Body extremely elongate and strongly compressed, ribbon-like, tapering to a point. Dorsal profile of head evenly convex; mouth large with a dermal process at tip of each jaw; lower hind margin of gill cover convex; eye very large situated laterally, its diameter 5 or 6 times in head length; 2 or 3 fangs in upper and 2 fangs in lower jaw, a single series of sharp compressed lateral teeth in both jaws. A single, long-based, dorsal fin with V spines and 126 to 144 soft rays; anal fin represented by I minute first spine and I scale-like second spine, situated below 47th to 50th soft dorsal-fin ray, reduced to minute spinules buried in skin thereafter; pectoral fins short, not reaching lateral line; pelvic fins present but reduced to scale-like processes; caudal fin absent, posterior part of body tapering to a point. Lateral line running almost straight mid-lateral, or slightly nearer ventral than dorsal contour. In fresh specimens, body silvery white becoming silvery grey with dark cloud-like patches after death; each jaw, dorsal and anal-fin bases sooty.
