Real bone of a special purpose type of fish, including the trigger fish (trigger fishes), puffer fish (puffers), box puffer (trunkfishes) and ocean sun fish (sunfishes) and so on. Gray trigger fish (Balistes capriscus) is a representative type Tetraodontiformes purpose.

Puffer shaped head (tetraodontiformes) Osteichthyes of a project, there are four sub-orders, 11 families, more than 320 species of 92 genera, 11 families and 52 genera of Chinese-made 106 kinds. Temporal Ru not forked bone connected to the wing ear bones. No ribs, parietal bone, nasal and suborbital. Maxilla and premaxilla often connected or healing. Conical teeth, doors or healing a beak-like tooth dental plate. Gill openings small, lateral. Scaly body was ossification, bone plates, small spines or nudity. Dorsal 1 or 2; ventral thorax or sub-chest position, or disappear. Belt heal or disappear. Bladder and with or without airbags. Most marine fish, only a few live in fresh water, or in a certain season into the rivers. Mainly in the Pacific, Indian and Atlantic warm tropical and subtropical waters, a few in temperate or boreal. Most of coastal demersal fish, a few pelagic fish. Mostly crustaceans, shellfish, young fish for food, the teeth of which puffer Branch, barbed puffer subjects such as healing a dental plate, able to chew hard food. Its special structure of the esophagus, enlarged ventral ventral and forward into the airbag, air or water when Yudi swallow, so the chest and abdomen swollen into a ball, floating in the water. Many species in the spring and summer to move offshore, coastal waters to spawn, a few species of freshwater rivers into reproduction, fecundity number more than 10 million to 100,000, and roll it up to 300 million puffer for brood fish the amount of the highest bidder. The many species of poisonous fish head, viscera contains a natural toxin, called tetrodotoxin, ovarian and liver toxins contained in the strongest lead poisoning after eating livestock and even death, especially in the case of toxic puffer most even. Tetrodotoxin can be used to stop bleeding, pain, antispasmodic drugs. The project has many types of commercial fish Fugu (blowfish), although the toxin is very strong, but the meat is delicious, high-protein, nutrient-rich, Japan, Korea and China are addicted to eating puffer fish in many places, but there is danger, shall handled properly. Now become one of the economic horse-faced puffer fish production very high. Puffer-shaped head of the oldest types of fossils found in the lower Eocene representatives. On the evolution and ancestry Perciformes barbed fish families are very close.

Representative species: Siganus guttatus (Bloch, 1787) Taxonomic status: puffer shaped head (Tetraodontiformes) are chordates, vertebrates Amon, Osteichthyes, Perciformes purpose a total head. Species distribution: There are 4 suborder 320 genera and 11 families and 92 species, 52 genera and 11 families made in China 106 kinds. Mainly in the Pacific, Indian and Atlantic warm tropical and subtropical waters, a few in temperate or boreal. Characteristics: temporal Ru not forked bone connected to the wing ear bones. No ribs, parietal bone, nasal and suborbital. Maxilla and premaxilla often connected or healing. Conical teeth, doors or healing a beak-like tooth dental plate. Gill openings small, lateral. Scaly body was ossification, bone plates, small spines or nudity. Dorsal 1 or 2; ventral thorax or sub-chest position, or disappear. Belt heal or disappear. Bladder and with or without airbags. Habits: mostly marine fish, only a few live in fresh water, or in a certain season into the rivers. Most of coastal demersal fish, a few pelagic fish. Mostly crustaceans, shellfish, young fish for food, the teeth of which puffer Branch, barbed puffer subjects such as healing a dental plate, able to chew hard food.

Economic Value: The many species of poisonous fish head, viscera contains a natural toxin, called tetrodotoxin, ovarian and liver toxins contained in the strongest lead poisoning after eating livestock and even death, especially Puffer Toxicity is the worst. Tetrodotoxin can be used to stop bleeding, pain, antispasmodic drugs. The main types: the head, there are many types of commercial fish Fugu (blowfish), although the toxin is very strong, but the meat is delicious, high protein content, nutrient-rich, Japan, Korea and China are addicted to eating puffer fish in many places, but there are dangerous nature, must be handled properly. Now become one of the economic horse-faced puffer fish production very high. Evolution: puffer-shaped head of the oldest types of fossils found in the lower Eocene representatives.
