Maturity: Lm ?  range ? - ? cm
Max length : 12.8 cm SL male/unsexed; (Ref. 87970)

Short description Morphology | Morphometrics

Dorsal spines (total): 3; Dorsal soft rays (total): 13-16; Anal spines: 1; Anal soft rays: 8; Vertebrae: 27 - 28. The species is characterized by the following: large head (more than 40% of SL, specimens of SL ? 100.0 mm); first gill arch with 20-22 rakers; total vertebrae 26-28, 11 abdominal; haemal arch of the first caudal vertebra is without a spur; D III,13-16; P14-15; ventral fin with 7 soft rays; ventral fin starts before the vertical line of the posterior margin of the pectoral fin basement; anal fin starts under the vertical line of the 3-4 ray of the dorsal fin (posterior end); operculum with 4 scales (Ref. 87970).

Biology     Glossary (e.g. epibenthic)

Adults caught below 400-500 meters; juveniles in shallower water (Ref. 51657). Specimens were sampled by open-mouth nets at depth range of 1500-0 m; the minimal sampling depth was 62 m (individuals with SL = 12.7-13.3 mm) (Ref. 87970).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00393 - 0.02664), b=3.04 (2.81 - 3.27), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.0   ±0.2 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  High vulnerability (56 of 100) .
