This is the 'official' Boa Constrictor, native to Northern South America. Also known as the Colombian Red-tail Boa. Buenos Aires Zoo. In context at www.dixpix.ca/Amazon/fauna/snakes/index.html
Named "Celine" before we learned "she" was a "he". Six foot red-tailed Boa (B. constrictor constrictor). Still haven't figured out how he turned on the TV with the remote and changed channels to "Animal Planet".
