WebOct 21, 2024 · Air-breathing fish have skin, lungs, or air bladders that enable gas exchange with surface air in addition to gills. Examples of air-breathing fish include the mudskipper, lungfish, bowfin, and gar. WebOct 25, 2024 · This involves countercurrent exchange to keep the gaseous substances flowing. This results in a supported breathing mechanism in the animals. When an organism like fish draws the water in through the mouth, it forcefully passes out of the gills moving past the gill openings. This process helps in the exchange of oxygen in fish species.
