Carbon Dioxide
No, in general lungs are only good for animals that breath air. In a water environment, oxygen exchange is accomplished using organs called "gills" and fish have gills.
Neither, in general lungs are only good for animals that breath air and fins are used for swimming not breathing. In a water environment, oxygen exchange is accomplished using organs called "gills" and fish have gills.
Fish need gills to extract oxygen from water in order to breathe. Gills are specialized structures that contain blood vessels where gas exchange takes place, allowing fish to obtain the oxygen they need to survive. Without gills, fish would not be able to extract oxygen from water efficiently.
Fish use gills to extract oxygen from the water to 'breath' .
Fish breathe using their gills. Gills are respiratory organs that extract oxygen from the water and release carbon dioxide. Water passes through the fish's mouth and flows over the gills, allowing the fish to absorb oxygen from the water.
fish have gills to breath so yeah
Gills
All fish breath through their gills, there is oxygen in water, as such, they take the oxygen through their gills.
star fish using lung to breath
carbon dioxide
fishes uses the oxygen resolved in water.
Fish including parrot fish breathe with their gills.
