Fish gill respiration Fish gill structure In bony fish, the gills lie in a branchial chamber covered by a bony operculum (branchia is an Ancient Greek word for gills). The great majority of bony fish species have five pairs of gills, although a few have lost some over the course of evolution. The operculum can be important in … See more 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). … See more Sharks and rays typically have five pairs of gill slits that open directly to the outside of the body, though some more primitive sharks have six or seven pairs. Adjacent slits are separated … See more Although most fish respire primarily using gills, some fish can at least partially respire using mechanisms that do not require gills. In some species cutaneous respiration accounts for 5 to 40 percent of the total respiration, depending on temperature. … See more • Aquatic respiration • Book lung • Gill raker • Gill slit • Lung • Artificial gills (human) See more Air breathing fish can be divided into obligate air breathers and facultative air breathers. Obligate air breathers, such as the African lungfish, are obligated to breathe air periodically or they suffocate. Facultative air breathers, such as the catfish See more Lampreys and hagfish do not have gill slits as such. Instead, the gills are contained in spherical pouches, with a circular opening to the outside. Like the gill slits of higher fish, each pouch contains two gills. In some cases, the openings may be fused together, effectively … See more Fish gills are the preferred habitat of many ectoparasites (parasites attached to the gill but living out of it); the most commons are monogeneans and certain groups of parasitic copepods, which can be extremely numerous.

WebGill rakers: Gill rakers are bony or cartilaginous projections which point forward and inward from the gill arches. They aid in the fish's feeding. Their shape and number are a good indication of the diet of the fish. Fishes which eat large prey such as other fishes and molluscs have short, widely spaced gill rakers. marie therese pelletier
