The new pseudoscorpion is top of the food chain in Glenwood Caverns. Photograph courtesy Dave Steinmann Christine Dell'Amore _National Geographic News_ (http://news.nationalgeographic.com/) Published February 4, 2011 Unless you've been living in a _cave_ (http://science.nationalgeographic.com/science/earth/surface-of-the-earth/caves-article.html) , you probably haven't run across this new species of poisonous, nearly blind pseudoscorpion. The 0.5-inch-long (1.3-centimeter-long) species, Cryptogreagris steinmanni, was discovered recently in high-altitude caverns near Glenwood Springs, _Colorado_ (http://travel.nationalgeographic.com/travel/united-states/colorado-guide/) . Pseudoscorpions are essentially scorpions that lack a stinging tail. However, the new species does have long, venom-tipped pincers that likely help it nab agile prey, such as springtails, in the gloom. Most likely, the new pseudoscorpion lives only in _Glenwood Caverns and Historic Fairy Caves_ (http://glenwoodcaverns.com/glenwood-springs-cave-tours.html) , the study authors say. "A lot of these caves are islands, almost like an isolated environment where invertebrates ... evolve into being adapted to underground life," said biospeleologist David Steinmann, a zoology department associate with the _Denver Museum of Nature and Science_ (http://www.dmns.org/) . Steinmann collected the new species after it was discovered in 2000 by tour guide Micah Ball. With its primitive eyes and pale color, the arachnid is perfectly suited to its dark, chilly existence and has probably been scurrying through the passages for millions of years, Steinmann said. New Pseudoscorpion Elusive—Until Now Little is known about C. steinmanni, but it's thought to be rare, relatively long-lived, and able to curl up into a defensive ball when threatened. The animal went unnoticed for so long because it blends in well with the rocks—and because few people have been crawling around caves looking for tiny creatures. Steinmann, an avid caver, has discovered more than a hundred new _invertebrate_ (http://animals.nationalgeographic.com/animals/invertebrates/) species so far in Colorado caves, including at least seven in Glenwood Springs alone.

The new-pseudoscorpion study appeared in December 2010 in the journal _Subterranean Biology_ (http://www.fi.cnr.it/sibios/subtbiol.htm) . _http://is.gd/eoUY5r_ (http://is.gd/eoUY5r)
