生物学特性     字汇 (例如 epibenthic)

Inhabit deep slope waters (Ref. 3167), probably most common on the mid-slope (Ref. 114953). Feed on all kinds of bottom animals (Ref. 3167), mainly invertebrates and small fishes (Ref. 114953). Size possibly up to 250 cm TL (Ref. 114953). Oviparous. Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205). Eggs are oblong capsules with stiff pointed horns at the corners deposited in sandy or muddy flats (Ref. 205). Egg capsules are 18.2-26.0 cm long and 9.2-11.3 cm wide (Ref. 41251, 41309). Sizes of maturity and hatching unknown (Ref. 114953).

栖息于深的斜坡水域。 (参考文献 3167) 捕食各种的底部动物。 (参考文献 3167) 卵生的。 明显的成对出现。 幼鱼可能倾向跟随大的个体, 例如他们的母亲.(参考文献 205) 卵为长方形鞘囊具有僵硬的触角沈积在沙滩或泥滩的角落.(参考文献 205) 卵鞘是 18.2-26.0 公分长与 9.2-11.3 公分宽的.(参考文献 41251,41309)

Estimates based on models

Preferred temperature (参考文献 123201): 2.1 - 10.8, mean 7.1 °C (based on 138 cells).
Phylogenetic diversity index (参考文献 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00282 (0.00131 - 0.00604), b=3.25 (3.08 - 3.42), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
营养阶层 (参考文献 69278):  3.5   ±0.37 se; based on food items.
回复力 (参考文献 120179):  低的, 最小族群倍增时间4.5 - 14 年 (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100). 🛈
