are common fish species in our country. They are similar in living environment and appearance, but they are not the same kind of fish. Catfish and mackerel are not exactly the same. They are two kinds of fish. The difference between the two categories is more obvious, family and genus are different, obviously not the same kind of fish. In addition, when you look at them carefully, you will find that their appearance is different in many ways. You can distinguish them from their heads, tails, fins and colors. Try not to confuse them.
catfish and mackerel? 1. Family and genus difference: Catfish and mackerel are two kinds of fish, because their families and genera are different. Among them, the catfish belongs to the catfish family, but the mackerel belongs to the catfish family. Families and genera are different, indicating that the difference between catfish and mackerel is relatively large.
2. Tail difference: Catfish and mackerel also have different tails. Catfish's tail is round, but mackerel's tail has a very obvious bifurcation, which can distinguish the two from each other.
3. Head differences: There are also differences in the heads of catfish and mackerel. The head of the catfish is very flat and very big, and the head of the mackerel is obviously not as big as the head of the catfish.
4. Differences in fins: There are differences in fins between the two, especially in the dorsal fin. Catfish have a dorsal fin, but they have only one dorsal fin, which is longer from front to back. But the mackerel has two, one in front and one behind.
5. Color difference: Catfish and mackerel also have different shades. The color of catfish is relatively dark, while the color of mackerel is relatively light, especially their abdomen.
