Have you ever seen a jellyfish glowing in the water? They look like magical creatures from a fairy tale! Today, we’re going to learn about these amazing animals and their relatives, called cnidarians.
Cnidarians are a group of animals that live in the ocean. They are divided into two main groups: jellyfish and polyp animals. Let’s explore each of them!
Jellyfish are fascinating creatures. They have bodies that are almost see-through and feel like jelly. If you look closely, they resemble an umbrella floating in the water. Jellyfish have a mouth and long, wiggly tentacles hanging down from their bodies. These tentacles have special stingers that help them catch food.
Some jellyfish swim around in the ocean, while others just drift along with the sea currents. They can be a bit lazy, letting the water carry them wherever it goes!
Polyp animals are another type of cnidarian. They like to live on reefs or attach themselves to rocks using their sticky suckers. Polyps have tentacles and a mouth too, but their mouth and tentacles are on the top of their bodies, unlike jellyfish.
Polyps use their tentacles to catch food, just like jellyfish do. They come in many different shapes and colors, making them look like beautiful underwater flowers!
Have you ever been stung by a jellyfish? If you see one while swimming, don’t worry! Just stay calm and swim away slowly. Jellyfish don’t want to hurt people; they only sting if you accidentally bump into them.
Remember, jellyfish are more afraid of you than you are of them. So, if you spot one, just give it some space and enjoy watching it from a distance.
If you enjoyed learning about cnidarians, there’s so much more to discover! You can explore more fun facts and stories about animals by trying out the Smile and Learn platform. It’s full of games, videos, and interactive stories that make learning exciting. You can use it on your mobile, tablet, or PC. Have fun exploring!
Jellyfish Movement Experiment: Create your own jellyfish model using a plastic bag and some string. Fill a clear bowl with water and gently place your jellyfish model inside. Watch how it moves and floats in the water. Can you make it move like a real jellyfish by gently swirling the water? Discuss with your friends or family how jellyfish move in the ocean and what helps them drift with the currents.
Polyp Observation Activity: Go on a nature walk or visit an aquarium to observe different types of polyps or similar creatures like sea anemones. Draw a picture of what you see and label the parts, such as the tentacles and mouth. Talk about how these animals might use their tentacles to catch food. How are they similar to or different from jellyfish?
Story Time with Cnidarians: Imagine you are a jellyfish or a polyp living in the ocean. Write a short story or draw a comic strip about a day in your life. What do you see around you? How do you catch your food? Share your story with your class or family and discuss what you learned about cnidarians.

I’ve fallen asleep; it’s so late. Time to go home. Wow, look at that fluorescent jellyfish! So cool! There are tons of them. I’ll try not to move much; I don’t want to get stung. Well, they’re swimming away, so I’m going to tell you all about the invertebrate group that jellyfish belong to.
Cnidarians! Have you ever heard of them? Cnidarians are marine animals divided into two groups: jellyfish and polyp animals. Jellyfish are almost transparent, and their bodies are gelatinous. They look like an umbrella. Their mouth and tentacles are in the lower part of their body. The tentacles have toxic substances that jellyfish use to capture their prey.
Some jellyfish swim in the water, while others are simply dragged by the sea currents. They’re so lazy!
Polyp animals form another group of cnidarians. They live on reefs or attach themselves to rocks using their suckers. Polyps also have tentacles and a mouth, which they use to feed themselves, but unlike jellyfish, their mouth and tentacles are in the upper part of their body.
Watch out! Cnidarians are really hungry today! As you can see, there are cnidarians of many sorts and colors. They really look so pretty!
Have you ever been stung by a jellyfish? If you ever see one in the sea, stay calm and swim away slowly. Jellyfish never attack people; they would only sting if you are in their way.
Look, there’s one over there! I’m swimming away slowly. So easy! That’s all about cnidarians. I’m going back to my swim. See you around!
