Poisonous Nomad Jellyfish Appear on Cyprus Beaches: What to Do if Stung

The Department of Fisheries and Marine Research (TATHE) of the Ministry of Agriculture, Rural Development, and Environment of the Republic of Cyprus announced the appearance of dangerous jellyfish of the species Rhopilema nomadica, also known as nomads, on the country's beaches. They are mainly found between the areas of Larnaca and Vasilikos.

According to the agency's statement, the nomad jellyfish has a semi-spherical body up to 1 m in diameter. Eight thick tentacles grow from the central point of the body, which release a tiny "stinger" upon contact with a foreign object, carrying venom. The color of nomad jellyfish often ranges from milky to icy blue. This particular species is endemic to the Red Sea and first entered the Mediterranean Sea through the Suez Canal in the 1970s.

The presence and increase in the population of jellyfish are temporary phenomena, usually lasting from several hours to several days and are mainly due to the direction of ocean currents, favorable climatic conditions such as increased temperature and nutrient content. It is noted that the phenomenon is likely to be observed in other areas of Cyprus.

This species, Rhopilema nomadica, can cause a very painful sting in humans, as contact with the tentacles causes irritation, a burning sensation, itching, skin swelling, and intense pain. In severe cases, symptoms can last for several weeks. The public is asked to be especially cautious and avoid swimming in areas where this phenomenon is observed, as well as avoid touching the jellyfish.

What to do if stung by a jellyfish:

1. Immobilize the affected part of the body to prevent further spread of the tentacles.
2. Remove any remaining tentacles with a plastic card, piece of wood, or tweezers. Never do this with bare hands, as the tentacles will stick to the skin and transmit irritation.
3. Thoroughly rinse with seawater or vinegar, but do not rub the affected area. Do not use fresh water.
4. Avoid self-treatment: rinsing the wound with fresh water or alcohol, applying pressure or bandages, using creams or antihistamines without consulting a doctor.
5. If pain and discomfort persist, seek medical attention.
6. If a person has an allergy, they should seek medical attention or go to the hospital immediately.
