Boa constrictor occidentalis

Argentine boas are classified under this unique Boa constrictor subspecies.  A fairly large boa, Argentines offer a very different appearance than other subspecies.  This is the only subspecies currently listed as endangered by CITES (Convention on the International Trade in Endangered Species) and is listed under Appendix I.  This prohibits export from native countries and requires special permits for import and export of captive bred animals between countries.
