Fish-Eating Spiders Are On Every Continent But Antarctica (PICTURES)

Nightmare Fish-Eating Spiders Are Lurking On Every Continent Except Antarctica (PICTURES)
|

Not content with hiding in boxes of bananas, lurking creepily in dark corners and trying to sink their fangs into sweet, sweet human flesh, spiders are now devouring FISH.

Yup, and what’s more size is no object to the large, semi-acquatic pisaurid spiders of the genera Dolomedes and Nilus (‘fishing spiders’), who are happy to take on prey more than twice as big as they are.

The unnerving research was gathered by Martin Nyffeler from the University of Basel in Switzerland and Bradley Pusey, from the University of Western Australia and published in the science journal Plos One.

Nom nom, pass the chips

And it’s not some exotic occurrence none of us have to worry about ever witnessing – these arachnids are demonstrating pescatarian tastes on every continent except Antarctica.

Fish-eating spiders tend to live in freshwater environments like ponds and wetlands. Some can even skim, dive and walk on the water’s surface.

“From the records that we’ve reviewed they then usually just kill their prey with a bite at the base of the neck.

“It can take many minutes for the fish to die, and it is probably safer for the spider to haul it out of the water to aid in handling and reduce the potential for escape.”

One way ticket to Antarctica, please.

Despite their name, they aren’t only found in Brazil – they’re native to South and Central America. (credit:WikiMedia)

They are so named because they are typically found wandering across the jungle floor at night – presumably when the other spiders are safely tucked up in their beds. (credit:Flickr:tai strietman)

Their bite is 30 times more deadly than that of the rattlesnake. So potent is their venom, just 0.006 mg (0.00000021 oz) is sufficient to kill a mouse. (credit:Getty Images)

It is the presence of PhTx3, a potent neurotoxin makes the spider’s bite potentially lethal. (credit:WikiMedia)

Milking for venom(08 of10)

An effective antivenom has been developed, known as Soro antiaracnidico. Antivenom is typically created by milking venom from the desired spider, insect or snake (as illustrated) then diluted and injected into a horse, sheep or goat. The subject animal will undergo an immune response to the venom, producing antibodies against the venom's active molecule which can then be harvested from the animal's blood and used to treat envenomation. Internationally, antivenoms must conform to the standards of pharmacopoeia and the World Health Organization (credit:WikiMedia:)

A toxin from the venom – PnTx2-6 - boosts the availability of nitric oxide, a chemical that dilates blood vessels and increases blood flow. This means bites can lead to priapism – a persistent, usually painful erection. A study published last year in the Journal of Sexual Medicine suggests the toxin could be used to help treat erectile dysfunction in humans. (credit:Flickr:Simon Strandgaard)

A website maintained by Rod Crawford, curator of arachnids at the University of Washington’s Burke Museum, maintains that deaths from Brazilian wandering spider bites are rare, with only 10 fatalities in more than 7,000 reported cases. (credit:Getty)
