In our next article series, we represent some the changes of appearance of some true Boa constrictor localities througout the years...

Newborn Boa c. occidentalis differ from their parents significantly. They are pale greyish, sometimes pinkish, their patterns look blured with less contrast. However, they will change in the next few years. Adult specimens take a dark brown, black overall with white spots outcropping. Oldest specimens may appear jet-black.
