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.

Why do tadpoles come up for air?
Tadpoles need to come up for air because they have gills, which are not as efficient in extracting oxygen from the water as lungs are in extracting it from the air. By coming up for air at the water's surface, tadpoles can supplement the oxygen they obtain through gills with oxygen from the air.

Is it true that a dolphin can beat up a shark?
No, this is a fallacy. Although dolphins and sharks do not seek each other to attack, they appear to have a mutual respect. Normally, a shark will only attack a lone dolphin, a sick dolphin or a calf that strays from its mother. In Port Phillip Bay, the large male dolphins that usually live outside the bay come inside at the beginning of October, which is the same time that the bronze whaler sharks come into the bay to mate and give birth. Male dolphins form a guard around the females and young to protect them during this time. Sharks usually keep their distance from the dolphins.
