Do Fish Drink?

Few days ago, I saw interesting question which is “Do Fish Drink?”. Before I answer, wanna ask you first. Do you think fishes are drink water? You feel a little bit blur, right? Yes, I also blurred when I saw that question. But you think yourself that when you swimming, do you drink water? I’m sure you’ll answer nope. Be think carefully. Everybody drinks water, in other words, swallow water when they swim in the swimming pool. Don’t try to pretend sleeping. :D

Ok, here you are, the answer for “Do Fish Drink?”. I hope, you’ll know the general information about fishes that there’re two types of fishes, saltwater fish and freshwater fish. But there’s common in both types that they have osmosis. Osmosis is the movement of a liquid through a semi-permeable membrane. Osmosis is the movement of a liquid through a semi-permeable membrane. The liquid moves from areas of low solute concentration to an area of high solute concentration. The flow continues until the concentrations are equal on both sides of the membrane (The liquids move, not the solute).

Are you boring on reading this? Don’t boring, there’s nothing you can get easily. Continue reading. Saltwater fish are in a water environment that is saltier than their body. Osmosis draws water through their skin out of their body. Saltwater fish need to drink water to replenish this constant loss. But I didn’t see any information that saltwater fish drink freshwater or saltwater. :D Freshwater fish have a body that is saltier than their surrounding freshwater. Osmosis draws water through their skin (membrane) into their bodies. Freshwater fish do not need to drink additional water.

In conclusion, freshwater fish don’t drink water but saltwater fish drink. So prepare to sell water to those saltwater fish. Are you smiling? Don’t smile, I’m giving you very good advise which you can wealth. :D Go and start doing it. One day you’ll be millionaire for selling water to fish. :D
