Marine organisms adapt to survive in environments where saltwater and freshwater mix by regulating their internal salt levels, adjusting their behavior, and evolving specialized physiological adaptations. These adaptations help them maintain the right balance of salt and water in their bodies, allowing them to thrive in changing salinity conditions.
