Himantura australis (Australian Whipray)
https://fishesofaustralia.net.au/home/genus/671
From Fishes of Australia: A yellowish to pale brownish whipray densely covered in dark-brown spots, speckles or reticulations, a white underside with a broad dark margin sometimes containing dark spots, and the tail densely spotted or reticulated near the barb, and blackish or marbled behind the barb. Newborn pups are densely covered in close-spaced dark spots that coalesce to form a reticulated or honeycomb pattern in larger juveniles.
In Australia, the Australian Whipray was previously known as Himantura uarnak, a species that is widespread in the Indo-Pacific, but not found in Australia.
