Hello everyone! Today, we’re going to learn about one of the most fascinating animals in the ocean: the jellyfish. Are you ready to discover some incredible facts about jellyfish? Let’s dive in!
Jellyfish are sea creatures that belong to a group called Cnidaria. They don’t have bones, so they’re called invertebrates. Jellyfish are carnivores, which means they eat other animals like tiny plankton, fish eggs, and small sea creatures. They come in many sizes, and the biggest ones can be as long as 120 feet if you include their tentacles! But don’t worry, most jellyfish aren’t that big.
Jellyfish have a bell-shaped body that feels like jelly. Here’s a fun fact: more than 95% of their body is made of water! Isn’t that amazing?
Did you know that jellyfish are some of the oldest animals on Earth? They’ve been around for more than 500 million years, even before the dinosaurs! Although most jellyfish live for about six months, some can live longer because they can reproduce all by themselves.
There’s a special kind of jellyfish known as the “immortal jellyfish.” When it starts to get old, it can turn back into a young jellyfish and start its life all over again. How cool is that?
Jellyfish are quite unique because they don’t have a brain, heart, or blood. Instead, they have a simple system that helps them sense light and dark. Some jellyfish can even glow in the dark, which helps them scare away predators by showing that they might be dangerous.
Even though jellyfish are amazing, they have many predators. Animals like sea turtles, sharks, whales, and even some fish and crabs like to eat jellyfish. Poor jellyfish have to be careful!
There are about 2,000 different types of jellyfish, and you can find them in every ocean around the world. Some jellyfish even live in freshwater! Sometimes, ocean currents bring jellyfish to the shore, and this can be related to climate change because warmer water temperatures can move them closer to beaches.
Be careful around jellyfish because their tentacles have special cells that can sting you. While most jellyfish stings aren’t very dangerous, they can hurt a lot if you get stung.
Now you know some amazing things about jellyfish! Keep exploring and learning about the wonderful creatures in our oceans. See you next time!
Create Your Own Jellyfish: Gather some simple materials like paper plates, colored tissue paper, and string. Use the paper plate as the jellyfish’s bell-shaped body and the tissue paper and string to create tentacles. As you make your jellyfish, think about how jellyfish move in the water and how their tentacles help them catch food. Once finished, hang your jellyfish in your room and imagine it floating in the ocean!
Jellyfish Observation Journal: Next time you visit an aquarium or watch a nature documentary, pay close attention to the jellyfish. Write down or draw what you notice about how they move, what colors they are, and how they interact with other sea creatures. Do they glow in the dark? How do they use their tentacles? Share your observations with your family or friends and discuss what makes jellyfish unique.
Jellyfish and Climate Change Discussion: Talk with your family about how climate change might affect jellyfish and other sea creatures. Why do you think warmer water temperatures might bring jellyfish closer to beaches? How can we help protect the oceans and the animals that live there? Think of one small action you can take to help the environment, like reducing plastic use or conserving water, and try to do it every day.
Sure! Here’s a sanitized version of the YouTube transcript:

Hello everyone! Today, I’m going to talk to you about one of the most fascinating animals: the jellyfish. Do you want to know some incredible facts about jellyfish? Let’s go!
Jellyfish are invertebrate animals belonging to the Cnidaria group. They are carnivorous and feed on plankton, crustaceans, fish eggs, and larvae. They come in many sizes; the largest can weigh up to 7 ounces and measure up to 120 feet when including their tentacles, but they’re usually not that big—thank goodness!
Adult jellyfish are bell-shaped, their bodies are jelly-like, and they have long tentacles. Here’s a fun fact: more than 95% of their body is made up of water! Amazing, right?
Did you know that jellyfish are one of the oldest animals on planet Earth? They’ve been living here for more than 500 million years. The scientific community considers them the oldest animals in the world—older than the dinosaurs! Although they usually live for only about six months, some species are believed to have survived longer due to their ability to reproduce by themselves.
Interestingly, a type of immortal jellyfish has been discovered. This species, when it begins to age, reverts to a pre-maturation phase that allows it to start its life cycle again. How cool is that?
What if I told you that jellyfish have no blood? They also lack a brain, heart, or nervous system. Their senses are very basic and consist of a neural network that differentiates light and dark, and they use sensors to identify their prey. Some jellyfish even glow! This characteristic helps them defend themselves from predators by warning them that they are toxic.
Speaking of predators, jellyfish have many, including some fish, sea turtles, sharks, whales, and even crabs. Poor things—they have so many enemies!
There are about 2,000 different types of jellyfish, and we can find them in every ocean on the planet. Did you know that there are also freshwater jellyfish? How interesting! Although they live offshore, currents can wash them ashore. Unfortunately, their presence on beaches is closely related to climate change. The increase in water temperatures creates surface currents that bring jellyfish to shore.
Jellyfish tentacles are covered in cells that can sting you just by touching them. They’re not very dangerous, but if you’ve ever been stung, you know it can hurt a lot.
Well, you’ve already learned a few things about these interesting animals. See you soon!
