Vertebrae: 202 - 206. This species is distinguished by the following characters: elongate and unpatterned body and fins which is uniformly greyish brown; anus located just before mid-body, preanal length 2.0 in TL; head length 11.3 in TL; depth at gill opening 27.8 in TL; uniserial teeth, few, long and needle-like; mean vertebral formula 7-89-206 (Ref. 106142).
The 73.6 cm TL female was gravid and distended with 1.0-1.2 millimeter eggs (Ref. 106142).

= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00048 (0.00026 - 0.00087), b=3.28 (3.13 - 3.43), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 4.0 ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
