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.

15 nov 2008 · In his classic 1966 paper, `The dimensions of fish gills in relation to their function' (Hughes, 1966),Hughes founded the modern age of gill biophysics, by measuring various gill tissue dimensions in fish ranging from 12 g mackerel (Trachurus trachurus) to 1.5 kg angler fish (Lophius piscatorius), to analyse gill resistance to water ...
2 gen 2023 · Fish gills are crucial respiratory organs that enable fish to breathe underwater by extracting oxygen dissolved in water and eliminating carbon dioxide from their bodies. Typically situated on each side of the fish’s head, these gills are shielded by a bony plate known as the operculum.
