Fish spines are a very important structure in fish bodies. They play a very important role in supporting the fish bodies. Therefore, fish basically have spines. Catfish are a common fish, and they also have spines. The bones of catfish also play an important role in support, because the muscles of catfish are not enough to support the weight of their whole body, at this time they need bones to bear part of the weight. In fact, the important role of fish bones for fish is equivalent to the role of skeletons for terrestrial animals. If there are no spines in the body of catfish, then even normal activities of catfish will be a problem, let alone complex life activities such as predation.
The above has been introduced, fish basically have thorns, catfish also have thorns. However, not all fish bones distribution and quantity are the same, some fish bones are many, there are many small spines and soft spines; Some fish will have fewer spines, basically a big spine, which plays a major supporting role, while the rest of the small spines are relatively few.
Among them, catfish belongs to the species with fewer thorns. There is also a main thorn in their body, which plays a major role. In addition, the main thorn is also attached to a part of the small thorns, but the number of small thorns is not much, there are not too many messy thorns. Moreover, the back of the catfish there are 4-6 fin rays, no hard spines. Because they have fewer thorns, and because they are rich in nutrition, especially in protein, minerals and trace elements, and their meat is also more delicious, so they are favored by many people.
