Similan Islands (Ko Si Beach) – Blue Button Jelly Fish
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.
