Dried Puffer Fish. Porcupine fish have the ability to inflate their body by swallowing water (or air) and become round like a ball. This increase in size (almost double vertically) reduces the range of potential predators to those with much bigger mouths. A second defense mechanism is provided by the sharp spines, which radiate outwards when the fish is inflated.
