- No bones, brain, or heart
- Body is ~95–98% water

- Diet: Feed on plankton, small fish, and other tiny organisms
- Lifespan: Most live a few months to a year; some species can revert to earlier life stages and potentially live longer
Interesting Features
- Movement: Mostly drift with currents; can pulsate to move.
- Stings: Some species (like box jellyfish) have potent venom; others are harmless.
- Glow: Certain species are bioluminescent, creating a glowing effect in dark waters.
Human Uses
- Food: In parts of Asia, jellyfish are eaten in salads or preserved dishes.
- Research: Bioluminescent proteins from jellyfish are used in scientific research.
- Aquariums & Tourism: Popular in exhibits due to their mesmerizing movement.
Safety Notes
- Handling: Avoid touching wild jellyfish; some can sting dangerously.
- Eating: Only consume jellyfish that are properly processed and prepared for food.
