生物学     用語集 (例 epibenthic)

Occurs in coastal waters, continental shelf and upper slope (Ref. 26346). Usually found in deeper waters to 200 m (Ref. 9258). Mainly feeds on benthic decapods and bony fishes (Ref. 114953). Oviparous (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205). Males reaches maturity at ca. 150 cm TL. This species is said to be long lived and slow growing (Ref. 114953).

Estimates based on models

Preferred temperature (Ref. 123201): 6.4 - 12.9, mean 8.2 °C (based on 173 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00224 (0.00133 - 0.00376), b=3.24 (3.10 - 3.38), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
栄養段階 (Ref. 69278):  4.1   ±0.6 se; based on size and trophs of closest relatives
Generation time: 11.6 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
回復力 (Ref. 120179):  低い, ４．５年～１４年の倍増期間の最小個体群 (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (80 of 100).
価格帯 (Ref. 80766):   Medium.
