Tetraodontiformes

 

an order of bony fishes. The bones of the upper jaw are firmly joined together or fused. The teeth form a strong beak. The body, which varies greatly in shape, ranges in length from 4 cm (Triacanthadidae) to 2.5 m or more (ocean sunfish). The scales have been converted into spines or scutes. Some species, including the porcupinefish and the puffer, have a special abdominal outgrowth filled with water or air that inflates the entire body when attacked by a predator.

The order Tetraodontiformes has four suborders: Balistoidei, Ostraciontoidei, Tetrodontoidei, and Moloidei. There are 11 families, with about 100 species, distributed in all oceans in tropical and subtropical coastal and open waters; only a few species occur in fresh waters. The fishes feed on bottom invertebrates, specifically, reef-forming coral polyps, pelagic crustaceans, squid, and various fishes. Their diet occasionally includes algae. Many species of the family Balistidae and the suborder Tetrodon-toidei are toxic, because tetrodotoxin is present in the skin, peritoneum, liver, and gonads. However, the meat of these fishes is highly valued in many countries.
