''We have had reports of them being found on Patok beach, on Racha island,'' said Ukrit Sodbhumin, director of research at the Department of Marine and Coastal Resources.

''Every year the bluebottles arrive with the monsoon. What's different now is that there are more tourists on Phuket and around the region at this time of year.

''Caution is advised. We hope locals and lifeguards will keep an eye out for the bluebottles and warn tourists to avoid them.''

Treatment in the case of bluebottle stings was best with seawater, he said. Vinegar is recommended to treat the toxicity of all other jellyfish stings, which can go on destroying flesh if vinegar is not applied.
