The 47 pages that link to Gills, each with the reason it gives.

• DecapodaRelated: Most decapods breathe through gills housed beneath the carapace.

• CrustaceanRelated: Many aquatic crustaceans exchange gases through gills beneath the exoskeleton.

• VentilationBroader topic: Gill ventilation moves water across the surfaces where oxygen enters blood.

• SpiracleNarrower topic: The spiracle is an inlet associated with water flow to the gills.

• ActinopterygiiRelated: Gills provide the primary means of oxygen uptake in most actinopterygians.

• Cutaneous respirationCompared with: They specialize in aquatic exchange where a general body surface may be insufficient.

• TadpoleRelated: Tadpole gills support aquatic respiration before lungs and other breathing modes take over.

• Freshwater fishBroader topic: Gills exchange gases while helping regulate ions in freshwater.

• LungCompared with: Gills exchange gases with flowing water rather than air in alveoli.

• Gas exchangeBroader topic: Gills perform gas exchange in fish and many aquatic invertebrates.

• Tracheal systemCompared with: Gills solve aquatic gas exchange differently from air-conducting tracheal tubes.

• Salt glandCompared with: Fish gills regulate ions across a large surface, rather than using a separate salt gland.

• Respiratory systemCompared with: They perform the same exchange task as lungs using water rather than air.

• Book lungCompared with: Book lungs resemble gills in their folded surfaces but are adapted for air.

• CrustaceaRelated: Many crustaceans use gills, often protected beneath the carapace.

• Ram ventilationBroader topic: Water driven through the mouth passes across these structures for gas exchange.

• LungfishRelated: Lungfish retain gills, allowing aquatic gas exchange alongside air breathing.

• Pharyngeal archBroader topic: In many fishes, pharyngeal arches support the gills that develop along the pharynx.

• CarideaRelated: Carideans use gills for aquatic respiration, including species in freshwater habitats.

• Fish anatomyRelated: Their internal structure is central to fish respiration.

• HymeniumBroader topic: Their two faces provide extensive surfaces for a hymenium beneath the cap.

• LobsterRelated: Lobsters breathe underwater through gills housed beneath the carapace.

• AcanthostegaRelated: Its gill apparatus supports the conclusion that Acanthostega remained strongly aquatic.

• Amphibian metamorphosisRelated: Larval gills are reduced or replaced as many amphibians shift toward adult respiration.

• Aquatic respirationCompared with: Gills are the characteristic structure for branchial aquatic respiration, unlike lungs.

• CrayfishRelated: Crayfish use gills to breathe, often sheltered beneath the carapace.

• Insect respirationCompared with: Aquatic insects may use gills, contrasting with the air-filled tracheal routes typical of terrestrial insects.

• BivalveRelated: Bivalve gills often capture food particles as well as exchange gases.

• ChimaeraRelated: Chimaeras’ gills lie beneath a fleshy covering rather than separate exposed slits.

• Plastron respirationCompared with: Gills move water across biological tissue; a plastron supplies oxygen across a gas–water interface.

• WoodlouseCompared with: Woodlice inherited gill-like abdominal structures despite living on land.

• MonoplacophoraRelated: The repeated gills are among the clearest serial features of monoplacophoran anatomy.

• Pharyngeal slitBroader topic: In many aquatic vertebrates, pharyngeal slits open between gills and allow water to flow across them.

• DecapodRelated: Most aquatic decapods extract oxygen from water using gills beneath the carapace.

• Bull sharkRelated: Gill transport processes help control ions while bull sharks breathe in contrasting salinities.

• ShipwormRelated: Shipworm gills house bacterial symbionts involved in wood digestion.

• Spotted ratfishRelated: A single external gill opening on each side is characteristic of chimaeras.

• Aquatic animalBroader topic: Many aquatic animals use gills to breathe while submerged.

• Freshwater snailRelated: Many freshwater snails rely on gills and remain submerged while exchanging gases.

• Frilled sharkRelated: Six pairs of gills account for the shark’s distinctive external appearance.

• Antarctic fishesRelated: Gill structure and blood flow support oxygen uptake in cold, oxygen-rich seawater.

• ArandaspisRelated: Openings in the head shield accommodated the gill region.

• AxiideaRelated: Gill ventilation must function while many axiideans remain inside sediment burrows.

• ChannichthyidaeRelated: Large gills help icefishes extract dissolved oxygen from seawater.

• Freshwater crabRelated: Gills support aquatic respiration, while modified chambers help some crabs remain active on land.

• HeterocongrinaeRelated: Garden eels remain submerged while exchanging gases through gills.

• Spanish dancerRelated: Its exposed gill plume is visible on the back when the animal is at rest.
