Box Jellyfish found in Phuket waters

They’re here! Box Jellyfish found in Phuket waters

After my recent article about the Thai government becoming more involved for research into box jelly fish in Thai waters, a new development occurred in Phuket. The Phuket Gazette reported on Monday, 27th october the article below in which is described how almost 40 box jellyfish got trapped around Phuket waters.
My first encounter with them was back in 2003! The blog post describing that encounter, is by far the most read post on my blog, it also reviews a story that happened to a very young boy, aged 4, who was stung by a box jelly fish in Thai waters in Koh Mak, south of Koh Chang in December 2007.

All in all an interesting development and there seems to be a growing awareness about the fact that box jellyfish actually are present in Thai waters, how unpleasant this may be. Recently I purchased a full body half millimeter suit which I use during my beach dives on Chaweng reef!

Here's the Phuket gazette article;

PANWA: The Phuket Marine Biological Center (PMBC) has issued an official warning following the collection of almost 40 box jellyfish in a trap in shallow waters off Ao Nambor, on Phuket’s east coast.

Some 38 of the jellyfish, which favor shallow brackish water, were recovered from a fish trap in a mangrove area on July 30. Eighteen more were found in the same area over a two-day collection period starting on October 20.

The search for the deadly jellyfish followed the reported death of a Swedish tourist off Koh Lanta, where another person was reported stung on April 3 this year.

A two-hour search using a seine off Koh Lanta on August 22 recovered 13 specimens, six of the multi-tentacled Chirodropidae family and seven of the smaller, single-tentacled Carybdeidae family.

The PMBC began their search for the jellyfish in Phuket in early July, working jointly with members of the the Disease Control Department’s Epidemiology Office.

The researchers have also questioned staff at four hospitals along the Andaman Coast to learn the incidence and type of jellyfish stings that heave been reported there.

Somchai Bussarawit, Chief of Reference Collection at the PMBC’s Phuket Aquarium, is working with the Central Marine Fisheries Research Institute in Australia to identify the collected specimens.

Of seven specimens collected at Ao Nambor that have already been sent to the institute, one has been confirmed as a Chirosoides buitendijkl, one of the seven members of the Chirodropidae family, he said.

The PMBC is preparing to send six more specimens which are thought possibly to be of the Carybdeidae family, he said.

The PMBC researcher, who expressed surprise at the discovery of these box jellies in local waters, said searches will now be conducted monthly.

Noting that he is not an expert in jellyfish, he said it was still unsure what threat the collected species found at Ao Nambor posed to people.

Although there have been no reports of box jellyfish stings in Phuket waters, the PMBC has issued a warning advising the public on what measures to take if they are stung.

Although not all box jellyfish are dangerous to humans, stings from the most venomous varieties can cause death within four minutes if the venom reaches the heart and causes cardiac arrest.

Any person who has suffered a possible box jellyfish sting should get out of the water as soon as possible, have his or her pulse rate monitored, and undergo cardiopulmonary resuscitation (CPR) in the event of heart failure.

The site of a sting should immediately be treated with vinegar to stop further injection of the toxin, the PMBC advises.

Do not rub or scratch the site of the sting or apply fresh water or alcohol to it, the PMBC advises.

Mr Somchai reiterated that there have been no box jellyfish sitings on west coast beaches, where the seawater is generally too saline an environment for box jellies.

However, he advises seaside resorts in all parts of the island to keep bottles of vinegar as a standard part of their first aid kits as it is effective in healing stings from other kinds of less venomous jellyfish.

Phuketwan.com has the most thorough and accurate coverage of the discovery of box jellyfish in the region. The reporters actually went with scientists on a jellyfish hunt. For anyone swimming in the Andaman, the articles on that site are well worth checking out. They broke the news of the presence of box jellyfish about 10 days before the Gazette.

Hello Camille,
Do you know something about stinger nets (like Australian's) working in that area?

Hi Bruno,

Unfortunately I never heard of stinger nets in Thailand, so far.
