Ok so I was trying to compare yours to mine. I was also taking a look at the Nerd site. Keep in mind that I am super super new to this. I got my snake for a super reputable breeder so I have NO DOUBT it is what I was sold.
What I did see is that a butter has light eyes (I know that mine does) while a mohave looks like it has dark eyes. Not sure if this is is across the board. I am sure someone could inform me better.
