It seems as though there are not any boa constrictor facts that are not either unique, fascinating, frightening or just incredibly intriguing.  Native to Central and South America as well as the Caribbean, they are one of the easiest recognized varieties in the world.  Below are the top 15 most interesting boa constrictor facts that are known about these large snakes.

  1. One of the scariest boa constrictor facts is that if they feel the least bit threatened, they will attack and bite in self-defense.  This is often incredibly painful because they do have teeth but rarely considered dangerous.  It is however, very important to make sure that the wound does not get infected.
  1. Boas that are shedding are much more unpredictable than others.  Juveniles are likely to attack more than adults because they shed more often which causes a film to cover their eyes so they cannot see well.

  1. Digestion is one of the most interesting topics of boa constrictor facts.  These snakes use their teeth to force their prey down their throat.  At the same time, the muscles move the food toward their stomach.  It typically takes anywhere from four to six days for the food to digest completely depending on the temperature and what the snake ate.  They have an incredibly slow metabolism so they will often not eat again for one week or several months.
  1. A female boa can store sperm inside of her after copulation for up to one year to decide when she will ovulate.  Gestation period can last up to 120 days and she can give birth to up to 65 young in one litter however 35 is the average.
