50 new spiders discovered in Australia

The new spiders range from tarantulas the size of a human face to ant-mimicking spiders smaller than a thumbnail.

A two-week expedition in Australia’s Cape York Peninsula has uncovered 50 new species of spiders.

The expedition, which identified spiders ranging from tarantulas as big as a human face to ant-mimicking spiders smaller than a thumbnail, involved 23 scientists, indigenous rangers and traditional owners. The surveys were part of the Bush Blitz discovery project, a partnership between the Australian Government, BHP Billiton Sustainable Communities and Earthwatch.

The diversity of spiders in the area was “mind blowing”, Robert Raven, the Principle Curator of spiders at the Queensland Museum told Australian Geographic in an interview.

Under just one rock, Raven found spiders from six arachnid orders. “It was absolutely spectacular to see all these six groups together,” he said in the interview.

This expedition is likely to result in the greatest number of new spiders discovered on a Bush Blitz research trip, scientists say. Bush Blitz expeditions have discovered nearly 1,200 new species till date, including 201 new species of spiders.

“This was one of the largest number of species Bush Blitz has ever discovered during one expedition,” the team said in a statement. “Far north Queensland can boast an extraordinary variety of spiders.”

The researchers are now identifying and describing the spiders for formal scientific classification.

This is the first time the West Quinkan in Cape York Peninsula has been biologically surveyed, said Brad Grogan, Western Yalanji Aboriginal Corporation manager. “Hopefully this expedition will help us identify areas of natural values that we can protect for the future.”

It's incredible how new life is always being discovered in places right under our noses! Makes you wonder what else is out there that we have not found yet


I'm with you... This said, I do particularly like this last one on the list. How is it that colors always appear to match so perfectly well on all wildlife? Blue eyes and purple sunglasses... wow!


Cool discovery, but I cannot say I will be on the lookout for any of these spiders! No thank you.
