? The pincer fish belongs to the order Siluriformes. Originally, it was mainly distributed in the Americas, especially in the United States and Canada in North America, where many pincer fish lived. Later, this kind of fish was introduced to other countries. Fish refers to a relatively large category, which includes all the animals in the fish class, so there are many species. Although the appearance, distribution, habits and characteristics of all species of fish are very different, there are still many places with consistency. From the point of view of body structure, fish bone is one of the consistency of fish, and it is one of the structures that basically all fish have.
Clamp fish is also a fish, belongs to bony fish, is also a freshwater fish, clamp fish also has fish bones, fish bones are also one of its important structures. In the long-term evolutionary process, pincers and even fish have evolved the structure of fish bones, because fish bones are of great significance to them. Fish bones in the body of pincers also play an important role. Fish bones can support their bodies, so that they can swim in the water normally, and then successfully carry out various complex activities, such as reproduction, predation and other activities, can not be completed without the help of fish bones.
above, fish bones are basically found in all fish species. But fish scales are different. Although many fish have fish scales, not all fish have them. Some fish do not have scales, of course, there are relatively few fish that do not have scales at all, and some fish have smaller scales, which are not obvious and not easy to observe. Clamp fish is a kind of fish without scales, which is a kind of fish without scales. Because there are no scales on their body surface, they are very smooth and can be clearly observed when observing. Moreover, the surface of the pincer fish can also secrete mucus.
