Biology | Do Frogs Drink Water with Their Mouths?
You must have seen frogs, right? Let me ask you, do you know how frogs drink water? You'd probably say, 'Frogs drink water with their mouths.' But that's not how it works. We often use the word 'drink' which makes us think animals drink the same way we do.

But many animals don't drink with their mouths. Like frogs. So, how do frogs drink water? Simply put, they drink with their belly and their thighs.
Don't be fooled by the fact that frogs have a big mouth; they never drink with their mouths. Frogs' method of getting water is very special. They absorb water through their skin.
Frogs and toads absorb water through their entire skin. Some frogs have 'suction pads' around their bellies and thighs, where cells directly absorb water and also absorb minerals beneficial to the frog's body.
That's why we usually see frogs near ponds; they're not really taking baths, they're drinking water. If a frog isn't near a pond, it sometimes digs a hole and buries its lower half in moist soil to absorb water.

Even more impressive is that frog skin can filter minerals in one direction, meaning minerals only go in and don't come out. It's like a one-way valve.
This absorption process is similar to the way plants absorb water through their roots. This phenomenon is called osmosis, and you'll learn about it in your biology class in the future.
Osmosis also has many applications in our daily lives. Scientists have drawn inspiration from this phenomenon to invent many things, such as water purifiers. You may have water purifiers at home.
Scientists have studied frog skin and created similar membrane-like structures that allow water molecules and some minerals to pass through the membrane while filtering out harmful bacteria and viruses.
Now you know that frogs don't drink with their mouths; they absorb water with their bellies and thighs.
Finally, I'd like to ask you, have you ever seen a frog? Where did you see it? Please share your thoughts in the comments.
