OtterKnow Kids EncyclopediaJellyfish are soft, squishy animals that float in the ocean. They do not have a brain, bones, or a heart! Jellyfish have been living in the ocean for millions and millions of years.
Jellyfish have see-through, squishy bodies and long tentacles that hang down. They come in many shapes and sizes. Some jellyfish are as small as a peanut and some are bigger than a person!
Jellyfish move by squeezing their body like an opening and closing umbrella. They drift along with the ocean currents. Some jellyfish swim up and down, but most go wherever the water takes them.
- Some jellyfish can glow in the dark, which is really cool!
- A group of jellyfish is called a “smack.”
- Jellyfish are mostly made of water.
- Jellyfish have been around even longer than the dinosaurs!
