In this April 18, 2002 file photo taken at James Cook University in Cairns, Australia, a tiny but fully grown deadly Irukandji jellyfish lies next to match sticks for size comparison. Ben Southall — who won a contest to blog for six months about life on Australia's Hamilton Island to promote tourism — wrote Tuesday Dec. 29, 2009, that he was lucky to have survived his brush with the extremely venomous Irukandji jellyfish.

Ben Southall - who won a contest to blog for six months about life on Australia's Hamilton Island to promote tourism - wrote Tuesday that he was lucky to have survived his brush with the extremely venomous有毒的，恶意的 Irukandji jellyfish.

Earlier this week, Southall was getting off a Jet Ski in the ocean when he felt "a small bee-like sting" on his arm. When he later noticed a tingling³刺痛 in his hands and feet, island staff took Southall immediately to the doctor.

Progressive symptoms症状 of fever, headache, lower back pain, chest tightness and high blood pressure led the doctor to diagnose that Southall had been stung by an Irukandji jellyfish. He was given pain medication and slept off the venom's effects overnight.

"I thought I'd done particularly well at avoiding any contact with any of the dangerous critters生物，小动物 that consider this part of the world their home," Southall wrote. "This was not what I'd wanted at all and had caught me little off guard to say the least - I'm supposed to be relaxing in my last few days on Hamilton Island."

Australia is well-known for its myriad无数的，种种的 deadly creatures, but the peanut-sized Irukandji remains⁵ rather mysterious. It is virtually impossible to see and is tiny enough to pass through nets meant to keep jellyfish away from popular swimming spots.

Its sting can lead to symptoms including shooting pains in the muscles and chest, vomiting⁶, restlessness坐立不安 and anxiety. Some symptoms can last for more than a week, and the syndrome⁷综合症 can occasionally lead to a rapid rise in blood pressure and heart failure.

In 2002, two tourists were killed in separate incidents after being stung by the tiny creatures off northeast Australia - the first recorded Irukandji fatalities⁸.

"My slight knock was enough to tell me that it's not something to be messed around with," Southall wrote of the jellyfish. "I really should have been wearing a full stinger suit, as it recommended at all beaches here at this time of year."

He said he was feeling well and was enjoying his last week on the job.

The 34-year-old former charity worker bested nearly 35,000 applicants⁹ from around the world for the dream assignment that started in July to swim, explore and relax on Hamilton Island in the Great Barrier Reef while writing a blog to promote the area and earning a salary of 150,000 Australian dollars ($120,000).
