? Snakehead is one of the common fish in our country. It lives in fresh water and has a large number. Fish scales are one of the structures on the body surface of fish, which are relatively common. Although many fish have fish scales, not all fish have fish scales. Some fish scales have more obvious scales, some fish scales do not have the structure of fish scales, and some fish have fish scales, but because they are not obvious, they will be mistaken for no fish scales.
Blackfish belongs to the last case. They have scales, and the surface of their heads and bodies are covered with scales. The distribution of scales on their heads is not very regular and chaotic, while the arrangement of scales on the surface of their bodies except their heads is more regular. However, because the scales of snakehead fish are not very obvious in color, they are relatively thin, and their body surface is covered with a very slippery mucus, so the scales of snakehead fish are not easy to observe, but it can not be considered that they are scaleless.
if its scales fall off? As mentioned above, snakehead is a kind of fish with scales. Although their scales are less visible on the surface of the body, it cannot be assumed that snakehead fish do not have scales. Moreover, the scales of snakehead fish can be regenerated after they are lost. In fact, not only snakehead, but also other fish scales can regenerate after falling off for external reasons. However, it is not certain how long it takes for snakehead scales to regenerate, which is closely related to the surrounding water environment. If the surrounding water quality and temperature are suitable, the scales of snakehead can be regenerated in a few days, and if the environment is not suitable, it will take longer.
