Actinopterygii (ray-finned fishes) > Scorpaeniformes
(Scorpionfishes and flatheads) > Sebastidae
(Rockfishes, rockcods and thornyheads) > Sebastolobinae
Etymology: Sebastolobus: Greek, sebastes = august, venerable + Greek, lobos = lobe (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; bathydemersal; depth range 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 / Weight / Age
Maturity: Lm ?, range 28 - ? cm
Max length : 44.0 cm SL male/unsexed; (Ref. 56407); common length : 26.4 cm SL male/unsexed; (Ref. 56407); max. published weight: 1.2 kg (Ref. 56527)
(total): 15 - 16;
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).
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).
