Jellyfish can make their own light, like tiny glowing lanterns in the ocean. This helps them shine bright when they're swimming, startle enemies, or attract food, it’s like having a magical flashlight inside your body!
Examples
- A jellyfish turns on its light to startle a fish that is trying to eat it.
- When two jellyfish swim together, they glow in sync like a living dance party.
- A baby jellyfish uses its tiny flash of light to attract plankton for dinner.
