Not technically a jellyfish, this colonial cnidarian moves by means of the pulsing bell-shaped individual on the bottom of the page. The "tentacles" are actually multiple individuals swollen with symbiotic algae resembling kelp or other seaweeds. Each has a single eye to warn it of approaching fish. When they see something coming, they contract, and feeling this, the large individual closes around them. It is very tough and slippery and can only be swallowed whole or not at all. This deters all but the largest fish. When the danger passes, it will open again to soak up sunlight and dissolved carbon dioxide from the water. Though belonging to the same phylum as jellyfish and fire coral, these creatures have no stinging cells and are completely harmless.
