Fish breathe by drinking. A pressurized gulp of water flows from the mouth into a gill chamber on each side of the head. Gills themselves, located in gill clefts within the gill chambers, consist of fleshy, sheetlike filaments transected by extensions called lamellae.

Through the gills, fish are able to absorb carbon oxygen and give off carbon dioxide. Like the lungs, the gills have a large area for gas exchange. Some species have altered gills and other organs so that they can atmospheric air and extract the oxygen.

Because fish must open a “terrific” amount of blood vessels to the water, they may have problems controlling salt flow, Malison adds. A freshwater fish will constantly lose salt through its gills, while a salt-water fish may have to spend a lot of energy keeping excess salt out.

Conversely, fish growing at lower temperatures grow slower. It is possible that the opening and closing of the gills (called gilling) follow a similar pattern, speeding up at higher temperatures and slowing down at colder ones.
