There is a bit of long story concerning the BCS and the fact that many which were brought into the states when they could still be exported from the islands were not actually pure. Vin wrote a great article about this that was published in a reptile magazine awhile ago. If you study the Pearl Islands chain and compare distance between the islands themselves, and the mainland, the BCS were able to swim from island to island and to the mainland to mix with BCI. Over hundreds of years this produced a lot of variation in the BCS from most of the islands. The island of Saboga however, is far enough away from any other land mass that the chances of this happening were very slim. Therefore, only the BCS that were positively known to have been collected from that island were known to be pure. There are not supposed to be any BCI on Saboga.
The size they can achieve depends on their source because of this. The pure BCS stay very small and slender. Females should max out between 4-5 ft. I’ve seen “Pearl Islands” boas that were a bit bigger but they also did not look pure and were likely mixed with BCI somewhere along the lines. Just by looking at them you can see they look different from BCI. Not just the color and pattern, but the long, slender, pointy head. Lack of eye stripes and head T. Just subtle things like that.
