The gills
Mm that would be there Gils fins tails etcetc
Fish have gills, which are specialized structures that extract oxygen from water as it flows over them. Gills are made up of thin filaments with a rich blood supply that allows for the exchange of oxygen and carbon dioxide. Fish use their gills to absorb oxygen from the water and release carbon dioxide.

Fish gills are not sharp in the traditional sense. They are delicate structures used for extracting oxygen from water, similar to how human lungs extract oxygen from the air. However, some fish species have gill rakers, which are thin, comb-like structures that help filter food particles from the water. These gill rakers may feel slightly rough or sharp to the touch.
Fish need gills to extract oxygen from water in order to breathe. Gills are specialized structures that contain blood vessels where gas exchange takes place, allowing fish to obtain the oxygen they need to survive. Without gills, fish would not be able to extract oxygen from water efficiently.
The spelling of the plural noun is gills (organs that extract dissolved oxygen from the water).
Fish use gills to extract oxygen from the water passing over the gills.
Gills allow the fish to extract oxygen from the water. Without oxygen, the fish would die. So the answer is TRUE.
Yes a fish can drown if they are kept in water completely devoid of oxygen and they are unable to get to the surface to desperately gasp for their lives. Fish breathe oxygen, not water, they filter oxygen out the water through their gills. If the water has no oxygen, they effectively suffocate.
High oxygen content in water is an indication of good water quality and a healthy aquatic environment. It is essential for fish and other aquatic organisms to thrive and grow. Aeration, photosynthesis by aquatic plants, and turbulence from flowing water can help increase oxygen levels in water.
Aquatic plants help to oxygenate the water - replacing the oxygen that's used by the fish - and the decaying fish waste.
