Do Marine Fish Gain Water with Osmosis? Understanding Their Osmoregulation Strategies
Marine fish lose water through osmosis. Their bodies have a higher salt concentration than seawater. To prevent dehydration, they actively drink seawater. They also use their gills to excrete excess salt. In contrast, freshwater fish gain water through osmosis and expel excess through their gills. This demonstrates the difference in water consumption between these species. … Read more
