So what exactly are the differences beteween bcc and bci? They are both called red tailed boas as their "common name", right?

I've read that bccs are bigger, but other than that I don't know what makes them different.

Are they actually different species, or just seperated enough by locale to have specific designations?

Is their husbandry the same?

Just some questions from someone curious about the ambiguous information on the internet.
