There are many different types of amphibians, but not all of them have gills. Gills are typically found on fish and some aquatic amphibians, like newts and salamanders. Frogs and toads do not have gills, but they can absorb oxygen through their skin.
When it comes to amphibians, it really depends on the species as to whether or not they have gills.

There are many different types of amphibians, and each has its own unique set of physical characteristics. While some amphibians have lungs and breathe air, others have gills and breathe water. So, which amphibians have gills?
One type of amphibian that has gills is the salamander. Salamanders live in both wet and dry habitats, but they must keep their skin moist in order to breathe. They typically have four legs and a long tail, and their bodies are covered in scales or smooth skin.
Some species of salamander also have external gills that they use for respiration.
Another type of amphibian with gills is the newt. Newts also live in both aquatic and terrestrial habitats, but they spend most of their time in water where they can breathe using their external gills.
Like salamanders, newts have four legs and a long tail, but their bodies are usually smooth instead of scaled.
Frogs are another common type of amphibian, but unlike salamanders and newts, frogs do not have gills. Instead, frogs absorb oxygen through their skin from the air around them.
Frogs typically have short limbs and no tails as adults (though some tadpoles do), and their skin is usually moist to help them breathe properly.
Do Amphibians Have Lungs And Gills?
Amphibians are a group of vertebrate animals that include frogs, toads, newts, and salamanders. These animals are unique in that they can live both on land and in water. In order to survive in both habitats, amphibians have developed specialized organs that allow them to breathe both air and water.
One of the most important organs for amphibians is their skin. This skin is permeable, meaning that it allows oxygen and other gases to pass through it. The skin also absorbs some water, which helps keep the animal moist.
This is important because amphibians need to be moist in order to breathe through their skin.
In addition to their permeable skin, amphibians also have lungs. However, these lungs are not as efficient as our own human lungs.
Amphibian lungs are filled with small sacs called alveoli, which help increase the surface area for gas exchange. However, because these alveoli are so small, they don’t exchange gases as efficiently as our larger human lungs do.
To make up for this efficiency difference, amphibians supplement their lung breathing with another method of respiration: buccal pumping.
Buccal pumping is a process where the animal pumps its throat muscles to move water over its gills. This allows the amphibian to extract oxygen from the water and get rid of carbon dioxide at the same time.
So while all amphibians have lungs, they also rely on their gills and skin to help them breathe properly in both air and water environments!
Do Amphibians Have Scales?
Most people think of amphibians as slimy, slippery creatures with smooth skin. But did you know that some amphibians actually have scales?
In fact, there are four main types of amphibian scales: granular, cycloid, ctenoid, and ganoid. Let’s take a closer look at each one! Granular scales are the most common type of scale found on amphibians.
They’re small and round, with a rough texture. These scales provide good protection from predators and parasites. Cycloid scales are similar to granular ones, but they’re larger and have a more smooth surface.
They’re often found on the backs and sides of frogs and toads. Ctenoid scales are another type of scale found on some amphibians. They’re usually oval-shaped with ridges running down the middle.
These ridges help the animal move through water more easily. Finally, ganoid scales are the largest and most protective type of scale found on amphibians. They’re bony plates that overlap each other like shingles on a roof.
Ganoid scales offer great defense against predators and harsh environments.
Can Amphibians Breathe Underwater?
Yes, amphibians can breathe underwater. They have special organs called gills that allow them to extract oxygen from the water. Amphibians typically live in or near water and use their gills to respire throughout their lives.
Some species of amphibians, such as certain frogs, can also absorb oxygen through their skin.
Amphibians Body Covering
Amphibians have a wide variety of body coverings, from the smooth skin of frogs to the scaly skin of salamanders. Each type of amphibian has a different type of skin, which helps them to survive in their specific environment.
Frogs have smooth, moist skin that is covered in mucus.
This mucus helps to keep the frog’s body wet and protects it from predators and parasites. The color of a frog’s skin can help it to blend in with its surroundings and make it difficult for predators to spot. Some frogs also have poison glands in their skin, which can deter predators or help the frog to catch prey.
Salamanders generally have dry, scaly skin that is covered in toxins. These toxins can deter predators or help the salamander to catch prey. Salamanders come in a wide variety of colors and patterns, which can help them to blend in with their surroundings and make it difficult for predators to spot them.
Some salamanders also have bright colors that warn predators that they are poisonous.
Toads have dry, bumpy skin that is covered in toxins. These toxins can deter predators or help the toad to catch prey.
Toads come in a variety of colors, but they are often brown or gray so that they can blend in with their surroundings.
How Do Amphibians Breathe on Land And in Water?
Amphibians are a class of vertebrate animals that include frogs, toads, newts, and salamanders. They are unique in that they can breathe both on land and in water. How do they do this?
The secret to amphibian respiration is their skin. Unlike our own skin, which is mostly waterproof, amphibian skin is semi-permeable. This means that it allows oxygen to pass through it and into the blood stream.
At the same time, it also allows carbon dioxide and other waste products to escape.
This type of respiration is called cutaneous respiration and it’s how most amphibians breathe when they are on land. When they are in water, however, they use a different method called buccal pumping.
This involves using their mouths and throats to draw water in and then force it out over their gills. The gills extract the oxygen from the water so that the amphibian can continue to breathe while submerged.
So there you have it – two ways that amphibians can breathe both on land and in water!

What Amphibians Keep Their Gills?
Amphibians are a class of vertebrates that include frogs, toads, newts, and salamanders. They are ectothermic animals, meaning they rely on the environment to regulate their body temperature. Amphibians typically have four legs and smooth, moist skin.
Many amphibians also have the ability to breathe through their skin.
One common characteristic of amphibians is that they go through metamorphosis during their lifetime. This means that they start out as larva with gills and tails before transforming into adults with lungs and four legs.
Some species of amphibian will keep their gills throughout their lives however, such as certain types of newts.
What Amphibians Have Gills And Lungs?
There are three main groups of amphibians: frogs and toads, salamanders, and caecilians. All three groups have members that have both gills and lungs.
Frogs and toads are the most familiar group of amphibians to most people.
They generally have short, stocky bodies, webbed feet, and long tongues. Many species of frog can inflate their bodies with air to make themselves look bigger and more intimidating to predators. Toads tend to be dryer and rougher skinned than frogs.
Some common examples of frogs with both gills and lungs are the African bullfrog, the American green treefrog, and the European fire-bellied toad. All three of these species start out their lives with external gills that they use for respiration in water. As they develop into adults, they develop internal lungs and lose their gills.
They still need moist skin in order to absorb oxygen though, so many species will remain near water sources even after they’ve lost their gills.
Salamanders are another group of amphibians that have both gills and lungs as adults. They’re typically slenderbodied with long tails (though there are some exceptions).
Salamanders can range greatly in size from a few centimeters to over a meter long! Most salamanders live on land but return to water to breed where their larvae hatch and grow into adulthood using external gills just like frogs do. After metamorphosis is complete however, they move onto land where they hunt for food using sight rather than relying on tongue flicks like many frogs do.
Salamanders that stay permanently aquatic usually retain their external gills as adults while those that don’t often lose them or keep only vestigial remnants depending on the species in question. The axolotl is a well-known example of a salamander that retains its external gills into adulthood while other notable examples include newts (like the alpine newt)and sirens (a type of aquatic salamander found in North America).
The last main group of amphibians -caecilians- are easily distinguished from other amphibians by their lack of limbs which makes them resemble giant worms instead!
Caecilians also burrow underground where they find most of their food through touch rather than sight since it’s typically quite dark underground where they live .
Do Frogs Have Gills?
Frogs have gills when they are tadpoles. Once they reach adulthood, frogs have lungs and no longer need gills.
Conclusion
There are three main types of amphibians- those that have lungs and breathe air, those that have gills and breathe water, and those that have a combination of both. The most common type of amphibian is the one with lungs, but there are some species that have gills instead. These include certain newts, salamanders, and frogs.
Gilled amphibians typically live their lives in water, only coming onto land to mate or lay eggs. They have specialised organs called external gills which extract oxygen from the water and allow them to breath underwater. These gills are often hidden away under flaps of skin known as opercula.
Some amphibians, such as the axolotl, can regenerate lost body parts including their spinal cord, heart, brain, eyes, limbs- even parts of their internal organs!
