Learn fun and simple facts about jellyfish, the ocean creatures that have lived since before dinosaurs, perfect for 7-year-olds.
Jellyfish are soft, squishy animals that live in the ocean. They look like floating umbrellas with long, wiggly arms called tentacles. Jellyfish don't have bones, a brain, or a heart!
Jellyfish have been around for a very, very long time – even before the dinosaurs! That means they are like the "grandpas" of the ocean because they are some of the oldest creatures in the sea.
Jellyfish move by pushing water out from their bodies, sort of like how you squirt water from a squishy toy. This helps them float and drift in the ocean currents.
Even though jellyfish don’t have brains, they can still sense things around them, like light and touch. They use their tentacles to catch tiny food to eat.
Isn’t it cool to know that jellyfish have been swimming in the oceans for hundreds of millions of years?
