The rate of descent during a drift dive depends on the buoyancy of the shark; the higher its buoyancy, the slower its rate of descent. Fat is a major component of lipids, a collection of molecules required for cell health and function, especially energy storage. They also live in the waters off South Africa, New Zealand, Australia and in the Mediterranean Sea.
