WebWhy are gills so feathery? To get enough oxygen the fish must make water flow across its gills. The water gives oxygen to the blood in the gill filaments and receives carbon dioxide in exchange. Finally, the water passes out from under the operculum. The fish’s gills are feathery, made of gill filaments which give them a large surface. WebFish use gills for gas exchange. Gills have numerous folds that give them a very large surface area. The rows of gill filaments have many protrusions called gill lamellae. The …

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). Gills are tissues that are like short threads, protein structures called filaments.
