Short description Identification keys | Morphology | Morphometrics

Snout inflated; eyes much smaller than snout; opercular spine weak or absent; preopercle without spines and posteriorly expanded almost reaching posterior margin of opercle; pseudobranchial filaments 2 (Ref. 34024).

Rare, deep pelagic species (Ref. 34024). Benthopelagic (Ref. 58302). Oviparous, with oval pelagic eggs floating in a gelatinous mass (Ref. 205). Of the 5 female specimens caught, 2 with 0.5 mm eggs. No identifiable stomach contents were found. Specimen collection used non-closing, pelagic fishing gear (bottom trawls) (Ref. 84269). Minimum depth from Ref. 58018.

Estimates based on models

Preferred temperature (Ref. 123201): 0.2 - 3.3, mean 1.9 °C (based on 856 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.6 ±0.6 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (22 of 100).
