Scientists from the California Academy of Sciences and cavers from the Western Cave Conservancy have found a new spider in caves in southwest Oregon, called Trogloraptor, or cave robber. This spider is so different that it is not only a new genus and species, it is a new family (Trogloraptoridae). The spider is four centimetres across with legs stretched out, has large and sharp claws, and hangs underneath webs on cave ceilings. If they have only just found this one – what else is lurking in there?
