Contact with a jellyfish usually leaves burning red lines on the skin that trace the position of the tentacles. Leave the water and find the bagnino — beach lifeguard. On a supervised beach in Rimini, the lifeguard can help rinse the affected area and remove visible pieces of tentacle.
First aid for a jellyfish sting in Rimini
- Rinse the skin with seawater.
- Without rubbing, remove any remaining tentacles with a tool or a gloved hand.
- Immerse the affected area in water at 40–45 °C for 20–40 minutes.
- Note the time of contact and watch whether the swelling spreads.
- Call 112 or 118 for breathing difficulty, facial swelling or fainting.
Jellyfish found near Rimini and how painful their stings can be
Several Adriatic species affect the skin with differing intensity. The barrel jellyfish, fried egg jellyfish and moon jellyfish usually cause a mild local reaction, while contact with a mauve stinger or transparent box jellyfish can be painful.
Barrel jellyfish, or sea lung — Rhizostoma pulmo
Appearance: a large blue-white bell with a blue-purple rim and dense, folded oral arms rather than long, fine tentacles.
Size: usually one of the largest jellyfish in the Adriatic; the bell can reach approximately 50–60 cm.
Sting: mild. A sensitive person may experience itching and local irritation, but a severe sting is not typical of this species.

Fried egg jellyfish — Cotylorhiza tuberculata
Appearance: a rounded yellow centre resembling an egg yolk, with short branching appendages tipped in white and blue-purple beneath the bell.
Size: the bell is usually no more than 20–30 cm across.
Sting: barely noticeable for most people. Very sensitive skin may develop mild itching.

Moon jellyfish — Aurelia aurita
Appearance: a flat, transparent bell with four clearly visible pink or purple rings in the centre, resembling a four-leaf clover.
Size: the bell can reach approximately 30 cm across.
Sting: barely perceptible to most people.

Mauve stinger — Pelagia noctiluca
Appearance: a small pink, purple or brownish bell marked with conspicuous spots, with long, fine tentacles.
Size: the bell is usually about 8–10 cm across, but the tentacles are considerably longer.
Sting: strong. This is one of the more painfully stinging jellyfish in the Mediterranean and can leave vivid red lines, swelling and blisters.

Mediterranean box jellyfish — Carybdea marsupialis
Appearance: an almost transparent, cube-shaped bell with four fine tentacles. It is easy to miss in the water.
Size: the bell is approximately 3–4 cm, while the tentacles may extend to about 30 cm.
Sting: painful, though usually short-lived. Its small size does not imply a mild sting.

Of the species shown here, the mauve stinger and Mediterranean box jellyfish generally cause the most painful contact. A photograph cannot establish how severe the reaction is: the need for medical help depends on the area affected, the location of the sting and any general symptoms.
Why a jellyfish sting leaves red lines
Stinging cells are found on a jellyfish’s tentacles and around the edge of its body. On contact, they release toxin into the surface of the skin, so the mark often appears as a line or network of lines. These cells may remain active even on a jellyfish washed ashore.
Symptoms of a jellyfish sting
- sudden burning or pain;
- red lines or tentacle marks;
- itching, tingling and local swelling;
- sometimes blisters.
Tell the doctor or pharmacist how much skin was affected, where the sting is, when it happened, whether the swelling has changed and whether there are any general symptoms. It is especially important to mention asthma, severe allergies or previous anaphylaxis.
How long a jellyfish sting lasts
With a local reaction, the burning usually eases after the tentacles are removed and the area is warmed, while redness and itching may last for several days. The duration depends on the jellyfish species, the area of contact and the skin’s response. If the pain does not ease, the swelling continues to spread or large blisters develop, visit a pharmacy, medical centre or hospital emergency department.
When to call the emergency services after a jellyfish sting in Rimini
Call 112 for breathing difficulty, chest pain, swelling of the lips, tongue or throat, extensive swelling, repeated vomiting, seizures, sudden dizziness, fainting or rapid deterioration. A sting in the mouth, on the neck or near the eyes, or an extensive sting in a child, requires prompt medical assessment.
Call 112Treating a jellyfish sting on the beach
Use seawater for the initial rinse because fresh water may activate stinging cells left on the skin. Do not rub the area with sand or a towel. Use vinegar or another solution only if a local lifeguard or healthcare professional advises it; the appropriate treatment depends on the jellyfish species.
Where to seek help after a jellyfish sting in Rimini
For a small local reaction, you can visit a pharmacy and show the affected skin to the pharmacist. A sting near the eye or in the mouth, a large affected area in a child, increasing pain, fever or signs of inflammation requires a doctor’s assessment. Call 112 or 118 for breathing problems or fainting.
