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; javaensis: Named for its type locality and regional occurrence, off the coast of Java, Indonesia.

生態学
海 底生の. Tropical
Eastern Indian Ocean: Indonesia.
Length at first maturity / サイズ / 重さ / 年齢
Maturity: Lm ? range ? - 18 cm
Max length : 21.2 cm WD オス/雌雄の選別がない; (Ref. 114953); 23.4 cm WD (female)
Apparently benthic on soft bottoms near coast (Ref. 114953); inshore coastal habitats near mangroves, close to heavily human populated areas, thus making it accessible to fishers. Males mature at 17-18 cm WD while females at 18 cm WD. Size at birth 5-9 cm WD (Ref. 130662). Caught by trammel nets (Ref. 114953).
