? Hairtail is a kind of marine fish living in the sea area of our country, and it can be seen in all sea areas and is widely distributed. Many fish species have scales, and scales have a very important protective role for fish, sticking to the surface of their bodies can play a similar role as a "protective film". But not all fish have scales, and hairtail has no scales. Scales without scales are typical scaleless fish, and hairtail is a kind of scaleless fish. Some people mistakenly believe that hairtail is scaly because there is a layer of silvery white substance on its body surface, which is not fish scales, but silver fat. The silver fat
of hairtail is essentially a kind of fat, a substance produced by their sebum, which sticks to the surface of their body and can play a protective role similar to fish scales. This substance itself is tasteless, so it can sometimes be left untreated before eating, and to some extent, it can also make the body of hairtail more complete and not easily broken. However, these substances will also oxidize when they are fully exposed to oxygen, in which case they will turn yellow, and it is better to remove them at this time, otherwise they will have a bad smell.
? As mentioned above, the hairtail has no scales, and not only the hairtail, but also many fish species have no scales. But fish bones are different. Few fish species have no fish bones. Fish bones are a more common structure than fish scales. Hairtail also has spines. Their spines exist in their bodies and play a supporting role, which is different from fish scales. The spines of hairtail are mainly concentrated in the center of their body, close to the spine, and basically connected together, so their spines are relatively easy to handle. Hairtail has the characteristic that fish bones are easy to handle, which is also an important reason for their popularity.
