A scientist has been studying a colony of 25,000 Giant Tarantulas living on a flood plain in the Northern Territory of Australia. He's retiring from the task.


Someone young can take over, you'd need to be able to run.


Field of screams: The mystery of Maningrida's 25,000 tarantulas

It's not so much a field of dreams as a field of nightmares: A 10 kilometre floodplain infested with 25,000 tarantulas.
Arachnologist Dr Robert Raven thinks the discovery of this Northern Territory tarantula mega cluster is a good thing for the remote community of Maningrida, 500 kilometres east of Darwin.


It's one of the beauties of science, being able to say 'I don't know.
He says the tarantulas' venom - powerful enough to kill a tiny animal and certainly strong enough to induce nausea and vomiting in humans - could be exploited for medical research: "Pharmaceutical applications could apply across a broad spectrum."

Dr Raven said that such a high concentration of spider was "so far off the scale, it's unbelievable. Normally, I find two or three hundred spiders in one spot."
The causes of the tarantula population explosion remain a mystery.
"Presumably, something is missing that would hammer them or there is something good [like a food source]," Dr Raven said. "It's one of the beauties of science, being able to say 'I don't know.'"

Fortunately for the inhabitants of the small town of Maningrida, tarantulas are not fatally poisonous to humans.

"One of the traditional owners was bitten in eastern Australia and had six to eight hours of vomiting," Dr Raven said. "These are not shallow bites. Long fangs can potentially do damage by ripping tissue."

Nevertheless, local schoolchildren filmed by ABC News on an excursion to the tarantula field did not seem too alarmed. Locals were even filmed patting the spiders.

Discovered in 2006, this species of tarantula is yet to be given a scientific name. The burrow-dwelling spiders are known as diving tarantulas, as they cannot be drowned. They create air bubbles to survive when the plain is underwater during the wet season.

But Dr Raven is now looking for someone to take over his work with the hairy, eight legged creatures.

Researchers wanting to study the Maningrida tarantula may need to take some factors into consideration.
"Someone who is based out in Darwin [should apply]," Dr Raven said. "You'd need a serious degree of understanding and empathy with the local indigenous community."

Asked why he doesn't want to further the research himself, Dr Raven said, "Someone young can take over, you'd need to be able to run."

Not from the tarantulas, though. "There's buffalos and pigs."

I'm wondering how they respond to diesel engines. The trapdoor spider of NSW likes the tick tick tick of the diesel engine and will come out for a look if one is running near by. So if you are camping in NSW make sure it is not in a trapdoor colony otherwise you might get some visitors if you are running your engine.

500 kilometres east of Darwin
I always thought distance from Darwin was measured in years rather than kilometers.

i don't think it's a major mystery.

usually there's only one thing that allows populations to spike like that - a major food source.

Was in my bedroom and a small jumping spider on a wall, that I have been watching has not moved in quite awhile.

So

knowing that jumping spiders have excellent eyesight I decided to frack with it. Dug out a Lazar pointer just to see if the spider could see the light. It could and also instead of running away the spider chased it all over the wall and trying to jump on it.

Twas a hoot !

Not many spider edibles in the room, so I figured that spider was hungry, so I took mercy on it so it was corral the spider time !

Not easy, remember they can jump !

It took some time to catch that sucker with out harming it, but caught it was and carried outside to the yard where all the munches it could ever dream about eating. It was safe in the house, tho slowly starving, outside everything is going to want to eat it, but it is a eat or be eaten world out there.

Still a hoot, a spider chasing a Lazar pointer light dot !

I imagine a laser would also blind it.

I wondered abt that, tho when I took it outside, I watched it for a while. It seemed fine, the laser was only abt 50mw.

Sure could chase the red dot just fine!
