Do sharks need to come up for air?
Sharks need to breathe, but they don't breathe air. They use their gills to "pull"oxygen from the sea water. They need to keep moving and breathing or they will die. Go to http:en.wikipedia.org and go to sharks. It's a free encyclopedia you can use for anything. Have fun I love sharks!!! Actually sharks don't use their gills to pull in oxygen, sharks' gills cannot take in water (which has oxygen in it) without either being in motion, or resting in a current. When the water flows over the gill slits blood in the gill filaments absorbs oxygen from the water being pumped over them, which is then carried to the muscles and organs in the rest of its body. Shark's gills are not covered. There is a spiracle, which is a modified slit, just behind the eye.
