Maturity: Lm 37.8, range 28 - 50 cm
Max length : 66.0 cm TL самец/пол неопределен; (Ref. 56527); common length : 44.1 cm TL самец/пол неопределен; (Ref. 56476); наибольший вес (опубликованные данные): 550.00 g (Ref. 56476); наибольший возраст (опубликованны данные): 10 годы (Ref. 56527)
колючие лучи спинного плавника (общее число) : 2; колючие лучи анального плавника: 0. Snout short, blunt, with a broad spinous scute at its tip, its leading edge and most of its underside naked; suborbital shelf very narrow anteriorly; interopercle broadly rounded posteriorly; chin with very short barbel. Scales rather deciduous; body scales with 3 to 10 low, subparallel rows of spinules; gill and gular membranes and interopercle naked. Pyloric caeca short, 5 to 7. Overall color is grayish brown; fins blackish to dusky; oral and gill cavities blackish.
Feeds mainly on pelagic forms (Ref. 1371). Too small for fresh consumption (Ref. 1371).

Estimates based on models
Preferred temperature (Ref.
123201): 2.3 - 3.1, mean 2.4 °C (based on 148 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00200 (0.00118 - 0.00338), b=3.09 (2.94 - 3.24), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic level (Ref.
69278): 3.6 ±0.4 se; based on size and trophs of closest relatives
устойчивость к внешним воздействиям (Ref.
120179): средний (среднего размера), минимальное время удвоения популяции 1.4-4.4 года (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Moderate to high vulnerability (46 of 100).
