Similan Islands National Park in Phang Nga has temporarily closed a swimming area after officials detected blue button jellyfish along the shoreline. The park announced on February 22 that the jellyfish, known as Porpita Porpita, were primarily sighted along the eastern beach of Ko Si. The jellyfish can cause skin irritation, prompting the closure to ensure visitor safety.

The brightly colored Blue Button jellyfish have a central disc with numerous tentacles and are often carried ashore by ocean currents. Their sting, although less severe than that of a box jellyfish, can result in a burning sensation and symptoms such as redness, swelling, itching, or blisters. Even after washing up on the beach, the jellyfish can still irritate the skin, leading park officials to caution visitors against direct contact.

The park issued first-aid guidance for those who encounter the jellyfish. It is recommended to rinse the affected area with seawater, avoiding fresh water initially, and to carefully remove any tentacle fragments without rubbing. Severe reactions require immediate notification to park staff, who are prepared to assist.

In response to the jellyfish presence, the swimming zone on the eastern side of Ko Si has been closed until conditions are deemed safe again. Visitors are urged to report any jellyfish sightings to park officials and adhere to safety instructions. This precaution aims to prevent any adverse incidents and prioritize visitor welfare.

Looking ahead, the park will continue to monitor the situation closely. The swimming area will remain closed until the jellyfish are no longer perceived as a threat, ensuring a safe environment for tourists. Park officials are prepared to act promptly on new reports and provide updates as needed, reported The Thaiger.

The ‘blue bottle’ familiar to Australians, and known elsewhere as the ‘Portuguese man o’ war (actually a siphonophore rather than a jellyfish, and also a colony of organisms) is a different species, Physalia physalis.
