How important is the presence of air bladder in Pisces?
Air bladder is a gas filled sac found in fishes. It is of great importance as it helps in maintaining buoyancy and helps them to ascend or descend and stay still in the water current. It is importance but there are organisms like Chondrichthyes which do not possess air bladder. Thus, the presence of the air bladder is not necessary in Pisces.
