Habitat
This species inhabits shallow coastal waters, estuaries, and lagoons in the southeastern Atlantic and western Indian Ocean, such as off South Africa, Namibia, and Mozambique. They prefer sandy or muddy substrates where they can bury themselves partially. These areas often have brackish water influenced by river outflows.
Diet
The Backwater butterfly ray primarily feeds on benthic invertebrates like crabs, shrimp, and mollusks, which it uncovers by flapping its pectoral fins to stir up sediment. It also consumes small fish occasionally. Feeding typically occurs at night when the ray is more active on the ocean floor.
Behavior
Backwater butterfly rays are generally solitary and benthic, spending most of their time buried in sand or mud to ambush prey. They exhibit nocturnal activity patterns, emerging at night to hunt, and may migrate seasonally to follow warmer waters or food sources. These rays are not highly territorial but can be defensive if disturbed.
Conservation Status
Listed as Data Deficient by IUCN.
