Phuket lifeguards have warned swimmers of Portuguese man-of-war, a type of poisonous jelly fish.
Lifeguards at local beaches told the Phuket Express on Wednesday (June 7th) that they had found many Portuguese man-of-war jelly fish on beaches in Phuket during the recent monsoon season.
If a swimmer has been stung, seawater and vinegar, if available, can be used to wash the affected skin and remove its tentacle. After that, use some hot water to cover the affected area for 20 minutes to relieve the pain.
Swimmers afraid of the potential of being stung should avoid entering the water at beaches with known jellyfish populations, said lifeguards. Swimmers should also be aware of flags on beaches and listen to instructions from lifeguards.
