Himantura australis

This species can be distinguished from several characteristics, such as weakly rhomboidal-shaped disc, short preorbital snout, narrowly rounded lateral apices, yellow-pale brown body color, white-colored underside, and fully covered in scattered dark brown speckles or reticulations.^[2][3] The maximum size of the female specimen is 140 cm disc width.^[2]

This species distribution range encompasses Northern Territory, Western Australia, and Queensland in Australia, and both Indonesian Papua and the sovereign Papua New Guinea.^[2][1] It inhabits the shallow habitats and ranges from the surface to a depth of around 45 m.^[1] It is often accidentally caught by trawlers and fishers in Australian region, but it might be a target and used as delicacy by the locals of Papua New Guinea.^[1]
