生物学     用語集 (例 epibenthic)

Benthic in shallow waters over sandy bottoms (Ref. 9262). Ovoviviparous (Ref. 50449). Produces litters of 1-6 pups. Females mature at ca. 48 cm TL, males at ca. 51 cm TL; born at 19 cm TL (Ref. 114953).

Life cycle and mating behavior Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 幼生

Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. 50449).

Estimates based on models

Preferred temperature (Ref. 115969): 26.6 - 29.1, mean 28.3 (based on 115 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5039   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00182 (0.00117 - 0.00283), b=3.12 (2.99 - 3.25), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
栄養段階 (Ref. 69278):  3.6   ±0.5 se; based on size and trophs of closest relatives
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):  High to very high vulnerability (71 of 100).
