Yes, the claws are the size of adult human fingers, but wow! (Please don't be concerned about the bear's safety. It is tranquilized and about to be released back into the wild).
Richard Thompson, one of my top three favorite singer/writer/guitarists, wrote and performed the music for "Grizzly Man," Werner Herzog's 2005 documentary of Timothy Treadwell's life -- and death -- with grizzlies.
Enjoy this music, created by a master musician, and imagine living with these magnificent gargantuan creatures. ~ GH
