Jellyfish defends itself from vicious attack by 3 kids!!!!!

Cairns Post headline writer at work

Three Mornington Island children were stung by a jellyfish yesterday after they callously swam into the creature, which was peacefully swimming by trying to catch some small fish or prawns for lunch.

The children were taken to the island’s hospital for treatment, with two released shortly afterwards. The third remains in hospital in a stable condition. The fate of the innocent and unidentified jellyfish is unknown.

Authorities have denied that the population of children is out of control, and said that a cull is not being considered. Child-proof netting is installed at many Far North Queensland beaches to contain the menace and protect jellyfish, but it is sometimes difficult to keep children inside the designated areas.

Bluebottles on a blue sky day

December 22nd, 2009

Trinity Beach today

Wandering along the beach this afternoon, I noticed a bluebottle a few meters out from shore. I stopped and looked at it for a moment, and thought about how it could wash onto the beach and sting someone.  A few steps later a wave washed in around my feet. I felt something snag on both my feet. Looking down, I saw another bluebottle and realised I had been stung.

There was no immediate pain. It took about thirty seconds before a sensation a bit like pins being pushed into my skin developed. It was only slight, though unpleasant. A little further down the beach I found one of the vinegar bottles put out by the sur lifesavers, and that seemed to do the trick.

I wandered on to the café with crashed with an iced chocolate and Supersense by Bruce Hood, which is about the psychology behind supernatural beliefs. It covers everything from our tendency to believe in mind-body dualism to people’s reluctance to wear a cardigan they have been told was owned by murderer Fred West. It’s an informative and at times very amusing read.

My feet experienced a few minor tingles from the sting, but nothing of any great note. No weal, rash or anything showed. It seems my first encounter with a bluebottle was a bit of a non-event. The photo of the bluebottle didn’t come out very well.

Jellies

One of my more memorable experiences on the reef was a day at Reef Magic’s pontoon at Moore Reef when the conditions were just right to bring swarms of moon jellyfish to the snorkelling area. At first it was amazing to be in among so many jellyfish, but rapidly they just became irritating as they bounced along me as I swam and sometimes got in the way of photos. Now I’m thinking things could have been worse.

News sites are reporting on the latest jellyfish plague in Japan, and it would also be an interesting experience for a while. Giant Nomura’s jellyfish have again come to Japan’s coastline. The jellies grow to 6-feet in diameter and 200kg in weight, and cause a lot of problems for net fishermen. This may be poetic justice, as overfishing of jellyfish predators is one of the possible reasons these jellyfish plagues are becoming more common in the area.

Rural graffiti

Crop circle in Oxfordshire, England

Crop circle in Oxfordshire, England

This week’s episode of the Skeptics’ Guide to the Universe had a brief news item mentioning a jellyfish crop circle. Intrigued, I had to google it. One of the podcast panet suggested it was “rural graffiti”, which I think an apt term for art like this.

It must really annoy the farmers though. According to the BBC, the damage to the crop from this one is estimated at £600.

Another list of things that have caught my eye

November 10th, 2008
  • The Boxing Day tsunami in 2004 caused severe damage to many reefs in the region. Pak Dodent, a dive shop operator on an island near Sumatra, set about replanting his reef using cuttings from an unaffected reef. After three years of effort, including cleaning algae off new coral with a toothbrush, the results are apparently rather spectacular. A number of news sites are reporting on the project, but the Telegraph is the only one I saw with photos.
  • Science Daily reports on a study on the drinking habits of sea snakes. They have found that sea snakes do not drink salt water and filter out the salt, but drink fresh water from creeks and rivers or from fresh water lensing on the surface of the salt water after rain. The researcher also suggest that the increased lensing in lagoons may be why these areas are often home to good populations of sea snakes. The report also mentions possible population declines and extinctions of snake species at Ashmore Reef as possibly being due to the drought. Ashmore is a sea snake fancier’s delight, and when I worked at HMAS Cairns a number of sailors who had been to Ashmore commented on how unpleasantly common they were there.
  • Jamie Seymour, the James Cook University biologist who spends much of his time researching jellyfish, has spoken out about the lack of funding for Irukandji research. The article comments on an Irukandji breeding grounds behind Double Island, of which I wasn’t aware. This would be one reason Palm Cove, Kewarra and Clifton Beaches tend to be more frequently closed than Yorkeys. Another is possibly the additional silt in the water here from the Barron River and Trinity Inlet.

Stinger season approaches

October 4th, 2008

Following my comments in the croc post yesterday, I note that the Cairns Post is reporting that FNQ Lifesaving Services have started dragging the beaches for stingers. So far they only report ”harmless” comb and button jellies and a few baby prawns. The stingers normally start to appear between mid-November and mid-December, so we’re still six weeks away. Reports from Port Douglas have juvenile box jellyfish (Chironex fleckerii) in the rivers. They’ll probably come out with the first heavy rains.
