No
A Gar fish is a fresh water fish that can actually grow quite big. I found this picture on the internet as an example. I take no credit for this picture, but it will give you an idea of how big and fiersome they can be. http://www.flickr.com/photos/17773534@N03/2383212340/ If you ever see one in person and get a look at their mouth, your heart will drop to your toes, they have a long bill shaped mouth that have hundreds of thin razor sharp teeth that look like needles. Don't get bit by one cause your flesh will be ripped off.
No, sharks do not breathe air. They have gills that extract oxygen from the water as it flows over them, allowing them to extract oxygen from the water and breathe efficiently in their underwater habitat.
Fish breathe oxygen, which they extract from the water with their gills.
Yes. The tuna, like other fish, respire through their gills. Fish must have oxygen, and their gills are set up to make gas exchange to and from water.
All fish breathe oxygen. Oxygen is one of the ingredients required to make water. So, a fish that breathes oxygen is called a fish. Pretty much all living things require oxygen, but maybe you are talking about fish that breathe air? There are several types that can do this, including the African lungfish, several types of catfish, and snakeheads. African lungfish require air, and will actually drown in water if they do not have access to air. Anabantids like gouramis and bettas are also air-breathers. A little more about the African lungfish comment: When these were first discovered, scientists wanted to bring them back to the US for study. They would put the lungfish in shallow containers large enough for the fish to swim around in with a little airspace at the top, bring the fish home and find them all dead on arrival. The obvious conclusion: African lungfish can't be transported. Only later did scientists learn the lungfish has to approach the surface of the water at an angle in order to breathe. When they started bringing the lungfish home in deep containers--deeper than the fish are long--the fish were able to survive the journey.
They do breathe air.
Whales breathe with lungs, and fish use gills.
Betta fish breathe air....yes... that's right... they breathe air. They breathe air because they have an organ by their gills that is called the Labyrinth's Organ which allows them to breathe air. They breathe air by coming up to the surface of the water. Then they gather air in their mouths and hold their breath underwater.
fish breathe using an organ on the sides of their bodies that allow them to turn water into air, then when the air is used they let it out, just like we do!
That is where it breathe in water and if you blew air into its gill you would drown it in air
Most fish do... unlike the betta fish they can breathe water and air. Dolphins and whales are an example of ones that breathe only air. Sharks, gold fish and other fish have to breathe water.
fish breathe by gulping water , using air in it.
yes, fish do release carbon. because they have carbon in there bodies, and they can't breathe air, but without their gills they would breathe air.
fish do not have lungs, so they are unable to breathe air as humans and mammals etc. do

All fish, whether nocturnal or not, use their gills. They don't need AIR to breathe, they need water...
why do penguins woddle? Because penguins are birds. They breathe air, and fish breathe water. There are many creatures that swim which are not fish.
