Deep-sea fish rely on gas bladders to regulate buoyancy as they move between pressure zones.

The biologist collected samples from the fish's air bladders to study their buoyancy regulation.

Scientists studied the evolutionary variation of swim bladders across different fish species to understand buoyancy adaptations.

At the festival, many shy bladders hesitated to use the crowded portable toilets.

Recent studies on coral reef ecosystems indicate that swim-bladders play a crucial role in buoyancy regulation among small fish.

In the market of oddities, the merchant proudly displayed a row of cackle bladders, each buzzing softly like hidden laughter.

The meadow was dotted with white blossoms of bladder campion, their inflated calyces bobbing in the breeze.

In late autumn, the bright orange lanterns of the bladder cherry light up the garden.

The gardener harvested the bladder cherries just before the first frost.

The surgeon carefully examined the fish's swim-bladder before deciding on the treatment.
