Maturity: Lm ?  range ? - ? cm
Holotype taken from a depth of 1,000 m (Ref. 26282). Oviparous (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205). Depth range assumed from two records (1000 and 2000 m) (RF).
Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205).

Estimates based on models
Preferred temperature (Ref.
123201): 1.8 - 3.8, mean 2.4 °C (based on 142 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00513 (0.00253 - 0.01042), b=3.12 (2.95 - 3.29), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 4.0 ±0.7 se; based on size and trophs of closest relatives
Daya lenting (Ref.
120179): Rendah, Waktu penggandaan populasi minimum 4.5 - 14 tahun (Fec assumed to be <100).
Fishing Vulnerability (Ref.
59153): High to very high vulnerability (66 of 100).
Nutrients (Ref.
124155): Calcium = 5.07 [1.04, 28.48] mg/100g; Iron = 0.262 [0.063, 0.885] mg/100g; Protein = 15.5 [12.9, 18.0] %; Omega3 = 0.531 [0.170, 2.131] g/100g; Selenium = 17.6 [4.9, 59.1] μg/100g; VitaminA = 10.7 [2.1, 56.9] μg/100g; Zinc = 0.333 [0.158, 0.649] mg/100g (wet weight);
