Élasmobranches (requins et raies) (sharks and rays) >
Myliobatiformes (Stingrays) >
Dasyatidae (Stingrays) > Urogymninae
Etymology: Pateobatis: Combination of Latin 'pateo' for 'lie open, be exposed' and 'batis' for skate, ray or flatfish; referring to the eclectic nature of members of this group..

Maturity: Lm 70.0 range ? - ? cm
Max length : 130 cm WD mâle / non sexé; (Ref. 11228); 110.8 cm WD (female)
Found inshore, on sandy substrates (Ref. 9840, 75154) to depths of 50m (Ref.58048). Inhabits shallow coastal waters (Ref. 45255). Ovoviviparous (Ref. 50449). Common catch of the demersal tangle net, bottom trawl and, occasionally, longline fisheries. Utilized for its meat, skin (very high value) and cartilage (Ref.58048). Max. Length of female given in Ref. 74367.
Life cycle and mating behavior
Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larves
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): 24.9 - 28.6, mean 27.8 °C (based on 168 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5312 [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).
Niveau trophique (Ref.
69278): 3.5 ±0.5 se; based on size and trophs of closest relatives
Résilience (Ref.
120179): Faible, temps minimum de doublement de population : 4,5 à 14 années (Assuming fecundity<100).
Fishing Vulnerability (Ref.
59153): Very high vulnerability (90 of 100).
Nutrients (Ref.
124155): Calcium = 30.6 [7.4, 139.8] mg/100g; Iron = 0.744 [0.185, 1.949] mg/100g; Protein = 22 [19, 25] %; Omega3 = 0.165 [0.047, 0.480] g/100g; Selenium = 43.1 [11.5, 117.9] μg/100g; VitaminA = 11.1 [4.9, 24.6] μg/100g; Zinc = 1.01 [0.49, 1.82] mg/100g (wet weight);
