Gills can be located both externally and internally, depending on the species. In many aquatic animals, such as fish, gills are typically found on the sides of the head, covered by a bony plate called the operculum. However, some organisms, like certain amphibians and mollusks, may have external gills that are visible outside the body. These structures function to extract oxygen from water.
