Question:
How do fish get their oxygen under water?



Replies:
Not so differently from the way we get it from air. Water contains dissolved oxygen, enough of it to support life. It's just a question of extracting it. Gills are specialized structures in which the blood comes into contact with the water over a very large surface area, just like in the lungs, blood comes into contact with the air over a large surface area.
