“Bluebottles” washed up: jellyfish alarm on Phuket

Dozens of poisonous "bluebottles" washed up on the well-known Patong Beach on Thailand's vacation island of Phuket at the weekend. So far, however, no tourists have been stung.

As reported by the Bangkok Post newspaper, citing the local marine research center, officials and lifeguards have discovered around 40 specimens.

The jellyfish, whose scientific name is Physalia utriculus, belong to the same genus as the notorious Portuguese man o' war. However, "bluebottles" are smaller and less dangerous. Their shimmering bluish gas bubble, which is responsible for buoyancy, measures up to 15 centimetres. The tentacles can reach a length of ten meters.

Severe pain possible
These are not real jellyfish, but huge polyp colonies in which each individual performs a specific task. Anyone who comes into contact with the tentacles suffers severe pain and red welts on their skin. For humans, however, an encounter with the cnidarian is rarely fatal - except in the case of allergic shock.

Warning brochures distributed
The authorities distributed warning leaflets to the public and urged swimmers to take extra care to avoid stings. Lifeguards were on hand to provide first aid in the event of an emergency.
