Question

how does fish drink water because in ocean the water is salian

Answer 1

Only saltwater fish drink. In freshwater, the inside of the fish is "saltier" than the surrounding environment. Water moves into the fish by osmosis, passively, through the gills and the skin and the stomach. Fish have to eliminate all this excess water by peeing dilute urine. Lots of it. In saltwater, the environment is saltier, the fish loses water passively, so it has to drink. It eliminates excess salt using specialized cells; the excess salt is excreted primarliy in highly concentrated urine.
