PHUKET - Lifeguards are warning beachgoers that venomous Portuguese man-of-war jellyfish are washing up on three Phuket beaches and should be avoided.
The Phuket Lifeguard Service posted on its Facebook page that Portugese man-of-war were found on Nai Harn, Kata Noi and Kata beaches on Sunday.
Beachgoers should not touch them because their tentacles could still inject venom if touched, even after being washed ashore.
Their venom causes a burning pain and severe allergic reaction, affecting the nervous system and heart function, but is rarely lethal to humans.
