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!

The gummy shark or Sweet William is a fish that is usually found on the continental shelves and frequently fished along the Australian shores.
Scientifically speaking, the class that this particular species of shark belongs to is called Chondrichthyes. Largely, they can be classified as fish.
While there are no studies that tell us the exact number of these fish that there are in the world, their conservation status suggests that they are not endangered and are flourishing!
The Mustelus antarcticus species is most commonly found on continental shelves. Since these are bottom-dwelling fishes, it is not often that you will spot a school when swimming along the shoreline.
The preferred habitat for gummy sharks is around Southern Australia. This species does not exhibit any major migratory tendencies. However, some males and females do travel short distances in the later years of their lives.
Despite what you might think of when you hear the word 'shark' (Mustelus antarcticus) is actually a rather meek variety of sharks. They tend to flee from larger species and from humans as well. They usually prefer to live with their own family, when not undertaking long travels.
The average lifespan of a gummy shark fish or Australian smoothhound is up to 16 years, if not disturbed by any calamities or man-made hazards. They spend all of their lives in the depths of the ocean when not bred in fisheries.
The Mustelus antarcticus is an ovoviviparous shark, which means that the female's eggs, on fertilization, remain inside her body during the entire gestation period. The female then gives birth to the hatched pups. The average litter size is about 14. However, the female fish may carry as few as one and as many as 57 pups in one gestational cycle. The gestation period in this species lasts from 10 - 12 months.
If you're looking for examples of other ovoviviparous animals, you can look up seahorses, great white sharks, nurse sharks, and tiger sharks!
The conservation status of Mustelus antarcticus or Flake Shark is said to be of Least Concern by the IUCN. Though they are frequently fished along the shores of Australia, they are not endangered.
Mustelus antarcticus or Australian smooth hound or Sweet William is a species of rather slim-looking sharks. They are pale gray or silver in color and have a white-colored belly. Occasionally, you might spot one that has dark brown or white spots on their body. They have flat teeth that are arranged in the shape of a pavement: this allows them to crush the shells of their prey easily. Their teeth and shape are very different than those of the other varieties of sharks that we are usually scared of, and in turn, make them pose no threat to humans.
Their fins are usually of the same length and are pointed, which might let you confuse them with the Killer Sharks or a Giant gummy shark.

With their slim bodies and cute teeth, The gummy sharks are a rather cute species to catch a glimpse of!
You will find it interesting that gummy sharks or Australian smoothhounds usually arch their bodies in certain ways in order to communicate with their school! They also have the ability to sense vibrations, and hence, can navigate through the sea with their mates.
Gummy sharks' length can be as much as 69 in (175 cm). Females of this shark species usually grow to be larger than males.
There are no conclusive studies about the exact speed at which a school of gummy sharks can swim in the sea, but sharks are usually known to have an approximate speed of 12 mph (19.3 kph)!
The average weight of the Mustelus antarcticus shark ranges from 55-59 lb (24-25 kg), which is not too heavy for the fishermen to catch if they so wish to!
Males and females of gummy sharks have no names designated to them, so one would usually refer to them as the male gummy shark and the female gummy shark.
The baby gummy sharks, like most other young fishes, are called pups.
The diet of this friendly species of sharks comprises mostly of mollusks and crabs, which they find at the smooth bottoms of the sea in which they dwell. They also occasionally feed on small fishes such as cuttlefish and rays (that are not a part of their school). Given their rather flat teeth, they steer clear of consuming large fish.
A school of gummy sharks is of no danger to humans because of two reasons. They are bottom-dwellers, which keeps them away from the humans that might think of taking a small dip in the sea, and their small size and flat teeth cannot bite that hard or cause any harm to human bodies. They are also bred in fisheries and sold as 'flake' for consumption.
While their small size might give you the impression that they can be kept as pets, gummy sharks can not easily be domesticated because their habitat is not easy to mimic. Additionally, their diet would also make them very high maintenance for any common household.
Gummy sharks are bred in many fisheries around the world to be sold in markets as pets and food.
They are also an easy catch if you happen to know how to fish!
Gummy sharks are popular within Australia - particularly in the fish and chips industry. They are commonly fished for, caught, and sold due to their boneless fillets. They have a mildly sweet taste which pairs well with salted or spicy chips and a fizzy drink!
Yes, gummy sharks have teeth, but unlike the other kinds of sharks, their teeth are blunt and rounded. Such a shape makes it easy for them to prey on crabs and mussels by crushing their shells!
