The first new spider species discovered in North America in more than 110 years has been found in the caves of the Pacific Northwest, reports the Telegraph. The Trogloraptor, or "cave robber" spider, measures about three inches long when outstretched and is seen as a "fierce, specialized predator," according to the Los Angeles Times. "For a spider, this is a pretty big one," says arachnologist Charles Griswold, who compared the discovery to finding a spider Bigfoot. "It has remarkable claws and feet which are like scythes or hooks. We think these work to snap and trap their prey."
Much is still a mystery about these newly discovered spiders, although scientists think the Trogloraptor evolved separately from more commonly known spiders thanks to their remote cave locations. "If such a large and bizarre spider could have gone undetected for so long, who knows what else may lurk undiscovered in this remarkable part of the world," says the study.
