I could've done that myself...the point of asking here was to hear several opinions from educated reptile keepers...not idiots from yahoo answers
The best answer I did find was this...
But even then...not a very scientific classification...considering the exceptions to their live birth/egg laying rule.They both exist in varying parts of the world. They have similar habitats, but differing care should be practiced on each. This also varies between what TYPE of Python or Boa you have. Again, this caresheet is for Red-Tail Boas, or the classification of Boa Constrictor, only.
Red-Tail Boas come from South America, Central America, and the islands surrounding each. All types of Boa give live birth (except one type of boa), where as pythons will generally lay eggs.
