Short description पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स

A moderate-sized devilray with a short head bearing short head fins; dorsal fin white-tipped, and pectoral fins with swept-back tips and a prominent double bend to the front margins; upper disc sparsely covered with small, blunt denticles and tail shorter than disc, with no spine (Ref. 5578). Dark blue to black above; white below, with silvery pectoral fin tips (Ref. 5578). No caudal fin (Ref. 5578).

Occurs in coastal and oceanic waters, but more common near the coast (Ref. 9256). Found singly or in small groups (Ref. 12951). Feeds mainly on planktonic crustaceans (Ref. 12951); mostly small shrimp-like animals (Ref.58048). Ovoviviparous (Ref. 50449). Caught occasionally in the tuna gillnet and in harpoon fisheries. Utilized for its gill filter plates (high value), meat, cartilage and skin (Ref.58048). Can leap out of the water.

Life cycle and mating behavior Maturities | पुनरुत्पत्ति | Spawnings | Egg(s) | Fecundities | लार्वा

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). With one large offspring per gestation period. Size at birth 65-85 cm (Ref. 6871).

Estimates based on models

Preferred temperature (Ref. 123201): 21.6 - 29.1, mean 27.8 °C (based on 2652 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.30 se; based on food items.

लौटाव (Ref. 120179): बहुत नीचे, न्यूनतम जनसंख्या दुगनी समय अवलागत 14 महीने। (Fec=1).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (85 of 100).

Price category (Ref. 80766): Medium.

Nutrients (Ref. 124155): Calcium = 7.99 [1.05, 135.60] mg/100g; Iron = 0.83 [0.08, 10.24] mg/100g; Protein = 20.6 [15.3, 25.9] %; Omega3 = 0.157 [0.047, 0.501] g/100g; Selenium = 22.8 [4.7, 120.5] μg/100g; VitaminA = 4.56 [0.35, 57.84] μg/100g; Zinc = 0.483 [0.030, 5.484] mg/100g (wet weight);
