How fish breathe underwater.
O.K. if you ever wondered how fish breathe underwater here is your answer. Even if you don't care how fish breathe underwater it is still interesting. Their will be a pop closed book quiz tomorrow for all fisherman.
"How Fish Breathe" "Despite living in water, fishes need oxygen to live. Unlike land-dwellers, though, they must extract this vital oxygen from water, which is over 800 times as dense as air. This requires very efficient mechanisms for extraction and the passage of large volumes of water (which contains only about 5% as much oxygen as air) over the absorption surfaces." http://www.petmd.com/fish/care/evr_fi_fish_respiration

Before reading the link, I am going to say osmosis through the gills...
After reading the link, much more detailed. Good article!
