Épines dorsales (Total): 2. Small ventral light organ, lacking a dermal window; ventral surface of head and lower jaw covered with small spinulated scales; dorsal surface of head with scales except for small naked anterior lateral areas; snout short, 33.7% HL, armed with terminal and lateral scutes; orbit large 37.9% HL; scales armed with rows of low, parallel spinules, with spinule rows overlapping hind margin of scale; 10 gill rakers on inner side of first arch; margin of upper lip dark brown (Ref. 26363).
Probably inhabits areas not suitable for sampling with a bottom trawl (Ref. 26363).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00575 (0.00195 - 0.01700), b=3.08 (2.83 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Niveau trophique (Ref.
69278): 3.5 ±0.5 se; based on size and trophs of closest relatives
Résilience (Ref.
120179): Faible, temps minimum de doublement de population : 4,5 à 14 années (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
