Jellyfish, venomous fish and snakes in Cyprus: what to know

Nomad jellyfish: when they appear and what helps

In March 2024 the Cyprus Department of Fisheries and Marine Research reported nomad jellyfish along the south and south-east coasts, mainly between Larnaca and Vasiliko, adding that they could appear elsewhere on the island too. The species comes from the Red Sea and entered the Mediterranean through the Suez Canal in the 1970s; mass occurrences have been recorded since the 1980s. Its hemispherical bell can reach a metre across, with eight thick arms hanging beneath it, and it is often milky to ice blue in colour. According to the department such an influx is temporary, usually lasting a few hours to a few days, and depends on currents, warm water and high nutrient levels.

The sting causes burning, itching, swelling and severe pain, which in serious cases can last for several weeks. Where jellyfish have been seen, the department asks people not to swim and not to touch them. After contact it advises keeping the affected part of the body still, removing any remaining tentacles with a plastic card, a piece of wood or tweezers, never with bare hands, and rinsing gently without rubbing; fresh water, alcohol, pressure, bandages, and creams or antihistamines without medical advice should be avoided. For rinsing, the department named vinegar as well as seawater in 2024. More recent studies advise against vinegar for this species: in a survey of 481 people stung in the eastern Mediterranean, vinegar was more often linked to no effect or a worsening, and the authors recommend rinsing off tentacle remains with seawater and avoiding vinegar (Regional Environmental Change, 2023). In laboratory tests on related scyphozoan jellyfish, vinegar actually triggered the stinging cells (International Journal of Environmental Research and Public Health, 2023), and the UK's NHS names only seawater for rinsing. So the rule here is: rinse with seawater, no fresh water, no vinegar. In the same survey, 69.2 per cent of cases were mild, 24.1 per cent moderate and 6.7 per cent severe. If the pain persists, see a doctor; people with allergies should go to a doctor or hospital straight away.

Venomous fish when swimming and snorkelling

In its booklet on toxic fish, the fisheries department describes several species that swimmers, snorkellers and anglers may meet along the Cypriot coast. The lionfish (Pterois miles) also came through the Suez Canal and has spread through coastal waters in recent years. It grows to 35 centimetres, has bold vertical stripes and long, hard fin spines carrying a potent venom. It is not aggressive, and most accidents involve fishermen handling their catch. A sting causes extreme pain, headache, vomiting, breathing difficulties and possibly allergic shock; small children, people with allergies and those with existing health conditions are at greater risk. It is edible all the same: according to a Cyprus Mail report from June 2026, the fisheries department actively promotes catching and eating it.

Weevers, at least four species of the family Trachinidae in Cyprus, usually measure 15 to 30 centimetres and lie well camouflaged in sand or mud with only the head showing. The venom sits in the spines of the first dorsal fin and in the spines on the gill covers; a sting causes pain, marked swelling, redness, fever, breathing difficulties and possibly allergic shock. Stingrays carry a sharp venomous spine near the base of their long tail. According to the department the pain lasts 6 to 48 hours and is worst in the first 30 to 60 minutes; depending on where and how deep the sting goes, it can lead to heart rhythm problems, low blood pressure, breathing difficulties and, in the worst case, cardiac arrest, so immediate medical care is essential. Scorpionfish and the introduced rabbitfish, which also take a baited hook, have venomous spines too.

For all of these stings the department's first measure is heat on the affected area, which limits the effect of the venom. The UK's NHS advises soaking the area for at least 30 minutes in very warm water, as hot as can be tolerated; test the temperature first with an uninjured hand so as not to scald yourself. After a lionfish or stingray sting, according to the department, you should get medical treatment as quickly as possible; after weever, scorpionfish or rabbitfish stings, if symptoms are severe.

The silver-cheeked toadfish: don't eat it, don't handle it

The silver-cheeked toadfish (Lagocephalus sceleratus) arrived through the Suez Canal and is now one of the most frequent bycatches of Cypriot fishermen, especially during its summer breeding season. It can reach 110 centimetres and 7 kilograms, has a greenish-brown back with evenly spaced black spots, a silver band from mouth to tail and four powerful teeth that together form a kind of beak. It uses them to bite fish off hooks and out of nets, damaging the gear.

Its tissues, above all the digestive tract, liver and gonads, contain the neurotoxin tetrodotoxin. Just a few milligrams can be fatal: according to the European Food Safety Authority (EFSA), a minimum lethal dose of 2 milligrams is often cited in the literature, and case reports describe acute poisoning from around 4 micrograms per kilogram of body weight. According to the fisheries department there is no antidote, and anyone poisoned must be taken to hospital immediately. Early signs are numbness of the lips and tongue, tingling in the face, hands and feet, headache, stomach pain, diarrhoea and nausea, followed by paralysis and breathing difficulties. The fish may not be sold in the EU. At least four other similar-looking pufferfish species in Cypriot waters are not considered toxic, but the department still advises against eating them.

A grant scheme shows how common the fish is: since June 2024, professional fishermen have been paid 4.73 euros per kilogram of silver-cheeked toadfish landed, and by June 2026 around 103 tonnes had been collected; according to the department there is no estimate of the total population (Cyprus Mail, 19.06.2026). If you fish yourself, the rules are in the guide to fishing in eastern Cyprus.

Snakes: only one species is truly dangerous

Cyprus has three venomous snake species: the cat snake (Telescopus fallax), the eastern Montpellier snake (Malpolon insignitus) and the blunt-nosed viper (Macrovipera lebetina). The first two are rear-fanged, and no cases of them envenoming people have been documented in Cyprus. The only medically important species is the blunt-nosed viper. It is found from the coastal lowlands up into the Troodos Mountains, often at the edges of fields and under shrubs, and mostly hibernates from November to March, although occasional bites occurred in the winter months too, an average of 0.14 cases a month in January.

An analysis of Ministry of Health hospital data shows how often it bites. Between 2013 and 2019, 288 people were admitted to public hospitals after a snakebite, an average of 41 a year. 92 per cent of cases fell between April and October, most of them in September. 84 per cent of patients went home within four days, and the average stay was 2.65 days. Between 2000 and 2019, two deaths were linked to snakebite. The picture varies by region: Paphos General Hospital treated more than half of all cases, Famagusta General Hospital 4 in seven years (Journal of Occupational Medicine and Toxicology, 2022).

The snake of Paralimni Lake near Sotira, the Cyprus grass snake (Natrix natrix cypriaca), is not one of the venomous species. BirdLife Cyprus describes it as a rare endemic subspecies and one of the lake's special features; there is more in the guide to Sotira.

Sea turtles: protect them, don't fear them

Sea turtles are harmless to people but need space. At the end of May 2026 the fisheries department announced the start of the nesting season, with the first nests already found. The two protected areas with their own rules are on the west and north-west coasts: Lara–Toxeftra and Polis–Gialia. At Lara–Toxeftra, staying on the beach at night, umbrellas, sunbeds and tents are among the things banned from 1 June to 30 September, as is fishing, except with a rod from the shore.

Across Cyprus, sea turtles must not be harassed or fed, nothing may disturb their natural behaviour, and nests and eggs are off limits. According to the department, only one or two hatchlings in a thousand survive long enough to return to the beach where they were born and breed.

Emergency number and hospital near Sotira

The general emergency number in Cyprus is 112 (Deputy Ministry of Tourism). The emergency department for the whole district is at Famagusta General Hospital in Paralimni (SHSO), around 5.7 road kilometres and about 11 minutes by car from Sotira according to our own OSRM route calculation. Night-duty pharmacies, doctors and the European Health Insurance Card are covered in the guide to everyday life in Sotira.

In everyday terms, by the sea and on land, that means: check for jellyfish before swimming, don't handle spiny fish with bare hands, never eat a pufferfish, and in summer don't reach blindly under shrubs.
