A Swim Bladder


A Swim Bladder is an internal, gas-filled bladder that most bony fish use to regulate their buoyancy.


By adjusting the gas pressure inside the bladder, a fish can become neutrally buoyant, meaning that is neither rises or sinks.


Associated Terms: Gas Bladder, Fish Maw, Air Bladder
