balloonfish

Animals have different defense mechanisms to help protect themselves from predators. The balloonfish is no exception. When an enemy attacks, this fish responds by puffing itself out and filling its stomach with air or water. The balloonfish expands its body to look larger in order to intimidate predators. In addition to their puffed-up status, their body is also covered in spines that make them look quite menacing.
