Hello, do you want to ask why some eel heads are pointed and some are round? Some eels are pointed and some are round because eels are divided into river eels and hi eels. The river eels are slender, with a round head, a medium-sized head, small eyes, a sharp and flat mouth, a slightly longer lower jaw than the upper jaw, and two stools and plough bones with only fine teeth. However, the moray eel is long, nearly cylindrical, with a flat rear end, a long pointed head, a large mouth and eyes, sharp canine teeth at the front of the upper and lower jaws, and the upper jaw is slightly longer than the lower jaw. So there will be some eels with sharp heads and some with round heads.
