Etymology: Brevitrygon: Name from Latin 'brevis' meaning short and 'trygṓn' meaning stingray, referring 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.

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).
