in one or more rows, ranging from sharply pointed and depressible canines or fangs to blunt molars, teeth on vomer (roof of mouth) uniserial, biserial, or in a patch. Gill opening a small round hole or slit at midside. Dorsal and anal fins variously developed, from dorsal fin beginning on head and anal fin immediately behind anus, to both fins restricted to tail tip; dorsal and anal fins continuous with caudal fin around tail tip; pectoral and pelvic fins absent. Scales absent. Lateral-line pores absent on body except for one or two above and before gill opening (tiny dots may be present along lateral line on body, but these are not pores); pores on head almost always limited to four along upper jaw, three near tip of snout, and six on lower jaw; no pores behind eye or in supratemporal commissure.
