Story Synopsis
Jellyfish look like drifting umbrellas, but they can move on purpose. This story explains how. Miluna shares that jellyfish have soft, flexible bodies. They move by pulsing: squeezing their bell to push water out, then relaxing to let water in. That push sends them gently forward. Currents can also carry them, so their movement often looks slow and peaceful. The tone stays dreamy and soothing, helping kids picture ocean life as calm and graceful. Curiosity stories like this connect science to gentle imagery that fits bedtime.

In One Glance
Jellyfish move using jet propulsion. By contracting the bell-shaped body, they expel water backward and create forward motion. When they relax, water flows back in and the cycle repeats. Because their bodies are soft and they often ride currents, their motion can look slow and drifting. The story presents this as a gentle rhythm and highlights how movement doesn’t require bones.
