簡単な記述 形態学 | 形態計測学

Grey-brown with large dark blotches (Ref. 26346). Tail very short (Ref. 26346). Mid-dorsal row of stout thorns which extend from nuchal region to first dorsal fin. Thorns close posterior to the pelvic girdle larger than along the tail (Ref. 6902). Upper surface dark mouse gray, dark blue gray or dark brown with small rounded spots. Lower surface white and sooty in variable patterns (Ref. 6902).

生物学     用語集 (例 epibenthic)

Found on the lower continental slope (Ref. 6871), probably most common on deep slopes and at abyssal depths (Ref. 114953). Benthic (Ref. 58426); meso- to bathybenthic, on muddy substrate (Ref. 119696). Adults feed on all kinds of bottom animals (Ref. 3167). Prefer polar temperatures from hatching to maturity and eggs are incubated successfully and regularly in water as cold as 0°C (Ref. 6902). 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 capsule measures 81-125 mm long and 50-80 mm wide (Ref. 41251). Hatching size at 16-18 cm TL (Ref. 114953) (15 cm long in Ref. 119696).

Life cycle and mating behavior 成熟 | 繁殖 | 放精 | | 生産力 | 幼生

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 123201): 0.3 - 8.8, mean 3.3 °C (based on 3242 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5010   [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):  4.3   ±0.5 se; based on diet 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).
