Do the Wanyonya damu have fangs when they bite au they just dont have them at all?

They don't have them at all. Stephenie explains about their fangs link.

"My Wanyonya damu do not have fangs. Their teeth are so sharp and strong that fangs are hardly necessary (they could bite through steel, if so inclined–a human neck is like butter, ha ha). The non-vegetarian Wanyonya damu don’t leave living victims (unless they are changing someone into a vampire); this isn’t the neat-and-tidy, two-small-holes-in-the-neck kind of vampire attack that wewe see in other vampire mythologies."

stephanie meyer's Wanyonya damu don't have fangs and are nothing like Wanyonya damu we used to, so everything wewe know about them (vampires from awali vitabu and movies), all the myths,it doesn't involve stephanie's vampires.. so they don't have fangs but do have very sharp teeth with venom in it.. that's why edward doesn't french kiss bella, because she could easily cut herself..

twilight Wanyonya damu dont have fangs because their teeth are already sharp enough thats why when they bite someone, it makes a cresent mark, not two little holes

Wanyonya damu are REALLY different in stephenie Meyers books, we wouldn't expect any Wanyonya damu to be vegetarians would we, we thought Wanyonya damu would be all gothic, biting humans, having fangs ect. But in stephenies vitabu everything is different, thay can be vegetarians, they are not all gothic and THEY DONT HAVE FANGS AT ALL!!. xx Also instead of making 2 little holes like a vampire with fangs would, it makes a creasent mark.

Idek

yes but not in Twilight

No, those 'Vampires' don't have fangs.
Coming to think of this, having read some of the vitabu and seen all of the sinema due to being a movie/book reviewer for a local paper... I can, as a mythology shabiki as well as a die-hard horror story/movie fan, say I don't even see them as vampires.
Calling these creations Wanyonya damu is like saying a white dog with black spots is a cow au a panda-bear: They share similarities, yes, but they aren't what wewe call them. I prefer to see them as disco-globe mosquitos.

Wanyonya damu do not exist so the swali is invalid.
