Jellyfish stings are a common occurrence for beachgoers, but understanding how they work and how to treat them can make all the difference. So, why do jellyfish sting, and what exactly happens when they do?

Jellyfish stings are primarily a defense mechanism. When a jellyfish feels threatened or comes into contact with a potential predator or prey, it releases tiny barbed threads called nematocysts from specialized cells called cnidocytes located on its tentacles. These nematocysts contain venom that immobilizes or kills the target. Upon contact with the skin, the nematocysts discharge their venom, causing the characteristic burning sensation associated with jellyfish stings.

The mechanism of a jellyfish sting involves several steps. First, upon contact with the skin, the nematocysts deploy their harpoon-like structures, injecting venom into the victim. This venom contains a mixture of proteins and toxins that disrupt cellular function, leading to pain, inflammation, and in severe cases, systemic symptoms such as nausea, vomiting, and difficulty breathing. The severity of the sting depends on factors such as the species of jellyfish, the amount of venom injected, and the individual's sensitivity to the venom.

Jellyfish primarily use their tentacles to deliver their stings. These tentacles are covered with thousands of nematocysts, making them efficient weapons for capturing prey and deterring predators. When a jellyfish comes into contact with a human or other potential threat, it releases its tentacles, allowing the nematocysts to discharge their venom upon contact.

Despite popular belief, many myths surround the treatment of jellyfish stings. For example, while it was once thought that applying urine or rubbing alcohol could alleviate the pain of a jellyfish sting, these substances can trigger the discharge of more venom, worsening the symptoms. Similarly, applying fresh water or ice can also exacerbate the sting by causing the nematocysts to release more venom. Instead, the recommended treatment for jellyfish stings is to rinse the affected area with vinegar, which helps neutralize the venom and prevent further discharge of nematocysts. After applying vinegar, it's essential to carefully remove any remaining tentacles or nematocysts from the skin by gently scraping them off with a credit card or the edge of a blunt object. Once the tentacles are removed, the affected area can be soaked in hot water (not scalding) to alleviate pain and reduce swelling.

In conclusion, understanding the mechanism of jellyfish stings and knowing how to treat them effectively can help mitigate their effects and prevent complications. By debunking common myths and following proper first aid protocols, beachgoers can enjoy their time in the water safely and confidently. So, the next time you encounter a jellyfish, remember to reach for the vinegar, not the urine!
