Meet Trogloraptor, a New Kind of Spider

A spider recently discovered in caves in the Pacific Northwest is an odd beast: not only is it a new species, it’s got its own genus and even family to itself. Up to three inches wide with its legs extended, it sports long, sharp claws that suggest it’s a keen predator of some sort, but scientists currently have no idea what it eats. It was discovered hanging from rather messy webs on the ceilings of caves, as well as in undergrowth in redwood forests. Its genus name, Trogloraptor, means cave robber.

Former 80beats blogger Doug Main, now at Our Amazing Planet, has interviewed the scientists who made the discovery and has plenty more interesting details. Head on over to learn more, and to see pictures of its claws.

    I wonder if they eat small bats. I feel like I’ve seen large spiders catching bats on a nature show before (though obviously not this guy).

    Wish they will put it up in pet stores someday. “Hey look Ma, I bought a new spider today!!!”

    I predict that it eats banana slugs. Remember; you heard it here first.

      I’m making a note here…

    They took the spider from a cave where it’s kind may have lived for millions of years, undisturbed, and they call the spider “Cave Robber”? Isn’t that just a tiny little bit like calling Native Americans “Land Grabbers”? I am not a spider or Native American activist, but the label they stuck on that spider made me laugh.

    it’s getting the time of year when I seem to be walking through spider webs all the time. I would hate that thing crawling on me.
