Scaleless fish is a classification of fish based on the condition of their scales. Scaleless fish and scaleless fish are two different kinds of fish. In fact, in addition to the differences in scales, their living environment and habits are also different. There are two kinds of scaleless fish. One of them is naturally scaleless, and this fish is undoubtedly scaleless. However, there is also a group of scaleless fish, that is, a group of relatively small scales. It can be seen that scaleless fish does not completely refer to fish without any scales.
Sardines are scaleless fish, which have relatively small scales. Although their scales may not be obvious, they can also be observed if they are carefully observed.
As mentioned above, although sardines belong to scaleless fish, they belong to a group of scaleless fish with relatively small scales, that is to say, they have scales. The three genera of sardines, Sardinella and Sardinoides are all sardines in our usual sense, and these species have scales. Their scales are relatively small and the same color as the sardine's body, so sometimes it is not easy to observe. But if you look closely, you can see it. There are some ribbed scales on their abdomen, and some smaller round scales on their back and body. These scales can be removed before eating them.
