B.C.I Cross (Double Het John Berry Blood El Salvador Boa/Leopard Sonoran Desert Boa)

Another well known population of B. c. imperator is the population from Nicaragua. While not as small as the dwarf insular island populations, adults are still smaller than the larger B. c. constrictor. The size of a mature female Nicaraguan boa is 1.1 m and 1.9 kg, while the larger female B. c. constrictor is not mature until she reaches 1.6 m and 4.5 kg.[4] Nicaraguan individuals typically have a compact saddle pattern on their backs that is often circular in shape. These boas have a reputation for being "nippy", with some individuals being quick to bite in self-defense.
