(total): 145-184. Silvery in color except for front of head, interorbital area, dorsal part of upper jaw, and tip of lower jaw which are black (Ref. 2713). Dusky blotch usually seen on body at bases of 20-28th dorsal rays (Ref. 2713).
A rare (Ref. 2713), mesopelagic species. Feeds on squid and midwater fishes (Ref. 6392). Swims with head up (Ref. 36731). Eggs and larvae are found frequently near the surface (Ref. 6392).

Estimates based on models
Preferred temperature (Ref. 123201
): 8.9 - 20.5, mean 13.5 °C (based on 543 cells).
Phylogenetic diversity index (Ref. 82804
= 0.5166 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.9 ±0.25 se; based on food items.
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Assuming tmax>10).
Fishing Vulnerability (Ref. 59153
): Very high vulnerability (90 of 100).
