Boa constrictor
Depending on the subspecies, "Boa constrictor" can be found through South America north of 35°S (Colombia, Ecuador, Peru, Venezuela, Trinidad and Tobago, Guyana, Suriname, French Guiana, Brazil, Bolivia, Uruguay, and Argentina), and many other islands along the coasts of South America. An introduced population exists in extreme southern Florida, and a small population on St. Croix in the U.S. Virgin Islands now appears to be reproducing in the wild.
