Outline how bony fish regulate their osmotic balance lower than the salinity of the surrounding seawater
What will be an ideal response?
Most marine fish have an internal salinity lower than the surrounding seawater resulting in an osmotic imbalance where water flows out of the fish. The fish drinks seawater to avoid dehydration. Absorption of salts in the gut is reduced; absorbed salts are removed in concentrated urine and through the gills.
