生物学     用語集 (例 epibenthic)

Bottom-dwellers that feed on invertebrates and bony fish (Ref. 9908). Depth range given by H. Ishihara (pers.comm. 07/07). 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 5.3-6.7 cm long and 2.7-3.9 cm wide (Ref. 41253, 41298).

Estimates based on models

Preferred temperature (Ref. 115969): 18.4 - 26.8, mean 25.2 (based on 82 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5001   [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):  4.0   ±0.61 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):  Low to moderate vulnerability (27 of 100).
