Venomous New Pseudoscorpion Found in Colorado Cave
Nearly blind animal has venom-tipped pincers.
The 0.5-inch-long (1.3-centimeter-long) species, Cryptogreagris steinmanni, was discovered recently in high-altitude caverns near Glenwood Springs, Colorado.
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, 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. Steinmann
