hi there, I'm fairly new to tree boas too...actually I just purchased my first one over the weekend; it was labeled "Red Cooks Tree Boa", but I don't think that's correct...as soon as I get a decent pic I'll post it for someone to ID properly. Anyways, I don't know if this will be any help to you, but I found this site quit informative. http://www.corallus.com/species.html
