How do you tell?

[Domepiece]

I have had many BP's but I never realized there were so many different kinds. How do you know what exact kind of bp you have? I assume the new one I have is a Monty Python. It was on the cage so wasn't sure if that was the name given or what.

The young one I have (in my avatar) I haven't a clue as to what kind she is. I knew about Albino ones but since I joined here, I couldn't believe how many different ones there really were!

It looks like a normal ball python to me. Monty just might be his name. You would more than likely know if it were a morph of some sort. Check out this website, it has a lot of morphs on it.
