(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.. More on authors: Jordan & Seale.

Length at first maturity / Size / Peso / Age
Maturity: Lm 115.4, range 120 - ? cm
Max length : 183 cm TL maschio/sesso non determinato; (Ref. 40637); peso massimo pubblicato: 18.5 kg (Ref. 40637)
Uniformly tan to brownish pink dorsally. Inhabits lagoon and seaward sand flats from the intertidal to at least 200 m. Occurs in large aggregations (Ref. 37816).
Occurs in aggregations over soft bottoms of the inner continental shelf, often near coral reefs (Ref. 9840). Ovoviviparous (Ref. 50449). Size at birth at about 55 cm WD (Ref. 6871). Feeds on fishes, crustaceans and molluscs (Ref. 89972). Common catch of the demersal tangle net, bottom trawl and, to a lesser extend, longline fisheries. Utilized for its meat, skin (high value) and cartilage (Ref.58048). By-catch of prawn trawlers (Ref. 6871).
Life cycle and mating behavior
Maturità | Riproduzione | Deposizione | Uova | Fecundity | Larve
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). Size at birth ~ 55 cm WD (Ref.58048).
