Swim Bladder

Real World Example

Imagine you have a backpack that you adjust to help you stay balanced while hiking on steep hills. Just like adjusting the weight in your backpack can help you maintain your position on a slope, a fish uses its swim bladder to maintain its position in the water without floating up or sinking down. In this analogy, the weight in your backpack is like the gas in the swim bladder, allowing you to control your elevation effortlessly, just as the fish controls its depth in the water.
