脊つい: 130. Diagnosis: A large Dasyatis species most closely related to the much smaller Dasyatis margaritella and to the extremely flat D. garouaensis (Ref. 26277). Pearl spines always present and very large; denticles on dorsal surface of disc smooth, restricted to middle portion (Ref. 26277).

生物学     用語集 (例 epibenthic)

Dasyatis margarita is a coastal marine species, entering lagoons, shallow bays and estuaries (Ref. 3497, 81259). Feeds on shrimps, crabs, bivalves and annelids (Ref. 28587). Ovoviviparous (Ref. 50449).

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). Distinct pairing with embrace (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 123201): 23 - 28, mean 26.5 °C (based on 76 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5156   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00832 (0.00366 - 0.01891), b=3.10 (2.90 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
栄養段階 (Ref. 69278):  3.4   ±0.50 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 (Assuming fecundity<100).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100).
価格帯 (Ref. 80766):   Low.
Nutrients (Ref. 124155):  Calcium = 34.7 [8.3, 159.9] mg/100g; Iron = 0.765 [0.192, 2.007] mg/100g; Protein = 21.9 [19.0, 24.9] %; Omega3 = 0.174 [0.049, 0.512] g/100g; Selenium = 41.1 [11.0, 113.3] μg/100g; VitaminA = 13.3 [5.9, 29.3] μg/100g; Zinc = 1.1 [0.5, 2.0] mg/100g (wet weight);
