背面の脊椎 (合計) : 3; 背鰭 (合計) : 106 - 116; 臀鰭: 80. Body extremely elongate, compressed and tapering to a point. Mouth very large with a small dermal process at the tip of each jaw. Pelvic and caudal fins absent. Lateral line originating at the upper margin of the gill cover, running obliquely to behind the tip of the pectoral fins, then parallel to the ventral contour of the body.
