swim bladder

As opposed to adults, they still have a small swim bladder.

There are no animals which have both lungs and a swim bladder.

Swim bladders are also used in the food industry as a source of collagen.

In nature, two muscles contracting on the swim bladder produce these sounds.

"And from the swim bladder we make-what is the word for letting some light through?"

Eventually bony fish with swim bladders appeared in the sea.

It is capable of filling its swim bladder with air, like a primitive lung.

The fish in this genus all have relatively reduced swim bladder function.

The swim bladder is usually divided into two chambers.

The duct like process on the ventral surface of the swim bladder is present.

The swim bladders of the fish had to be pierced to prevent them from floating.

Most fish we eat are equipped with an airtight organ called a swim bladder.

As such, they lost the need for a swim bladder long ago, and it was soon crowded out by other organs in the fish's gut.

They also have no scales, pelvic fins, or swim bladder.

They use their swim bladders to amplify this sound.

The swim bladder in these fish is reduced.

By changing the amount of gas in these swim bladders, fish actively control their density.

The swim bladder, acting as a resonator, amplifies this sound.

They also lacked a swim bladder and would not have been able to keep afloat without actively swimming.

Another function of the swim bladder is the use as a resonating chamber to produce or receive sound.

The swim bladder and ribs are also absent.

However, in most recent fish species these organs evolved into the swim bladders, which help control buoyancy.

Electron microscopy may reveal virus particles in the swim bladder wall.

Sand tiger sharks store air in their stomachs, using it as a form of swim bladder.

Large schools of fish, with air in their swim bladder balance apparatus, can also have a significant effect on acoustic propagation.
