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; imbricata: Name fro Latin 'imbricata' meaning overlapping each other, referring to the secondary denticle band, which is very narrow over the branchial region and abdomen in this species.

Disc width equal to disc length; tail shorter than body; ventral surface of disc entirely white (Ref. 12693).
體盤寬度等於體盤長度; 尾部短於身體; 體盤的腹面表面完全白色.(參考文獻 12693)
Found in inshore coastal waters (Ref. 30573). Typically found in estuarine habitats, but also reported from the Great Lake. The single record from the Great Lake may in fact refer to Dasyatis laosensis. Young and adults feed on benthic invertebrates (Ref. 12693). Ovoviviparous (Ref. 124). Feeds on bottom-living invertebrates (Ref. 68964). May grow to a maximum of 140 cm disc length in the sea (Ref. 43081). Juveniles may be present in mangroves (Ref. 43081). Examined adult males 17.1 cm DW (32.0 cm TL) - 20.5 cm DW (39.8 cm TL); females 13.8 cm DW (25.6 cm TL) - 20.4 cm DW (39.6 cm TL); early juveniles (USNM 222564, immature male 12.0 cm DW and female 8.8 cm DW) have lost umbilical scars. Reported maximum disc width 30.0 cm (Ref. 11312) was found excessive (Ref. 130662).
發現於近海沿岸水域了。 (參考文獻 30573) 典型地發現於河口的棲息地了, 也記錄自五大湖。 單一記錄從五大湖可能事實上指的是 Dasyatis laosensis. 幼魚與成魚吃底棲的無脊椎動物。 (參考文獻 12693) 卵胎生的.(參考文獻 124) 在海洋中對 140 的極大可以生長公分體盤長度。 (參考文獻 43081) 稚魚可能是出現在紅樹林.(參考文獻 43081)

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).印度-西太平洋: 紅海與模里西斯到印尼。
