A. Crikey, I have to say this one sounds like a monster. Do I think people like this ever change? No I don't. This man, with his at least two affairs (have you asked him how many? Could you trust him to answer honestly?) sounds like a compulsive philanderer. The thing about serial cheats is that they need someone to cheat on. Since his marriage ended, there is a vacancy for a Wronged One in his life, the job description for which really doesn't bear thinking about.
Currently acknowledged subspecies include: B. c. constrictor, B. c. orophias, B. c. imperator, B. c. occidentalis, B. c. ortonii, B. c. sabogae, B. c. amarali, B. c. nebulosa (Dominican boa, recently elevated to full species), and B. c. longicauda.
The boa constrictor has a powerful jaw, but it's used for grabbing prey, not for chewing. Boas swallow their prey whole and once digested, won't need to eat for weeks. Boa constrictors are endangered in some parts of their range, where people have hunted them for their colorful skins and the exotic pet trade.
