Now these nasty buggers are appearing in greater numbers and are moving north. Several have been found on beaches in Trat Province in the south east. Warming of the sea is the main reason why they have left their native waters off Australia. Claimed to be the most venomous marine creature known to mankind, their stings can quickly induce paralysis leading to death. Transparent and with its body pale blue in colour, each of its four corners has about 15 tentacles, each with up to 1,000 stinging cells. Last year two tourists died as a result of stings off Koh Samui.

The TAT and all Australian websites, including those of the Government and the Australian St. John’s Ambulance continue to recommend not touching the stings or dousing the affected area with anything other than vinegar as temporary first aid. Thereafter get the person to hospital as fast as possible.
Some researchers have questioned the use of vinegar but this goes against the vast majority of expert advice.

The research concluded that further research is required . . . It is currently concluded that there is insufficient evidence to start recommending that vinegar should not be used in box jellyfish stings.
