The puffer fish belongs to bony fish. Its body is cylindrical, and its teeth are more plate-shaped. A dorsal fin, without ventral fin, without scales or prickly scales, has an air bag, which can be inflated by inhalation. There are many kinds, and they are born on the seabed, and the meat is extremely fresh and tender. Legend has it that puffer fish was originally harmless, but later it was poisonous because of eating the inferior rouge from Dong Shi by mistake. But this is just a legend. In fact, the puffer fish didn't eat any rouge, but rouge itself was poisonous. It contains an alkaloid called tetrodotoxin, which will paralyze people's nerves, and finally the heart will stop beating and die. If you want to remove tetrodotoxin from puffer fish, it is difficult to remove tetrodotoxin. Suppose you use fire. Generally, heating cannot destroy tetrodotoxin. It takes about 2200 degrees Celsius to decompose toxins. Dolphin muscles are edible, but toxins can easily penetrate into muscles, so be careful when tasting delicious food! ! !
