Etymology: Brevitrygon: Derived from brevis (Latin), meaning short and trygṓn (Greek τρυγών), meaning stingray, in allusion to the short, semi-rigid tails of these stingrays;  walga: Name is presumably a variant spelling of wolga, from Wolga Tenkée, a local name for this or a related stingray from the Ganges Delta of India..

Biologie     Verklarende woordenlijst (bv. epibenthic)

Demersal on insular and continental shelves, and occasionally found in coastal embayments (Ref. 58048); primarily in shallow water from near the shore in estuaries to nearby fishing grounds in bays (Ref. 130662). Ovoviviparous (Ref. 50449). Caught in large quantities as by-catch of bottom trawl and trammel net fisheries. Utilized for its meat, but of limited value due to its very small size (Ref.58048).

Levenscyclus en paargedrag Maturities | Voortplanting | Spawnings | Egg(s) | Fecundities | Larven

Ovoviviparous (Ref. 205), with histotrophy. Gives birth to litters of 1-2 pups; no reproductive synchronicity. Born at 8-10 cm WD (Ref.58048). Distinct pairing with embrace (Ref. 205).
