seewasser bathydemersal; tiefenbereich 257 - 1537 m (Ref. 27311). Temperate; 55°N - 35°N
North Pacific: Sagami Bay, Japan to the southern Kuril Islands and off Sakhalin, Russia.
Length at first maturity / Size / Gewicht / Alter
Maturity: Lm ?, range 28 - ? cm
Max length : 44.0 cm SL Männchen/unbestimmt; (Ref. 56407); common length : 26.4 cm SL Männchen/unbestimmt; (Ref. 56407); max. veröff. Gewicht: 1.2 kg (Ref. 56527)
Rückenflossenstacheln (insgesamt) : 15 - 16; Rückenflossenweichstrahlen (insgesamt) : 8 - 10; Afterflossenstacheln: 3; Afterflossenweichstrahlen: 5; Wirbelzahl: 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).
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).
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): PD
50 = 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.
Widerstandsfähigkeit (Ref.
120179): niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (tm=10; Fec=69,355).
Fishing Vulnerability (Ref.
