Sharks are slightly heavier than water, so they naturally tend to sink. Buoyancy or lift is provided in two ways. First, sharks store large quantities of oil in their liver. Because oil is less dense than water, storing this oil decreases the overall density of the shark, and increases its buoyancy. Second, as a shark swims, its pectoral fins provide lift, in much the same way the wings of an airplane does. If a shark stops swimming it will sink, but its stored oil and relatively light skeleton help it to float and decreases the amount of energy that must be expended on swimming.

Why would a shark need to regulate its internal salt concentration?
hi
Why do fish float in fish tanks?
Fish have an gas-filled, internal swim bladder, whose buoyancy they regulate to keep from sinking or rising in the water.
What affect provided by water aerobics helps make the exercise beneficial?
Buoyancy
Why is liver the main organ for sharks buoyancy if it only gives off oil in not so large quantities while stomach can hold and compress air and use them like submarines?
Liver is much larger in sharks as compared to stomach.Liver not only helps in buoyancy but also keeps shark upright. there are other factors which are also involved in buoyancy.
What happens to a great white shark when it stops moving?
Jellyfish lack buoyancy and sink to the bottom of the ocean if they stop moving.
What kind of buoyancy do submarines have when they are resting on the surfce of the ocean?
Positive Buoyancy. When submarine submerges, it initially uses negative buoyancy to submerge, and then levels out to neutral buoyancy.
What does buoyancy help with?
High buoyancy=easy to float
Does freshwater have buoyancy?
Yes, all fluids have buoyancy.
Was buoyancy always called buoyancy?
yes, it is the same.
Could you find a scientific sentence with the word buoyancy?
We are merely testing the buoyancy of several types of ping pong balls.
