Morphology | Morphometrics
soft rays: 4;
Vertebrae: 18 - 19. Relatively short skull, length 24.2% of SL versus up to at least 26% in other species. Extremely thick and leathery skin, studded with small tubercles over entire body. Principal tubercles of ventral surface of tail very stout but relatively short. Fin-rays without tubercles. Pectoral and pelvic fins both relatively short, broad, the covering skin extremely fleshy, with thick membranes. Cephalic lateral-line counts: subopercular 5; preopercular 2. Tail lateral-line counts 11 (Ref. 40826).
A benthic species found on the continental slope (Ref. 75154).
