Boa is a genus of non-venomous boas found in Mexico, Central and South America, Madagascar and on Reunion Island. Four species are currently recognized.[2]

The largest member of this group, B. constrictor, has been reported to grow to a maximum of 14 feet (4.3 m) in length.[4]

Taxonomy

Kluge (1991) [5] moved the genera Sanzinia and Acrantophis into Boa, based on a phylogeny dereived from morphological characters.

However, it was later found that the Malagasy boids and Boa constrictor do not form a monophyletic group, so that the lumping of Sanzinia, Acrantophis and Boa were probably in error, and most recent authors have reverted to the use of Sanzinia and Acrantophis as the genus name for the Malagasy boas.[6][7]

To add further to the naming confusion, many species of snake in the family Boidae are known as "boas" and all are constrictors. Also, more than a few subspecies of B. constrictor are recognized, several of which have distinct common names.[3]
