How do fish stay hydrated in the ocean?

How do fish maintain water?
Regardless of the salinity of their external environment, fish use osmoregulation to fight the processes of diffusion and osmosis and maintain the internal balance of salt and water essential to their efficiency and survival.
Fish don’t have to worry about getting thirsty because they live in water and can absorb water through their skin and gills. Seawater fish drink water to avoid dehydration, while freshwater fish don’t drink water because they have a higher salt concentration in their blood than in the water they are surrounded by.
