OCEANA on SAND TIGER SHARKS
Excerpt: The sand tiger shark lives worldwide near the seafloor in surf zones, shallow bays and coral and rocky reefs. They are a large species, growing to a maximum length of 10.5 feet (3.2 m) and weight of 350 pounds (159 kg). The sand tiger shark is the only shark that is known to maintain neutral buoyancy by gulping air at the water’s surface and holding it in its stomach. This allows the sand tiger shark to hover motionless in the water.
