The Hedgehog's Talon

A hedgehog's talon sounds pretty intense to me, even if i can't quite picture what that would be. I love stories where beings have a strange, recurring, specific number of body features. It reminds me of visions in the bible, like particularly the visions of the dragon and the beast in the book of revelation. But does that mean seven crowns per head, or just one crown per head? I'm not sure.
