Correct Answer: Cartilaginous fish
Solution : The correct answer is Cartilaginous fish.
A swim bladder, also known as an air bladder, is a gas-filled organ that aids in the control of buoyancy in fish. It is located in the fish's dorsal cavity and is filled with gas produced by the swim bladder gland. Cartilaginous fish lack swim bladders because they do not require them to regulate their buoyancy.
