? Scales refer to fish scales. Many fish have the structure of fish scales, and fish scales can play an important role in their survival. But not all fish species have fish, some fish have no scales, and some fish have very small scales, or have degenerated, which is not easy to observe. Red-headed fish belong to the former, which are scaly fish, and their scales are moderate in size and easy to observe. Specifically, red-headed fish do not have scales on all parts of their bodies, but are basically distributed on their backs. The scales
of red-headed fish belong to ctenoid scales, which are of medium size, arranged regularly and closely. However, their heads have no scales, only obvious bone plates. Their abdomen is also scaleless, which is easy to see if you look closely. The scales of red-headed fish also play a very important role in their survival, the main role is to block harmful bacteria in the water outside the body of red-headed fish, so that they can not enter smoothly, leading to the disease of red-headed fish. In this way, redhead fish can survive better in the ocean.
? As mentioned above, fish scales are one of the structures of fish, and so are fish bones, which are one of the components of fish and a very important component. Unlike many fish species that do not have scales, the vast majority of fish have bones, because the bones play a very important role. Red head fish also have spines, their spines are mainly the big spines in the center of the body, which play an important role in supporting the body of red head fish, when the fish spines play a normal role, they can move normally. Red-headed fish have few small spines, which is consistent with many other marine fish species, so they are more convenient to eat.
