The Spanish coasts are already bordering on overbooking. With the arrival of the heat, the classic images of summer repeat themselves: crowded beaches, sunshades planted like flags, and thousands of tourists surrendering to the sun. But among so many summer postcards, a much less welcome visitor has burst in. It brings no suitcases or sunscreen, but stinging tentacles and a reputation that precedes it: The “Sea Carnation,” one of the most feared jellyfish in the Mediterranean, is already being seen close to the coast.
This species, also known as the luminous jellyfish, was sighted up to five times along the coast of Málaga from June 12 to 17, from Calahonda beach to Torre del Mar, according to records from the Medusapp application.
This jellyfish, whose scientific name is Pelagia noctiluca, is characterized by its bioluminescence ability, which allows it to emit bluish flashes of light when it feels threatened or during its movement. Its gelatinous and semi-transparent body measures between 3 and 12 centimeters in diameter and consists mainly of water, giving it a delicate and almost ethereal texture. It has long tentacles, up to several meters long, which it uses to catch its prey, mainly small fish and plankton, with the help of stinging cells, the nematocysts. Although its luminous beauty can be fascinating for bathers, it is important to emphasize that its sting can cause skin irritation, ranging from mild discomfort to allergic reactions in more sensitive people. Furthermore, “due to their long tentacles, they can cause bites from a great distance, so the sting is often received without seeing the offending specimen,” explains the Provincial Council of Málaga.
Why is it being seen more frequently? Its presence on the coast of Málaga during these June days could be related to ocean currents and the specific temperature and salinity conditions that favor its migration towards coastal waters. Although its appearance is not exceptional, the repetition of sightings in a short time and on several beaches can reflect a series of environmental factors resulting from climate change.
What to do if you are stung by this jellyfish? If you are confronted with a Pelagia noctiluca sting, the first thing to do is to calmly get out of the water to prevent the pain or reaction from worsening. It is important not to rub the affected area, as this can activate more stinging cells (the nematocysts). It is advisable to rinse the area with salt water, never with fresh water, as this can intensify the release of toxins. Applying cold compresses (no ice directly on the skin) is also helpful to relieve the pain. In some cases, vinegar can be used to neutralize the remains of tentacles, although this is not always indicated for this specific species. In any case, if symptoms persist, spread, or signs of an allergic reaction occur (such as difficulty breathing, swelling, or dizziness), it is essential to seek medical attention.
