ClassX Video Lessons Amphibians for Kids | What is an amphibian? Learn the characteristics of amphibians
Have you ever sorted your toys or clothes into different groups? Scientists do something similar with animals! They group animals based on their characteristics. One special group of animals is called amphibians. The word “amphibian” comes from a Greek word that means “double life” because these animals can live both on land and in water!
Can you think of any animals that are green and sometimes slimy? If you thought of frogs, toads, salamanders, or newts, you’re right! These are all amphibians. There are about 7,000 different kinds of amphibians in the world. Some frogs you might know are the American bullfrog and the poison dart frog. There are also many types of toads, like the American toad and the tomato toad.
Sometimes it’s hard to tell frogs and toads apart. Here’s a tip: frogs usually have smooth, moist skin and long legs for jumping. Toads have dry, bumpy skin and shorter legs because they walk more than they jump.
Amphibians have some cool features! They have backbones, just like us, but theirs are much smaller. They are cold-blooded, which means their body temperature changes with the temperature around them. If it’s warm outside, they are warm; if it’s cold, they are cold too.
Amphibians start their life in water. They hatch from soft, jelly-like eggs and look like tiny fish with tails and gills. As they grow, they go through a change called metamorphosis. They develop legs and lungs, allowing them to live on land. Frogs and toads lose their tails as adults, but salamanders and newts keep theirs.
Did you know that some salamanders can regrow lost limbs? And there’s a type of amphibian called caecilians that look like worms or snakes. They don’t have arms or legs and use their noses to dig through mud.
Amphibians can be found in many places like streams, forests, ponds, and swamps. They love damp or wet areas. They eat insects like spiders, beetles, and worms. Some frogs have long, sticky tongues to catch flies and moths.
Amphibians can be tiny or huge! The goliath frog can grow up to 15 inches long, while the smallest frog is only about a third of an inch. The Chinese giant salamander can be six feet long and weigh 140 pounds!
Amphibians are amazing creatures with lots of interesting facts. Next time you’re near water, see if you can spot any amphibians. There’s so much more to learn about these fascinating animals!

Amphibian Habitat Hunt: Take a walk in your backyard, a local park, or near a pond with an adult. Look for places where amphibians might live, like damp areas or near water. Draw a picture of the habitat you find and imagine what kind of amphibians might live there. Think about what they would eat and where they would hide.
Amphibian Life Cycle Craft: Create a simple craft to show the life cycle of a frog. Use paper plates to represent each stage: egg, tadpole, froglet, and adult frog. Draw or cut out pictures for each stage and glue them onto the plates. Arrange them in order and use string to connect them, showing how a frog changes as it grows.
Frog vs. Toad Observation: If you have a chance to see a frog or a toad, observe it carefully. Use a notebook to jot down its features. Is its skin smooth or bumpy? Are its legs long or short? Try to identify whether it’s a frog or a toad based on what you’ve learned. Share your findings with your class or family.

Amphibians! Have you ever sorted some of your things into different groups? Maybe you sort clothes by color or style, or your video games by category. Scientists do the same thing with animals and other objects. All animals, including humans, have a few things in common: they are living organisms, they need food and energy to survive, move, and grow, and they reproduce, which means they have offspring.
Though they have a lot in common, there are also many differences between animals. For example, when you see an insect like a mosquito or a butterfly, you know that it’s different from a fish. You also know that a cougar is different from a snake. Because of these differences, all animals are classified into special groups. Some of these groups include mammals (animals with hair), reptiles (creatures with dry, scaly skin), birds (which have feathers and wings), and fish (which have gills and live in water).
Other classifications include warm-blooded versus cold-blooded, vertebrates versus invertebrates, and living on land versus living in water. Humans live on land, even though we can swim, take showers, and jump into the ocean. We cannot live and survive in the water because we need oxygen to breathe. Fish are the opposite; they cannot live on land and can only survive in water.
Did you know that there is one group of animals that can live both on land and in water? This group is called amphibians. In fact, the Greek word for amphibian means “double life” or “two lives.” There are about 7,000 species of amphibians living in the world today that can survive in both environments.
You might be familiar with some amphibians. Can you think of any? Here’s a hint: think of animals that are green and often slimy. Did you think of toads, salamanders, newts, or frogs? If you did, you’re right!
You probably already know some things about frogs and toads, but did you know that there are many different types of both? Have you heard of the American bullfrog or the poison dart frog? What about the American toad or the tomato toad? There are around 2,000 different species of toads and frogs in our world, which makes you wonder where they all are hiding.
Sometimes it’s easy to mix up a frog and a toad. Here’s how you can tell them apart: as adults, frogs have smooth, moist skin and longer legs than toads, while toads have dry, bumpy skin and shorter legs because they walk more often than they jump.
Even though toads and frogs are different, they are both amphibians because they share some common characteristics. So, what makes an animal fit into the amphibian category? It’s simple: they each have characteristics that are the same, like webbed feet. They also have backbones, called vertebrates, just like you do, but their backbones are much smaller than humans.
Every group of animals has certain characteristics in common. Some of those characteristics are included in other groups too, like humans and amphibians both having vertebrates. However, because humans are warm-blooded and amphibians are cold-blooded, they cannot be in the same group, even though they share some traits.
Cold-blooded means that an amphibian’s body temperature changes based on the temperature of the air or water where they live. For example, if it’s 60 degrees, then their bodies adapt to that temperature. If it’s 40 degrees, they adapt to that temperature too. This is different from being warm-blooded. Humans maintain a constant body temperature of around 98.6 degrees, only changing when we are sick.
Another trait of amphibians is that part of their life is spent on land while the other part is spent in water. They can breathe using gills while in the water, just like fish. However, unlike fish, they later grow lungs and legs, which help them live on land.
Another interesting aspect of amphibians is their skin. While slimy might seem unappealing to us, it’s a very important part of being an amphibian. Adult amphibians must stay near water to keep their skin wet. An interesting fact about amphibians is that they don’t drink water; it is absorbed through their skin. Did you know that frogs can’t live in saltwater? The salt could potentially harm them and dehydrate them since their skin needs to stay moist.
All amphibians come from soft eggs that look like jelly. They go through a process called metamorphosis, which means they change into something else over time. When amphibians are newly born, they look like fish with tails and gills. After a while, they become tadpoles with two legs. The tadpoles change again and develop two more legs as well as a tail, looking like a small version of a frog, but with a tail. Finally, they become fully grown frogs.
While all amphibians have common characteristics, frogs and toads lose their tails when they reach adulthood, while salamanders and newts keep their tails. Salamanders and newts look like lizards without scales. A cool fact about newts and salamanders is that if they lose a limb, it will regenerate, meaning it will grow back.
Another species of amphibian is called caecilians. Caecilians do not have arms or legs; they use their pointed noses and strong skulls to burrow through mud. They look like worms or snakes, and some can grow to be over 4 feet long.
Amphibians live in a wide range of habitats, including streams, forests, meadows, ponds, lakes, swamps, and other damp or wet areas. Their diet includes spiders, beetles, and worms. Some frogs have long, sticky tongues that they flick to catch flies, moths, and other insects.
Amphibians come in all sizes too! The goliath frog can grow to be 15 inches long and weigh 8 pounds, while the smallest frog in the world is only about a third of an inch long. On the other hand, the Chinese giant salamander can be six feet long and weigh 140 pounds.
Can you imagine seeing that in a swamp? Amphibians are fascinating animals with many interesting facts. Did you know that some salamanders keep their gills and that frogs swallow their food whole? There’s much more to learn about these incredible creatures, so don’t stop here! The next time you are near some water, see if you can spot some amphibians.
