What species of jellyfish are there in Greece?

Greece has a diverse marine environment, and many species of jellyfish can be found in its waters. Here are some of the common ones:

Common Jellyfish:

* Barrel Jellyfish (Rhizostoma pulmo): This large, white jellyfish is very common in the Aegean Sea. It has a distinctive dome-shaped bell and thick, fleshy arms. It is generally not harmful to humans.

* Moon Jellyfish (Aurelia aurita): This translucent jellyfish is found worldwide, including the Mediterranean. It has four horseshoe-shaped gonads visible through its bell. It is not considered dangerous.

* Compass Jellyfish (Chrysaora hysoscella): This jellyfish has distinctive brown markings on its bell that resemble a compass. It has long, trailing tentacles and can deliver a painful sting.

Other Notable Species:

* Lion's Mane Jellyfish (Cyanea capillata): This is one of the largest jellyfish species, with a bell that can reach up to 6 feet in diameter. It has a distinctive mane of long tentacles. While rare in the Mediterranean, it has been spotted in the Aegean Sea.

* Portuguese Man-of-War (Physalia physalis): This is not actually a jellyfish but a colony of polyps. It has a distinctive blue, balloon-like float and long, stinging tentacles. It is rarely found in the Aegean but can occasionally be carried there by currents.

* Box Jellyfish (Chironex fleckeri): These highly dangerous jellyfish are found in the Indo-Pacific region and are not typically found in the Mediterranean.

Important Note: Jellyfish populations fluctuate depending on various factors, including water temperature, currents, and food availability. It's always a good idea to check with local authorities or marine experts for the latest information on jellyfish activity in specific areas.
