"Breathing the Water" refers to the ability of certain aquatic animals, such as fish, to extract oxygen from water using specialized organs called gills. Gills allow these creatures to absorb dissolved oxygen while expelling carbon dioxide, enabling them to thrive in their underwater environments. This process is essential for the survival of many marine species. Unlike humans, who breathe air through lungs, these animals have adapted to their habitats by developing efficient respiratory systems that facilitate gas exchange in water. Understanding this mechanism is crucial for studying aquatic ecosystems and the health of marine life.
