Short description Identification keys | Morphology | Morphometrics
Dorsal spines (total): 0; Dorsal soft rays (total): 99 - 113; Anal spines: 0; Anal 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).
Body shape (shape guide): elongated; Cross section: oval.
Body shape (shape guide): elongated; Cross section: oval.
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
|
Phylogenetic diversity index (Ref. 82804) |
PD50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high]. |
| Bayesian length-weight | a=0.00275 (0.00131 - 0.00577), 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 |
| Generation time | 1.8 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies. |
|
Resilience (Ref. 120179) |
Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tmax>3). |
|
Fishing Vulnerability (Ref. 59153) |
Low vulnerability (24 of 100). 🛈 |
