I went for my morning swim in the Mar Menor this morning & for the second day running I saw one of these beauties. It is good to see them coming back to the Mar Menor as they will help clean up the algae problem. Contrary to popular belief they are harmless.
The jellyfish that I see whilst swimming in the Mar Menor is the Cotylorhiza Tuberculata. It is a species of jellyfish, also known as the Mediterranean jelly or fried egg jellyfish. It is commonly found in the Mediterranean Sea, Aegean Sea & Adriatic Sea. It can reach 35 cm in diameter but the ones I see swimming in the Mar Menor are no bigger than 10 cm in diameter. It seems that this jellyfish's sting has very little or no effect on humans.
This jellyfish belongs to the Order Rhizostomae, Family Cepheidae. One of the most common jellyfish in the Mediterranean sea & definitely the most colorful of all. Unlike many other jellyfish it is capable of autonomous movement without relying on the current.
