A jellyfish has no head, brain, heart, eyes, nor ears. It has no bones OR blood
either. It is 95% water!! Do you think that it's alive????
Movement:
Jellyfishes can't swim. They depend on the currents to transport them from
place to place. Some jellyfishes can tighten their bell and then make it bigger.
This pulsating lets them propel themselves upward through the water.
It's similar to letting a filled balloon empty itself.
Excretion:
A jellyfish has a simple digestive system.
It's eats using it's mouth and excrete using it's mouth too.
From this Picture, it shows that Jellyfishes DO reproduce... But only in a different way...
Conclusion: Jellyfishes are ALIVE!
