Why Jellyfish Are Made Up of Almost All Water: Explained for 5-Year-Olds

Learn in a fun and simple way why jellyfish are mostly water, perfect for young children aged 5 years old.

Hi there! Do you know what a jellyfish is? It's a strange and beautiful sea animal that looks like a squishy umbrella floating in the water.

Now, jellyfish are very special because they are made of almost all water. That means if you could weight a jellyfish, most of it would be water, just like the water you drink or swim in!

Here’s why:

  • Soft and squishy: Jellyfish don’t have hard bones inside them like we do. They are soft and squishy because they are mostly made of water.
  • Helps them float: Since they are filled with water, they can gently float and swim in the ocean. They move by pushing water around with their bell (the top part that looks like an umbrella).
  • Keeps them safe: Being soft and watery helps jellyfish hide in the ocean and not get hurt easily.

So, jellyfish are almost all water. That’s what makes them look like they are shining and glowing underwater!

Isn’t that cool?
