Short description

Disc width equal to disc length; tail shorter than body; ventral surface of disc entirely white (Ref. 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).
