Boa constrictor is a species of large, heavy-bodied snake. It is a member of the family Boidae found in North, Central, and South America, as well as some islands in the Caribbean. Non-native boa constrictors, which can exceed 10 feet and 75 pounds, have established a breeding population in Puerto Rico, one that appears to be spreading, according to research published in the journal Biological Invasions. While boa constrictors and two species of pythons have established invasive populations in Florida, this research is the first to document a large constrictor species established in the United States or its territories outside of Florida. The new population appears to be spreading from its likely point of origin in the western part of the island around the city of Mayagüez. In the last year alone, more than 150 boas have been found in the wild on the island.
