Morphology | Morphometrics
soft rays: 81 - 98;
Vertebrae: 55 - 58. Rostral spine well developed with vertical basal component which projects dorsally, and a long forward projecting straight component; peritoneum and guts black; narrow weak band of basibranchial teeth; bones thin, weakly developed (Ref. 34024). Branchiostegal rays: 7 (Ref. 36413).
Adults are found on soft bottoms, between 429 and 732 m in depth, while juveniles are encountered at shallower depths (Ref. 9329). Prejuveniles mesopelagic (Ref. 34024). Oviparous, with planktonic larvae and extended pelagic juvenile stage (Ref. 36413). Oval pelagic eggs float in a gelatinous mass (Ref. 205).

Estimates based on models
Preferred temperature (Ref. 115969
): 9.4 - 13.8, mean 11.6 °C (based on 38 cells).
Phylogenetic diversity index (Ref. 82805
= 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00269 (0.00127 - 0.00572), b=3.16 (2.98 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.6 ±0.7 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tmax>3).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (32 of 100) .
