I am doing a report on various Boids. I have owned burmese and researched that they have "cousins" that are related. The problem I have is trying to catagorize by appearance based on location of the main Indian python(light colored) from the subspecies the Burmese(usually darker), the Ceylonese(also light colored), Sri Lankan, or a Cross of the Burmese/Indian. Is there a way to tell them aprt by looking at them or not that is just a myth? Your help is much appreciated. Thankx.
