Краткое описание
определительные ключи | морфология | морфометрия
позвонки: 160. This elongate species is distinguished by the following characters: tail 1.8-2.0, head 16-17, and body depth 71 in total length; preopercular pores 3 and pores in supratemporal canal 5; teeth are conical, uniserial on jaws and vomer, with 2-3 vomerine teeth; colouration, when preserved body is mostly pale with a fine brown sparse speckling on body and tail; MVF 70-160, total vertebrae 160 (Ref. 101270).
Specimens caught using a benthic dredge. One paratype with the tail missing is assumed to be approximately 33 cm TL by extrapolation (Ref. 101270).

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref.

Trophic level (Ref.
69278): 3.8 ±0.6 se; based on size and trophs of closest relatives
устойчивость к внешним воздействиям (Ref.
120179): высокий, минимальное время удвоения популяции до 15 месяцев (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
