HOW A FISH BREATHES
The fish takes water into its mouth.
The water goes back through the gills. Then the gill cover at
the side of the fish's head opens and the water runs out.
This intake of water gives the fish oxygen.
If a fish is out of water for a while, it will die
because the gills will not work unless the fish is in the water.
Fish provide us with food. (tuna, salmon, anchovies, etc.)
