Warning issued after toxic fire jellyfish detected in Phuket waters

A public warning was issued on March 30 after toxic fire jellyfish were detected in high concentrations near Koh Aeo, Phuket. Deputy Prime Minister and Natural Resources and Environment Minister Suchart Chomklin said the Department of Marine and Coastal Resources (DMCR) found about 100 poisonous jellyfish per square metre floating at depths of 3 to 5 metres. Residents, tourists, and marine operators in southern and eastern Phuket have been urged to avoid direct contact during water activities.

Survey Details and Health Risks

The Upper Andaman Marine and Coastal Resources Research Centre identified the jellyfish as belonging to the genus Pelagia, with an average bell size of 2 to 3 centimetres. Calm sea conditions were noted at the time of the survey, which may have contributed to the high density of jellyfish near the surface.

Contact with these jellyfish can cause stinging pain, burning sensations, skin irritation, or a red rash, DMCR director-general Pinsak Suraswadi said. The DMCR advises pouring vinegar over stings for at least 30 seconds and seeking prompt medical attention.

Related Closures and Additional Jellyfish Sightings

A temporary swimming ban was imposed in parts of Similan Islands National Park, Phang Nga, after blue button jellyfish, known scientifically as Porpita porpita, were found along the shoreline. Park officials described the blue button as having a bright blue disc and numerous tentacles.

While blue button stings are less severe than those from box jellyfish, they can still cause immediate burning, swelling, itching, or clear blisters. The affected swimming zone remains closed as a precaution.
