This undated photo from the California Academy of Sciences in San Francisco, Calif., shows a specimen of a new family of spiders, which scientists are calling Cave Robber (Trogloraptor marchingtoni ) for its fearsome claws. Amateur cave explorers found the spider in 2010 in a cave outside Grants Pass, Ore., and sent specimens to the California Academy of Sciences, where scientists decided it was so evolutionarily different that they had to create a whole new family to put it in. The discovery is described in an article published Friday in the online edition of the journal Zookeys. (AP Photo/California Academy of Sciences)
