The wide stingaree (Urolophus expansus) in the Urolophidae family is endemic to Australia, and found off southwestern Australia (think from Port Lincoln all the way to Perth). Found in sandy substrates in about 200–300 m (660–980 ft) deep around continental shelves. A flattened diamond-shaped disc, a pointed snout, and lacks dorsal fins. A grayish green color, they have blue lines beside and behind their eyes. They can get up to 52 cm (20 in) in length.
Their diet consists of isopods and polychaete worms. The momma wide stingarees supply their unborn pups with histotroph ("uterine milk"). These animals are caught as bycatch in commercial trawl fisheries operating in the Great Australian Bight. The International Union for Conservation of Nature (IUCN) has listed it under Least Concern (LC).
