A group of cave explorers in southern Oregon discovered a new family of spider that grows up to three inches long and wields hooklike claws at the end of each leg. The claws are most likely used to snatch insects like midges midflight. The spider, Trogloraptor marchingtoni, has poisonous glands but is not considered dangerous to humans. It is the first native spider family identified in North America since 1890.
