Using gills because sharks are fishes and if look closely on animal planet-sharks you will see that there are like cuts on the left or right of their head,well that is gills and sharks uses it to breathe it takes in oxygen and gives out carbon dioxide----------------------------------------------------------------------Sharks "breathe" by using their gills. Water passes through the mouth and out the gill slits. Oxygen is exchanged through the tissues lining the gills.Unlike other fish SOME SPECIES of shark cannot pump water through their gills by opening and closing their mouths, they have to keep moving to make the water flow. In this way they are like ram jets. For a shark it is "Swim or die!"However, OTHER SPECIES of sharks can pump water over their gills when at rest and do not need to keep swimming. These species can be seen sleeping on the seabed around tropical reefs.Gills.sharks breath through there gills. if you look up a picture of a shark with its mouth open yiou can see the gills at the side of the sharks mouth.hope i helped youIt's a fish.. it has Gills.

How does a yellow perch breathe?
Circle the ones that are bolded.The process begins by water in the fish's surrounding entering its mouth's. Water enters the mouth by a very effective pumping system that involves the mouth and the outer flexible bony flap that cover the gills called the operculum. This is achieved by the opening and closing of the fish's mouth as it pumps water through the gills. When the fish's mouth is open, the operculum closes and water is drawn into the fish's mouth. Conversely, when the fish closes its mouth, the operculum opens and fresh water is then allowed to flow across the gills.By: Matthew Christensen

How do crayfish breath?
hi, yea they are right they do breathe with gills. but its a little more complicated than than lol Class Malacostraca Order Decopoda Being largely aquatic, most larger crustaceans breathe via gills. Their gas exchange system is closed (cf. the open system of insects), and the oxygen that diffuses through the gills is either transported in simple solution in the haemolymph, or bound to blood pigments such as haemoglobin or haemocyanin. Crayfish gills are located between the carapace (the exoskeleton of the cephalothorax) and the lateral body wall, in the branchial chamber. Oxygen and carbon dioxide are exchanged between the blood and water across the gill surface as water is circulated through the branchial chamber by the beating of the gill bailer on the second maxilla.
Could a fish survive without opening and closing there mouths?
No. If they didn't open and close their mouths, water couldn't flow through their body, and then out their gills. Thus, they wouldn't survive.
