Curmudgeon is really good at finding these (from Simple RAW):

From this it follows that you cannot EVER identify a lycanthrope in its hybrid or animal form, as anything, because it isn't in a Humanoid aspect and it doesn't actually have the Animal type. It can look exactly like a wolf (eg), but no amount of Knowledge: Nature will tell you that it is a wolf, or for that matter that it isn't. You just don't even get to roll because there's no skill that applies to identifying it.

I really want to know how, let alone why, anyone EVER plays "100% RAW, no exceptions", as Curmudgeon at least has stated he does.
