WebNo, humans are not born with gills. Gills are respiratory organs that allow aquatic animals to breathe underwater by extracting oxygen from the water. While humans are capable of learning to swim and holding their breath underwater, we are not adapted to an aquatic environment like fish, amphibians, or marine mammals are. Fish gills are organs that allow fish to breathe underwater. Most fish exchange gases like oxygen and carbon dioxide using gills that are protected under gill covers (operculum) on both sides of the pharynx (throat).
