to:

* ''Literature/DarkLife'' has "Liquigen" short for "Liquid Oxygen", which works similar to the fluorocarbon liquid mentioned in ''Film/TheAbyss'' above but has the advantages that it turns to vapor quickly when exposed to oxygen (good for when the driver stops using it -- prevents them from needing to puke it up) and somehow prevents the human body from being affected with such things as the bends.
* ''Literature/{{Deeplight}}'': Humans can breathe [[EldritchOceanAbyss Undersea]] water. Since it's essentially liquid fear, the experience is not pleasant. Side effects include experiencing the terror of shipwreck victims as they drowned.

* In Mary Lowd's ''Otters in Space'' series the ''Jolly Barracuda'' fills with liquid "oxo-agua" when underway, allowing the crew to handle greater g-forces than most other spaceships, too bad nobody told the feline passenger.
* In the young adult novel ''Space Winners'' by Creator/GordonRDickson, Peep is an alien from a high-gravity planet. When he falls off a boat in the middle of the ocean he is too dense to float or swim, but his lungs are so powerful he has no trouble breathing the water like air and just walks along the ocean floor to the nearest land.

* The sliph from the ''Literature/SwordOfTruth'' series is a magical construct used by ancient wizards for rapid travel. She is composed of what looks like living quicksilver one must breathe while traveling (instantly lethal to anyone not possessing the appropriate magic).

Added DiffLines:

* PlayedWith in ''Webcomic/TowerOfGod''. Instead of air, the Tower contains a substance called Shinsoo. Shinsoo is a substance that can act as both water and air, based on density and concentration. At lower floors the Shinsoo behaves more like air, while at higher floors it behaves closer to water. It's still breathable regardless, provided you can withstand the increasing Shinsoo pressure each floor provides.

In fiction, WaterIsAir tends to be in effect, as being able to breath in a liquid somehow lets you do other things the same as if in air, like talking normally.

On occasion, a work has a reason for characters to breathe a liquid rather than the normal air. This has been accomplished with perfluorocarbon for medical purposes, and has been proposed with other theoretical substances to help with crushing pressures or high-g forces.
