Short description Morphology | Morphometrics

Dorsal spines (total): 15 - 16; Dorsal soft rays (total): 8-10; Anal spines: 3; Anal soft rays: 5; Vertebrae: 27 - 30. Pectoral fin with notch, rays of lower lobe thick; head spine strongly and sharply produced; maxillary extending to middle of eye (Ref. 559). Body yellowish-red, a large black blotch on dorsal fin (Ref. 559).

Biology     Glossary (e.g. epibenthic)

Occurs in places with the steepest downthrow and sharp bends of sea bottom often in the places of the slope surrounded by large depths (the steep bottom relief causes vertical turbulent currents that provide the accumulation of food items) (Ref. 26289). Oviparous (Ref. 205). Eggs are extruded in floating gelatinous masses (Ref. 52092).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Eggs are enclosed in a gelatinous matrix which floats to the sea surface (Ref. 559). Females possess specialized ovarian structures including stalk-like ovigerous lamellae and secretory epithelia (Ref. 32832).

Estimates based on models

Preferred temperature (Ref. 123201): 1.1 - 3.7, mean 2.5 °C (based on 89 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00912 (0.00410 - 0.02027), b=3.09 (2.89 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.40 se; based on food items.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (tm=10; Fec=69,355).
Fishing Vulnerability (Ref. 59153):  High to very high vulnerability (69 of 100).
