Disc width equal to disc length; tail shorter than body; ventral surface of disc entirely white (Ref. 12693).
Body shape (shape guide): other.
Body shape (shape guide): other.
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).

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).
