Do frogs drink water? (through their skin)

Water is a factor of life. Every planet that has water in space has the possibility of life there. You may not believe it, but living things depend more on the water than the air.

Like other living things, frogs also need water to live. Water is everything to frogs. We always see them sitting in water. But they never drink water through their mouths.

So how do they get the water they need? The answer to this question is their skin. Frogs absorb water through their skin. This is done by a process called osmosis.

Do frogs drink water from their skin?

how do frogs drink

Frogs, like other amphibians, have unique physical capabilities that help them meet their needs in unusual and special ways.

One of them is their skin. The skin of frogs is one of the most important parts of their body. Frogs breathe through their skin and absorb various substances, such as water.

The absorption of water by their skin is called dermal absorption. They have spots on their chest and thighs that absorb water from those areas. This action causes them to receive water directly. Frogs do not drink water but absorb it.

This capability can be dangerous because of their skin’s high absorption properties. Water may also introduce toxic and harmful substances into their bodies.

Their skin should always be moist, and being moist is what makes them breathe better. If the skin of frogs is dry, they will have difficulty breathing.

How do frogs drink water?

How frogs drink water

As we said, frogs depend on water and absorb water through their skin. Their skin has a type of membrane that allows water to pass through.

The absorption of water in frogs’ bodies is different from other animals. They take water indirectly. But other animals do it by drinking and entering the water into the stomach and digestion and absorption.

That means frogs can sit comfortably in the water and at the same time enter the water into their body. But this action may be dangerous for them because Their skin not only allows water to pass through it, but other substances can also pass through it. If the water is polluted, it means that the pollution will enter their body directly.

That is why most frogs live near fresh and clean water. The presence of water is vital for them. Also, their skin’s absorption power is very high, and frogs do not need liquid water to absorb; they can receive moisture from the air, soil, and even plants.

How does frogs’ skin absorb water?

Frog skin absorbs water through a process called osmosis. In this process, the thinner liquid absorbs the thicker liquid when two liquids are placed next to each other.

The frog’s body always has more salt than water. Therefore, the frog’s body fluids are thicker than water, and when water comes into contact with the frog’s skin, osmosis occurs, and the frog’s body absorbs it.

The frog’s skin is susceptible and can absorb the smallest water molecules. Some frogs supply most of their water from the morning fog and moisture in the air.

They can also absorb the minimum amount of moisture in the soil or the leaves and trunks of trees.

As much as their skin can absorb water very quickly and in large quantities, the opposite also happens. If the frog is exposed to heat and dryness, it will lose water fast and gets dry.

The importance of water for frogs

do frogs need water

The importance of water for frogs is very high. They need water to perform various activities in all stages of their lives. Water ensures their survival.

Almost all frog species cannot live without water, except for a few that are desert fricative, the ability to hold water in their bodies for a long time. So they will have problems without water too. Some of the importance of water for frogs are:

  • Breathing:

Breathing is one of the things that depend on the presence of water for frogs. Frogs absorb oxygen through their skin, just like the same process by which they absorb water into their body.

This process becomes difficult if their skin is dry. As frogs absorb water, they do the opposite on land and secrete mucus from their skin to keep it moist to improve their breathing.

Frogs also have lungs. They can drown. That is, if water enters their lungs, they will have problems. That’s why most of the time, Avoid submerging in water.

  • Reproduction:

Water plays an important role in the reproduction of frogs. Frogs lay their eggs in the water. Frogs’ eggs have a jelly coating from the beginning that protects the sperm; however, they are easily destroyed by heat and dryness. Also, frog eggs are very small at first, absorbing water and making them more prominent.

  • Heat regulation:

Frogs need water to regulate their body temperature. For this, they take out a lot of water from their body, and heat is also taken out of their body, and they cool down. But to do this, they need a water source. They need to be able to replace the lost water. For this, frogs always live near water holes and ponds. They also cool their bodies by sitting in water.

  • Before metamorphosis:

why frogs drink water

The life of frogs has two stages. After the first stage, they undergo metamorphosis, and their bodies are completed. Before metamorphosis, the frogs’ bodies are not completed. They do not have arms and legs and cannot live on land. They also have gills, and Their lungs are incomplete; therefore, they are aquatic in their first period of life and do not survive outside.

  • Body function:

Frogs need water for their body to function better. Like other amphibians, they have a high level of dehydration and are easily dehydrated, and their body must be moist at a high level.

This feature helps the body cells to remain active and healthy.

Water is very important for their skin because they produce mucus. And their skin needs water to produce mucus. Amphibians have several glands in their body. They even have more glands in their body than any other animal.

They have two types of glands. Mucous glands and granular glands. Mucous glands are responsible for secreting mucus that covers the surface of the frog’s skin and keeps water in their bodies.

Granular glands are also responsible for producing protein. Also, In poisonous frogs, the granular glands secrete a kind of poisonous substance to defend themselves from predators.

What water should I give my frog?

safe water for frogs

Frogs in captivity need special attention. You should always make water available to them. Give them as much clean water as a bowl, and it is recommended to clean their water container at least once a day.

To clean the frog’s water container, Do not use detergent or chemicals. The amount of water should be enough that the frog’s head is out of the water. The frog’s water should be clean and without chemicals.

Never give frogs tap water because it usually contains chlorine, which is very harmful to the frog. You can also use river water, rainwater, or distilled water. Put some plants, a little soil, and stones in the frog’s living area and keep them moist with a spray.

Also, if your frog becomes dehydrated, immediately place it in a water container so that the lower parts of its body are in the water. Ensure the frog’s eyes and mouth are out of the water. When the frog’s dehydration is resolved, give it a large amount of food because it will become weak.


Frogs need water like any other living thing. But they don’t drink water like humans. Frogs absorb the water through their skin.

They take water directly into their bodies. They do this through a process called osmosis. The skin of frogs has a high absorption power and absorbs substances other than water.

This makes them absorb harmful substances if the water is polluted. Also, frogs breathe through their skin. Frogs have lungs, and that’s why they can drown.

Frogs depend on water. They need water to breathe, and if their skin becomes dry, their breathing becomes difficult. Frogs also need water to reproduce and lay their eggs inside water.

They also need water to regulate their body temperature. Their skin has many glands that are responsible for protein production and mucus production. By secreting mucus on the skin, they keep their skin always moist and prevent water from leaving their bodies. Also, moisture keeps the cells of the frog’s body healthy.
