Porcupinefish are fish of the family Diodontidae, (order Tetraodontiformes), also commonly called blowfish (and, sometimes, "balloonfish" or "globefish").
They are sometimes confused with pufferfish. Porcupinefish are closely related to pufferfishes but porcupinefish have spines on their body.
Porcupinefish 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. Some species are poisonous, having a tetrodotoxin in their skin and/or intestines. As a result, porcupinefish have few predators: adults are rarely eaten except by sharks and orcas, though juveniles are also preyed on by tuna and dolphins.
