Boa constrictor constrictor. The boa constrictor is a large snake, although it is only modestly sized in comparison to other large snakes such as the reticulated python and Burmese python, and can reach lengths of anywhere from 3â13 feet (0.91â3.96 m) depending on the locality and the availability of suitable prey. young boa constrictor should be kept in a relatively small enclosure such as a secure plastic box or terrarium. As the boa grows, so too should the size of the enclosure. Adults are often housed in 180 cm Ã 90 cm Ã 60 cm vivariums, however large females should be placed in larger enclosures.
