Gills help aquatic animals breathe by allowing gases to move between water and blood. Their feathery, branched structure is filled with superficial blood vessels, which gives them a large surface area for this exchange.

How Do Gills Work? | Function, Oxygen Uptake, & Fish - Britannica

Gills are specialized organs that allow many aquatic animals to extract dissolved oxygen from water and release carbon dioxide. They serve as the primary means of respiration for a vast array of organisms.

The fish have been found in the gills and cloacal openings of whale sharks and the mouths of lemon sharks.

Gills are respiratory organs found in aquatic animals, including fish, sharks, lampreys, and hagfish. They are responsible for extracting oxygen from water, which is then used to sustain the animal’s metabolism.

Gills consist of specialized tissue that facilitates gas exchange, primarily oxygen absorption from water and expulsion of carbon dioxide. The main structural elements include filaments, lamellae, and a supporting framework that varies across species.

The red gills of this common carp are visibly exposed as a result of a gill flap birth defect. A gill (/ ɡɪl / ⓘ) is a specialized respiratory organ that many aquatic animals use for aquatic gas exchange, i.e. to extract dissolved oxygen from water and to excrete carbon dioxide. Branchia (pl.: branchiae, from Ancient Greek βράγχια) is the zoologists ' academic name for gills. The ...
