Definition
Balloonfish are a type of pufferfish, closely related to porcupinefish, known for their ability to inflate into a balloon-like shape.🐡 They possess smaller spines than porcupinefish, which become erect when inflated. These fish inhabit tropical and subtropical waters. They inflate with water or air to deter predators. Think of them as a pufferfish with a slightly smoother, balloon-like appearance.
