This has occured to me for a while soon, and this has probably been answered already, but why are there 16 daedric princes? When not all of them are male, shouldn't some of them be princesses, unless they are of course trans-gender.
From my understanding, the daedra princes are sixless (prince shouldn't connote gender in this case). They might assume a particular appearance when visiting Nirn, possibly inspired by what their followers think they look like based on their attributes.
