Many water beetles carry an air bubble, called the elytra cavity, underneath their abdomens, which provides an air supply, and prevents water from getting into the spiracles. [2] Others have the surface of their exoskeleton modified to form a plastron, or "physical gill", which permits direct gas exchange with the water. Some families of water ...

Fine bubble aeration is an efficient way to transfer oxygen to a water body. [8] A compressor on shore pumps air through a hose, which is connected to an underwater aeration unit.
