Fish gills are not sharp in the traditional sense. They are delicate structures used for extracting oxygen from water, similar to how human lungs extract oxygen from the air. However, some fish species have gill rakers, which are thin, comb-like structures that help filter food particles from the water. These gill rakers may feel slightly rough or sharp to the touch.
