生物学     用語集 (例 epibenthic)

Deep-sea species (Ref. 8630). Small individuals feed on crabs and annelids, while larger ones prey on fish and cephalopods (Ref. 27640). 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 10.9-11.3 cm long and 6.5-6.7 cm wide (Ref. 41249, 41253).

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). Eggs have horn-like projections on the shell (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 123201): 0.3 - 4.1, mean 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=0.00427 (0.00269 - 0.00676), b=3.09 (2.96 - 3.22), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
栄養段階 (Ref. 69278):  4.1   ±0.72 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):  Very high vulnerability (76 of 100).
