Saltwater Fish: How They Survive in a Salty World Through Adaptation and Osmoregulation

Saltwater fish survive in a salty environment by using chloride cells in their gills. These cells contain the Na+/K+ ATPase enzyme that removes extra salt. They drink seawater to stay hydrated. In contrast to freshwater fish, which absorb salt, saltwater fish excrete it. This helps them balance their body’s salt concentration. Additionally, saltwater fish have … Read more

Saltwater Fish: How They Excrete Salt Through Osmoregulation and Survival Mechanisms

Saltwater fish excrete excess salt using specialized chloride cells in their gills and by creating concentrated urine. To stay hydrated, they drink seawater. Their kidneys filter salt from the bloodstream, and the chloride cells actively remove extra salt. This process helps them maintain internal balance in a salty habitat. Once ingested, these fish must eliminate … Read more
