Maturity: Lm ? range ? - ? cm
Max length : 36.0 cm SL male/unsexed; (Ref. 559)
Head large, about as wide as deep, usually longer than 1/4 total length of body. Orbit oval, moderate in size. Sensory canals on head spacious. Mouth small, entirely inferior. Teeth conical. Scales nearly hexangular, thin and rather deciduous; spinules weak, slender, in 6-14 divergent rows. A large, naked area present dorsally behind anterolateral margin of snout. Nasal fossa largely naked. Luminous organ long, superficial blackish streak about as long as head exclusive of snout; anterior photophore fossa-like, but scaled (Ref. 54421).

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=0.00251 (0.00128 - 0.00492), b=3.19 (3.03 - 3.35), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.6 ±0.5 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.).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (34 of 100).
