Deadly Marine Threat Warns Beachgoers at Popular Phuket Beaches

Tourists in Phuket, southern Thailand, received an unusual warning after dozens of poisonous Portuguese man-of-war washed up on several of the island’s most popular beaches. Phuket lifeguards said the creatures were found at Nai Harn, Kata Noi and Kata, all especially popular with Israeli travelers.

Authorities urged the public not to touch them, even if they appear dead or dry on the sand. Many people mistake them for jellyfish, but they are distinct marine animals with a translucent blue-purple float and long tentacles filled with potent venom. The tentacles can still inject venom after the animal has washed ashore.

The venom can cause severe pain, intense burning, swelling and serious allergic reactions. In some cases it can also affect the nervous system and heart function. Death is rare, but Thai officials said people with allergies or medical sensitivities face a higher risk.

Local authorities said the animals are common in tropical oceans and can be driven onto beaches by strong winds and currents. They advised swimmers to follow lifeguard instructions, avoid any unfamiliar sea creature on the shoreline, and seek immediate medical treatment if stung or exposed to venom. The warning comes during Thailand’s peak tourist season, when thousands of Israelis are expected to visit Phuket’s beaches in the coming summer months.
