I've been looking at morph pics since i found out about BP morphs. I have a pretty good idea of what makes up the morphs that I want to add to my collection. It really helps if you have a normal to compare them too.

Like Robin said, a screaming morph example is unmistakable. These animals are both owned by Adam of 8ball pythons (at the time i took the photo, Nov/Dec 08). The left is a normal and the right is an enchi. The type of enchi I would want. There is no mistaking that animal for a normal.
