Short description पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स

Moderate size, with a short blunt snout. Disk has rounded corners, few tubercles and spines along midline (Ref. 26938). Well developed fold on the upper surface and lower surface of tail. Yellowish or light brown above. Lower surface whitish or pure white (Ref. 6902).

जीवविज्ञान     शब्द संग्रह (उदाहरणार्थ epibenthic)

Inhabits coastal waters (Ref. 7251). Generally found near shore, to depths of 10 m. Both adults and juveniles frequent estuaries and surf zones (Ref. 27549). Bottom feeder with fish, clams, worms and shrimps. It causes a number of injuries to bathers and waders (Ref. 26938). Ovoviviparous (Ref. 50449). Litters of 2-4 pups; gestation 10-11 months, including a period of embryonic diapause (Ref. 114953).

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

Estimates based on models

Preferred temperature (Ref. 123201): 23.1 - 28.1, mean 27.1 °C (based on 760 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5039   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00646 (0.00265 - 0.01571), b=3.06 (2.86 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.7   ±0.2 se; based on diet studies.
लौटाव (Ref. 120179):  निम्न, न्यूनतम जनसंख्या दुगनी होने का समय 4.5 - 14 वर्ष। (Assuming fecundity<100).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100).
Nutrients (Ref. 124155):  Calcium = 26.4 [3.6, 122.6] mg/100g; Iron = 0.744 [0.197, 2.068] mg/100g; Protein = 23.9 [21.1, 26.5] %; Omega3 = 0.23 [0.06, 0.69] g/100g; Selenium = 12.5 [3.8, 37.8] μg/100g; VitaminA = 9.03 [3.46, 23.49] μg/100g; Zinc = 0.738 [0.357, 1.351] mg/100g (wet weight);
