生物学     用語集 (例 epibenthic)

Inhabit inshore waters (Ref. 3167). Depth range to 170 m (Ref. 04426), and from 333-343 m in the eastern Ionian Sea (Ref. 56504). Feed on all kinds of benthic animals (Ref. 3167). 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 4.5 cm long and 3.0 cm wide (Ref. 41304). Minimum depth range (Ref. 117283).

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). Spawning peak in summer to early autumn with 30 to more than 100 egg-cases per year depending on the size of the female (Ref. 3167). Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 115969): 13.3 - 15.7, mean 14.3 °C (based on 100 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00269 (0.00164 - 0.00442), b=3.23 (3.09 - 3.37), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
栄養段階 (Ref. 69278):  3.8   ±0.6 se; based on diet studies.
Generation time: 2.4 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
