Ever heard of polydactyly or polydactylism? It's such a cool condition!
I have never of that.  Tell me about it.
Well polydactyly is basically having supernumerary fingers or toes.
What does supernumerary mean?
Supernumerary means to have too many, like a person having 6 toes or fingers.
Oh wow, how common of a condition is that?
Well it isn't too common, but it is even less common on both hands or feet in humans or animals.
