The photos above jogged my memory about a story from a year ago in the Samui Times. See another photo of a box jelly fish

From the article:

 

"...If you see one of these on the beach do not touch it. The stingers from the Box Jelly Fish can shoot off venom for up to five years after they die..."

 

Five years!!!

If they dropped a few of those nets off the beach in Pattaya, they'd collect more rubbish than the Bangkok canals!

Thanks for your kind offer, but I was not in the mood of tingling with that thing's tentacles, so we have to solve the mystery without the otherwise convincing DNA-method.

 

The weird jelly-thing looked like the so-called "Red fire man" (rød brandmand) from my childhood's Danish beaches – "fire", Danish "brand", refers to that the sting "burns on the skin", "man" or Danish "mand" could refer to only male species, mening they can reproduce without use of females. I remember it as something really nasty to get in close contact with (talk from extremely bad experience:crying:), but probably not that poisoning after all for grownups.

 

Google is my friend, and our "Red fire man" has an English name, "Lion's mane jellyfish". It's a very Northern, almost Nordic "lion", which is »common in the English Channel, Irish Sea, North Sea and in western Scandinavian waters south to Kattegat and Øresund. It may also drift in to the south-western part of the Baltic Sea (where it cannot breed due to the low salinity).« It's also known as the "Giant jellyfish" and »is the largest known species of jellyfish. Its range is confined to cold, boreal waters of the Arctic, northern Atlantic, and northern Pacific Oceans.«

 

OMG, "giant" means giant: "The largest recorded specimen found, washed up on the shore of Massachusetts Bay in 1870, had a bell with a diameter of 2.3 metres (7 ft 6 in) and tentacles 37.0 m (121.4 ft) long.":shock1:

 

But here comes the interesting part: »Similar jellyfish, which may be the same species, are known to inhabit seas near Australia and New Zealand.«

 

Could it – even without DNA testing – be a Lion's mane jellyfish or similar thing..?

 

If so, then Wikipedia says:
»Sting and human contact
Most encounters cause temporary pain and localized redness. In normal circumstances, and in healthy individuals, their stings are not known to be fatal. Vinegar can be used to deactivate the nematocysts, but due to the large number of tentacles medical attention is recommended after exposure.

On July 21, 2010, around 150 people are thought to have been stung by the remains of a lion's mane jellyfish that had broken up into countless pieces in Rye, New Hampshire, in the United States. Considering the size of the species, it is possible that this mass incident was caused by a single specimen.«

And just for reference, a Box jellyfish is supposed to look like this at Wikipedia...

Ahem... are you volunteering? (I expect the answer to be NO!!!)

 

I think I'll put my energy into avoiding them.

Tourists in Samui and Phangan warned - box jellyfish that can kill in minutes have arrived

 

A species of deadly box jellyfish that can kill in as little as two minutes have been located on Lamai Beach in Samui.

Now a hospital on the neighboring island of Koh Phangan has issued a warning to tourists to stay out of the sea at night. The box jellyfish known in Thai as "Maeng kaphun lai sai ( jellyfish with many lines) is a regular visitor to the gulf in July and August.

 

The arrival of one in Lamai is a warning that they are coming said Koh Phangan hospital on their Facebook page yesterday. They warned that the sting from the creatures can kill a human being in between 2 and ten minutes.

They advised operators in the area to stock up on vinegar and warn tourists about the threat and tell visitors to stay out of the sea at night, said Sanook.

Portugese man of war jelly fish are the common blue-bottle often found on beaches in non-tropical waters throughout Australia. The sting is painful but the discomfort usually only lasts about an hour. The sting does not usually cause serious symptoms or death. 

Treatment of a blue bottle sting is to carefully remove the tenatacles, then to apply, or soak the affected region in, hot water (as hot as the victim can tolerate comfortably - Eg. 45 degrees C) for about 20 minutes. 

 

The biggest problem in Koh Samui is the occassional incidence of box jellyfish and the tiny irakungi jellyfish, which can both cause death. These jellyfish usually visit in the months of July-October.

Treatment should be to immediately irrigate the stung area with a LOT of vinegar, and rush the victim to hospital.
