Gummy sharks (Mustelus antarcticus) are a species that find their native land in Southern Australia. They are characterized by their blunt teeth, which is quite unlike the sharp teeth that most sharks are known to have.

Due to the bluntness of their teeth and the fact that they dwell at the bottom of the sea, they usually feed on mussels, crabs, clams, and smaller fish, whose shells they can easily crush.

They are quite slimly built and have dorsal fins that are both roughly of the same size. These pale gray are silver-colored fishes are commonly known in Australia as Sweet William and Australian Smooth Hound, and their flesh is sold in the market at Flake.

They are quite popularly caught and eaten all around Australia due to the sweet flesh and the boneless fillet that they yield. They are widely available all along the shores, and their meek nature assures that no harm is posed to humans.

The fishing industry of Australia is largely benefitted from these slender, friendly sharks. The next time you get Fish and Chips from the local takeaway, notice that it is probably a gummy shark that you are being served!
