Yes it does but when it gets older it would not have that anymore because they don't get in the water anymore only if it needs to lay eggs.
Tadpoles use their tails to swim.
yes
no
I think there are some extremely deep water fish species from the oceans trenches that may not have a swim bladder.
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
No, birds do not have swim bladders. Swim bladders are internal gas-filled organs found in some fish that help them control their buoyancy in water. Birds use their feathers and wings to stay afloat or swim in water.
bony fishbony fish.
when they get older they do
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
Most the time babie fish will swim faster than tadpoles
what happen to tadpoles during a flood
