|Porcupinefishes are small, stout fishes whose bodies are covered with short spines or long pointed quills. Like the pufferfishes they can inflate their bodies through the intake of air or water, using an organ in the throat called a buccal pump. The inflation and the spines tend to make them undesirable to predators. Their teeth, one upper and one lower tooth, form a parrot-like beak used for crushing hard-shelled invertebrates. Porcupinefishes are not considered a good food fish, but they are sometimes collected and sold as curios in souvenir shops.
