Cotylorhiza tuberculata (Mediterranean Jellyfish/Fried-egg Jellyfish)​

Commonly found in the Mediterranean, Adriatic, and Aegean Seas. Yellowish-brown algae co-living in the center of the bell of jellyfish, with purple pigment at the tip of oral arms. Occasionally some tiny animals like crabs would hide inside the jellyfish's bell, or hitching on the top of the bell.


The stings of Mediterranean jellyfish have very little effect on human.
