Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 2. Lips of upper and lower jaws very darkly pigmented; a series of about five (indistinct posteriorly) brownish black saddle marks on the dorsal surface of the body, the first broad, starting before the first dorsal fin origin, the third smaller and paler than the others when viewed dorsally; ventral light organ small, lacking a dermal window; ventral surface of head and lower jaw almost entirely covered with small, heavily spinulated scales; snout moderately long 45.4-51.7% HL; mouth large, with upper jaw 26.0-33.3% HL; suborbital ridge not supported by continuous bone; buccal cavity black; fins pale dusky except for anal fin which has black pigmentation distally along anterior four-fifths (Ref. 26363).
Appears to form small schools (Ref. 26363).

Estimates based on models
Preferred temperature (Ref.
123201): 5.7 - 8.2, mean 6.6 °C (based on 14 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [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.

Trophic level (Ref.
69278): 3.7 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Moderate to high vulnerability (53 of 100).
