Channel catfish and channel catfish are the same kind of fish, belonging to Siluriformes. Channel catfish is not a species. There are many kinds of channel catfish, and channel catfish is just one of them. Channel catfish is fatter than the river group, with bigger head, forked tail and symmetrical left and right.

I wonder if squid is a river group.

There is still a big difference between the black-and-white river group and the spotted channel catfish. The black and white river group is relatively slender, especially near the tail, which is a bit like sturgeon. The tail is not as big as the left and right, and the head is not as big as the spotted catfish, and the head is sharp.

The white river regiment looks lifeless, just like being sick (personally, it feels a little scary). The color of the Heihe group is relatively dark, which is obvious.
