The cartoons tell us that this is exactly what a beaver looks like. But actual eyes and hours of watching tells us otherwise. My band of beaver-watching friends agree that this beaver actually has an old injury to his lip on the right side of the frame and that’s why we see his top teeth and tongue are so clearly in this shot.
It looks just like the cartoons but trust me its not normal. Although he seems to be doing just fine. And remember he has another set of lips behind his teeth to do whatever this one couldn’t.
Thanks to Mike Digout for this rare glimpse.
