How important is the presence of air bladder in pisces
Hi,The presence of bladder helps in maintaining buoyancy in the water.
air bladder provide them a buoyant force thus they doesn`t have to swim constantly to avoid sinking .
If we compare cartilaginous fishes and Bing fishes Cartilaginous fishes don`t have air bladder or swim bladder so they have to swim continuously otherwise they would sink . Incase of bony fishes they have swim bladder or air bladder so they don`t have to swim continuously(Air bladder - buoyancy )
Bony fishes have air bladder to provide them buoyancy othetwise they would sink in water. ....................
HelloGas bladder or air bladder is a gas filled sacpresent in fishes. It helps in maintaining buoyancy. Thus it helps fishes(pisces) to ascend and descend and stay in water current. Good luck and hope you understand.
If Pisces have air bladder they donnot need to swim continuously but in absence of bladder they you have to swim it helps in maintaining buoyancy.
