As an illustration I’ve posted an update on the 2015 Silver-back Bolivian Boas. Included are new pictures showing their development thus far. The contrast of the silver background and thin dark saddles is very nice, though hard to capture in photo’s.
Considering these Bolivian Short-tailed boas are getting lighter with every shed, I would expect these Bolivians will continue to demonstrate lighter background in each subsequent shed. Probably a few she cycles in and we’ll get a good idea of how each animal will look.
