Normally I would not respond to this, but since no one has in a week, I will tell you what little I know.

The BCC is the scientific name of the Boa, and BCI the actual name, and RTB is the Red Tailed Boa, also known as the common Boa.

Males in my neck of the woods typically get 6-8 ft in length, with females being a few feet longer. Of course you always hear about longer ones.

I've seen pictures of a few morphs, but can not remember the names except for the easy one, Albino.

Sorry I can't help more. I'm new to Boas, just testing the waters myself. I only have a Ball Python.

Good Luck
