Size and Habitat Size- The grow to about 130 cm long. Habitat-This species is found in mangrove-fringed rivers and estuaries, and offshore to at least 28 m depth, but more commonly in shallow inshore waters. As well as occurring in marine and estuarine waters, it is known to move up rivers to beyond the tidal limit.

Distribution Where in the world they are found- The species occurs in the the Gulf of Carpentaria and along the east coast of Australia south to Sydney. Estuary stingrays were once common in south-east Queensland. However, the rapid urban growth along the Gold Coast, Moreton Bay and Sunshine Coast coastline has placed enormous pressure on their habitat.

When did they evolve?

Habits Feeding The species is reported to be a major predator of shellfish, including farmed oysters. Individuals move over mudflats with the incoming tide to feed, and in Moreton Bay, southern Queensland they have been found to feed on soldier crabs. Breeding Some rays lay eggs while others reproduce giving birth to live young that develop in the womb without a placenta. Fertilization is always internal. Rays have a long gestation period and produces relatively few young compared to other fish. The growth of ray populations, therefore, is slow.
