Hydrostatic organ of bony fishes

Vedclass · Answer

(A) The air bladder,also known as the swim bladder,is a gas-filled sac found in many bony fishes $(Osteichthyes)$.It functions as a hydrostatic organ that regulates buoyancy,allowing the fish to maintain its depth in the water without expending energy.In contrast,cartilaginous fishes $(Chondrichthyes)$ lack an air bladder,which forces them to swim continuously to prevent sinking.
