Pale in color but with black tips on pelvic fins (Ref. 6612). Very small ventral fins and low vertebral count. Cephalic lateral line scale counts: preopercular 2-4; subopercular 4-6; dorsolateral branch of subopercular 4-6; supraorbital 7-10. Disk subglobose, with ventral surface flat; trapezoidal in outline. Illicial cavity very large. Lower jaw projecting relative to upper jaw. Dorsal surface of rostrum broad, flat; anterior margin slightly concave; no enlarged median spine. Gill rakers formed as triangular plates with tiny teeth at distal angle. Fins weak, ventral fins extremely reduced in size. Tail relatively short and slender. Esca with rounded, paired, ventral lobes and a broad, relatively low dorsal lobe. Skin translucent, flabby. Entire body covered with small tubercles with slender spines giving it s semi velvety appearance (Ref. 40825). |
