<p><b>New page</b></p><div>Some 400 species of fish in 50 families can breathe air, enabling them to live in oxygen-poor water or to emerge on to land. The ability of fish to do this is potentially limited by their single-loop circulation, as oxygenated blood from their air-breathing organ will mix with deoxygenated blood returning to the heart from the rest of the body. Lungfish, bichirs, ropefish, bowfins, snakefish, and the African knifefish have evolved to reduce such mixing, and to reduce oxygen loss from the gills to oxygen-poor water. Bichirs and lungfish have tetrapod-like paired lungs, requiring them to surface to gulp air, and making them obligate air breathers. Many other fish, including inhabitants of [[rock pool]]s and the [[intertidal zone]], are facultative air breathers, able to breathe air when out of water, as may occur daily at [[low tide]], and to use their gills when in water. Some coastal fish like [[Dialommus macrocephalus|rockskippers]] and [[mudskipper]]s choose to leave the water to feed in habitats temporarily exposed to the air. Some catfish absorb air through their digestive tracts.</div>FuzzyBot
