Where to find box jellyfish

Survivors can experience considerable pain for weeks and often have significant scarring where the tentacles made contact. Box jellies, also called sea wasps and marine stingers, live primarily in coastal waters off Northern Australia and throughout the Indo-Pacific. They are pale blue and transparent in color and get their name from the cube-like shape of their bell. Up to 15 tentacles grow from each corner of the bell and can reach 10 feet in length.

Each tentacle has about 5, stinging cells, which are triggered not by touch but by the presence of a chemical on the outer layer of its prey. Box jellies are highly advanced among jellyfish.

They have developed the ability to move rather than just drift, jetting at up to four knots through the water. They also have eyes grouped in clusters of six on the four sides of their bell.

Welfare et al. There were no animal or human subjects. These press release claims have not been supported by any other investigators and have been completely rejected by the entire scientific community.

The study design and statistical validity has been criticized by Yanagihara and Chen [ 22 ]. Winkel K director of the Australian Venom Research Unit, the University of Melbourne expressed that there was not enough evidence to support this announcement.

However, Auerbach P disagreed because patients in the study received very small doses of vinegar, therefore, this conclusion was not valid. Furthermore, Auerbach P stated that based on his experiences in treating patients stung by box jellyfish he found that patients had good results when applying vinegar [ 15 , 24 ].

In this study, only one of the fatal cases received vinegar as first aid but might be not appropriate. The fatality did not receive vinegar until 20 min after the sting. One fatal case in this study had fresh water poured on to the wounds and icepacks applied. It is now known that application of fresh water and ice cause greater firing of nematocysts, hence these treatments are contraindicated for first aid for box jellyfish stings [ 13 , 25 ]. The incidents occurred more frequently in the southen part of Pha-ngan island which face the northern part of Samui island.

However, the northern part and other areas also had incidents data not shown for mild to moderate cases. Based on the experience of investigating the box jellyfish problem for this study on both Pha-ngan and Samui islands, it was found that people do not believe or do not know that the incidents are more prevalent than their perceptions.

These perspectives were demonstrated at several meetings and workshops carried out over the past 7 years. After the death on July 31st this year, another severe case occurred on the island of Samui on September 12th at Chawang beach on Samui island. This occurred to a 31 year old Chinese male, who was stung by Chirodropidae. Stakeholders start to concern about this health problems and want to know more about the magnitude in these islands.

The findings of this study are useful for providing scientific evidence of the magnitude of the box jellyfish stings and also for convincing the communities to take the problem seriously.

An Australian teenager has died after he was stung by a box jellyfish while swimming at a Queensland beach. The year-old boy's life support was switched off in hospital on Monday, about a week after the incident, Queensland Police said. His death is the first fatality caused by the species in Australia since , local media reported.

The Australian box jellyfish - so named for its shape - is considered to be the most venomous marine animal. It has long barbed tentacles which are covered in pockets of venom. When injected into people or animals, it can lead to paralysis, cardiac arrest and death.
