There is no such thing as an "air blubbler" in a shark.

No. Sharks are fish, they breathe water through their gills.
Sharks do indeed float in seawater. They have an air bladder which assists them in their nautical excursions.
Sand sharks, also known as sand tigers shark or ragged toothed sharks, are lamniform sharks of the family Odontaspididae (or sometimes - but incorrectly - referred to as Carchariidae). They are found on both sides of the Atlantic coast, but most notably in the Western Indian Ocean and in the Gulf of Maine. There are four species in two genera. Sand sharks are the only known shark to surface for gulps of air. They store the air in their stomachs which allows them to float motionless in the water as they hunt for prey.
No, they do not need bubblers. They do, however, really enjoy having some live plants in the tank with them.

They do, they just use gills to extract the air in water.
