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.

首次成熟时的长度 / 大小 / 重量 / 年龄
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).
丰富的在沿海地区。 也冒险进入大的沿岸海湾。 卵胎生的.(参考文献 50449)

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).西太平洋: 泰國到印尼東南部。 記錄來自印度了, 但是由於與 Himantura imbricata 混淆, 在印度洋的它的西方分布是不清楚的。
