Taille / Poids / Âge
Maturity: Lm ? range ? - ? cm
Max length : 26.3 cm SL mâle / non sexé; (Ref. 31384)
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.

50 = 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.
