Short description Morphology | Morphometrics

Dorsal spines (total): 2. Pelvic rays usually 11. Underside of head mostly scaled, but a median-ventral naked swath below snout tip; pores of sensory system on head relatively small. Scales densely covered with narrowly to broadly lanceolate spinules in somewhat convergent rows; 7.0-8.5 rows below second dorsal origin; 34-40 lateral line scales over distance equal to predorsal length. First dorsal fin dusky to black. Anterior dermal window of light organ between insertions of pelvic fins. Barbel 1.8-2.0 into orbit diameter, 15-20% of HL; preoral length 23-28%; orb.-preop. 38-44%.

Estimates of some properties based on models

Preferred temperature (Ref. 115969): 5.7 - 7.1, mean 6.7 (based on 14 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00219 (0.00097 - 0.00495), b=3.17 (2.98 - 3.36), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.3   ±0.1 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (46 of 100) .
