Common Species, Prevention, and First Aid

Cyprus, a jewel of the Eastern Mediterranean, is a popular destination for sun-seekers. Its crystal-clear waters are inviting, but travelers should be aware of the marine life that may be present. While jellyfish sightings are not a constant threat, they do occur, especially in the warmer months. Knowing how to identify the common species and what to do in case of a sting is crucial for a safe holiday.

Current Status: August 2025

As of August 2025, reports of jellyfish sightings in Cyprus are more frequent along the island's southern and eastern coasts. Popular tourist spots such as Ayia Napa, Protaras, and Larnaca have seen an increase in the number of jellyfish, most notably the Nomad Jellyfish (Rhopilema nomadica). Swimmers are advised to be cautious and pay attention to the purple flags that local authorities use to indicate a jellyfish warning. The western coast, including the popular beaches of Paphos, generally has fewer sightings.

Common Jellyfish Species in Cyprus

1. The Nomad Jellyfish (Rhopilema nomadica)

This large jellyfish is a non-native species that has become one of the most prominent concerns for swimmers in the Eastern Mediterranean. It can grow up to 10 kg in weight and swarm in large numbers, posing a risk to swimmers.

Sting Severity: Painful and can be serious for vulnerable individuals.
Appearance: A large, almost spherical bell with a bluish-white color, lacking marginal tentacles but with eight oral arms.
Season: Late spring to autumn, when water is warmest.

2. The Moon Jellyfish (Aurelia aurita)

A translucent and harmless jellyfish, the Moon Jellyfish is a common sight in Cypriot waters. It is easily identifiable and poses little to no threat to humans.

Sting Severity: Harmless.
Appearance: A clear, saucer-shaped bell with four distinct horseshoe-shaped reproductive organs visible through the top.
Season: Present year-round but more abundant in cooler months.

3. The Fried Egg Jellyfish (Cotylorhiza tuberculata)

This jellyfish is a native species to the Mediterranean and is completely harmless. Its unique appearance makes it easy to identify.

Sting Severity: Harmless.
Appearance: A flat, circular bell with a bright yellow center, resembling a fried egg.
Season: Late summer to early autumn.

Prevention and What to Do If You Get Stung

The best way to deal with jellyfish is to avoid them entirely.

Prevention Tips:

Check Local Warnings: Always look for warning signs or flags on beaches. Many organized beaches will have a flag system to alert swimmers to the presence of jellyfish.
Ask Locals: Lifeguards, hotel staff, and restaurant owners are excellent sources of information. Ask them about recent sightings before you enter the water.
Wear Protection: In areas known for jellyfish, consider wearing a rash guard, wetsuit, or a full-body swimsuit. This provides a simple but effective physical barrier.
Avoid Certain Times: Jellyfish often follow the sun and may be more visible in calm, shallow waters. Be especially cautious after a period of prolonged calm weather, as swarms can gather near the shore.

First Aid for a Sting:

If you are stung, stay calm and follow these steps:

Get Out of the Water: Exit the water immediately to prevent further stings.
Rinse the Area: Rinse the affected area with seawater. Do not use fresh water, as it can cause the remaining nematocysts to fire.
Apply a Neutralizer: If available, rinse the area with vinegar for at least 30 seconds. This is the most effective way to deactivate the stinging cells of most Mediterranean species, including the Mauve Stinger.
Remove Tentacles: Carefully and gently remove any remaining tentacles or stingers with tweezers. Do not use your bare hands.
Apply Heat: After rinsing and removing the tentacles, immerse the stung area in hot water (as hot as you can stand without burning) for 20-45 minutes. This helps to break down the venom and reduce pain. A hot pack or towel can also work.
Pain Relief: Over-the-counter pain relievers or antihistamines can help with pain and itching.
Seek Medical Help: If you experience severe symptoms like difficulty breathing, chest pain, swelling of the face or mouth, or if the pain is unbearable, seek immediate medical attention.
