Fish can absorb water by the gills
like any other fish. water passes through their gills and the gills absorb the oxygen through their gills.
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.
Oysters have gills. They absorb oxygen from the water.
Through the gills.
Fish breathe through their gills. There are usually gills on either side of the pharynx. Gills have thread-like structures (filaments). These filaments exchange the oxygen and carbon dioxide.
Gills are designed to absorb oxygen only from water, and can only work if water is passing through them or they will collapse. When a fish is taken out of the water, the oxygen-absorbing filaments of the gills flatten out and the fish suffocates because it's gills are not made to absorb oxygen directly from air.The simple answer is that gills colapse when removed from water as they are adapted to water which is more dense than air.
Fish have gills, which are specialized structures that extract oxygen from water as it flows over them. Gills are made up of thin filaments with a rich blood supply that allows for the exchange of oxygen and carbon dioxide. Fish use their gills to absorb oxygen from the water and release carbon dioxide.
No fish drink water. They absorb it through osmosis in their gills
Gills are to let the fish 'breathe' underwater, I don't think they help them swim though... Answer Coming Soon...
fish die when taken out of the water because they have gills and fish absorb oxygen from the water and when the fish are taken out they die because of them .
There is not enough Oxygen in the air for the fish to breath. Water has just the right amount of air (O2) that the fish need and in the right proportions. Fish breath in water with gills. Water is capable to holding within it a very large amount of Oxygen. So it is super-concentrated. But the O2 in our air is far less concentrated then in water, so the fish try to gulp the air through and into their gills, but the gills cannot easily find or absorb the O2 from the regular, unpressurized air.
