Toxic Jellyfish Arriving Earlier and in Greater Numbers, Weighing Up to 150kg

Are toxic jellyfish appearing frequently at beaches these days, raising safety concerns?

Yes, driven by high water temperatures and strong currents, the appearance of toxic jellyfish has come about two weeks earlier than usual.

According to the National Institute of Fisheries Science, the emergence of the Nemopilema nomurai, a representative toxic jellyfish, has increased about fivefold this year compared to last year.

In addition, giant Nomura's jellyfish (or ghost jellyfish), reaching up to 2 meters in length and weighing 150 kg, have been increasingly spotted beyond Jeju to the coastal waters of South Jeolla, South Gyeongsang, and Busan, requiring special caution from vacationers visiting beaches during the holiday season.

If stung by a jellyfish, it is important to immediately get out of the water and rinse the affected area with seawater or saline solution.

Using tap water or alcohol can further stimulate the remaining stingers and worsen symptoms.

Experts noted that people are often stung by detached tentacles even without direct contact with the jellyfish, urging caution even at beaches equipped with protective nets.
