The presence of jellyfish in Mar del Plata is no longer an isolated phenomenon. This is due to the sustained increase in sea water temperature on the Atlantic coast. Lifeguards from Punta Mogotes in the city of Mar del Plata assured the Argentine News Agency that this is a usual phenomenon and that it “happens every summer at some point”. Warmer water favors the reproduction of these marine organisms and causes them to approach the coast in greater numbers. Specialists point out that summers with sea temperatures above average, as is the case this year in Mar del Plata, increase the probability of encounters with these gelatinous animals, especially on days with little wave action. Jellyfish, also known as sea nettles, do not attack: they are carried by currents and wind. However, they have tentacles with stinging cells that release toxins upon contact with the skin. A sting usually causes intense burning, redness, itching, and a burning sensation. In most cases, stings are not serious but are very annoying, especially for children and people with sensitive skin. In case of a jellyfish sting, lifeguards recommend getting out of the water immediately, not rubbing the affected area, washing it with seawater (never freshwater), applying vinegar if available, as it helps to neutralize the toxins. You can also apply a cold compress (ice wrapped in a cloth). In case of persistent pain, use a cream with corticosteroids or antihistamines, always under medical advice. If more severe symptoms appear, such as difficulty breathing, dizziness, or excessive swelling, you should immediately seek medical attention. It is difficult to completely avoid stings, but precautions can be taken: pay attention to lifeguard warnings, avoid swimming when jellyfish are seen in the water or on the shore, do not touch them, even if they appear dead, use UV shirts or wetsuits to reduce skin contact. Enter the sea carefully and avoid areas where the water is very calm.
