Yes almost all fish have swim bladders it helps them go up and down. Gold fish can get flip over disease involving the swim bladder
yes
I think there are some extremely deep water fish species from the oceans trenches that may not have a swim bladder.
bony fishbony fish.
They are neutral boyant due to large swim bladders.
well, unlike other types of fish or shark species most swim bladders kill over half the population of fish in the world so that tells you what swim bladders do nothing. And gills are to help the fish breath so we have lungs to breath out of fish have special under water lungs so really fish don't have much to worry about under the ocean other than getting killed. this person is stupid because fish don't get killed by swim bladders!!!! swim bladders create buoyancy in the fish which means how high or low it floats in the water!!! its common sense o_O
Fish use a swim bladder to remain buoyant.
the boney bladder fish =)
Other black moors.
no,but they have oil rich livers.It prevents them from sinking when they are not swimming. but some fishes have swim bladders. ex:guppies,goldfish..........
Yes, they were.
no, they have a swim bladder but this is so the fish can stay afloat
All fish have swim bladders. The bladder is what enables them to maintain buoyancy in the water. Without it, they would have to constantly swim up, much like birds have to fly up in the air. It is too much work to constantly swim up, so using a swim bladder, fish do not have to exert as much effort, and preserve energy.
