生物学     用語集 (例 epibenthic)

Found on deeper continental slopes and probably abyssal plains, mainly deeper than 1,400 m (Ref. 3167). Oviparous (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205). It is caught as by-catch in low numbers by deep trawl fisheries (Ref. 117245).

Estimates based on models

Preferred temperature (Ref. 115969): 3.4 - 6.6, mean 5.4 (based on 13 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00302 (0.00141 - 0.00645), b=3.24 (3.07 - 3.41), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
栄養段階 (Ref. 69278):  3.3   ±0.45 se; based on food items.
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):  High vulnerability (56 of 100).
