14. Hooded Seal
As you can see from this photo, hooded seals are very special. Located in some parts of the North Atlantic, the males of this species have a bulbous hood on the top of their heads. As for that red ‘bubble,’ it’s actually the extrusion of an internal membrane that starts in one of the nostrils and is used, of course, to impress the ladies (because why else would you grow something like that?).
