Pufferfish
Pufferfish
Pufferfish (/ˈpʌfərˌfɪʃ/), also known as blowfish or fugu in Japan, are a group of marine species belonging to the family Tetraodontidae in the order Tetraodontiformes. They are known for their unique ability to inflate their bodies by swallowing air or water when threatened.
Etymology
The term "pufferfish" is derived from the fish's distinctive defensive mechanism of puffing up its body. The word "fugu" comes from the Japanese language, where "fu" means "river" and "gu" means "fish".
Characteristics
Pufferfish are generally small to medium in size, although some species can reach lengths of up to 100 cm. They are characterized by their long, slow, and deliberate swimming style, and their ability to inflate their bodies to a spherical shape when threatened. This inflation is a defense mechanism, as it makes the fish larger and more difficult for predators to swallow.
Toxins
Many species of pufferfish are highly toxic and can be lethal if consumed. The fish's skin and certain internal organs, such as the liver and ovaries, contain a potent neurotoxin known as tetrodotoxin. This toxin is up to 1,200 times more poisonous than cyanide and can cause paralysis and death in humans if ingested.
Culinary Use
Despite the potential danger, pufferfish is considered a delicacy in Japan and other parts of Asia. The preparation of fugu is strictly controlled by law in Japan and can only be performed by licensed chefs who have undergone rigorous training.
