BCI and BCC are subspecies, along with Amarali, Longicauda, Sabogae, etc. BCI is your typical common boa, usually from colombia. This is what most of your morphs will be unless they are crossed with other subspecies. Dont confuse this with the locality of the boa, which may be any of the subspecies (Hogg Island is a BCI for example, and is naturally hypomelanistic, but a totally different snake than a hypo colombian BCI). In general BCC's have the bat like widows peak saddles and a blood red tail, which is why they are called the "true" redtails. They may not be as tame as a BCI either, especially when wild caught. When raised from babies and captive bred they can be just as calm though. To make things even more confusing each locality has its own distinct markings. Some boa keepers are into morphs only, and in this case you are dealing mostly with Colombian BCI. Other more "purist" keepers view morphs as the propagation of genetic defects, and only deal with the various subspecies and locality boas, which all have their own unique patterns and colors in the "normal" form. Some such as myself enjoy them all! Check out Vin Russo's site cuttingedgeherp for some good info on subspecies, localities, etc.
