Some other books to note are:
- Pythons Of The World, Vol. II: Ball Pythons, by David & Tracy Barker (Vida Preciosa International)
- The Complete Ball Python, by Kevin McCurley, (New England Reptile Distributors)
- The Complete Boa Constrictor, by Vin Russo, ( Cutting Edge Herpetological)
If you want to check out the smallest of the pythons, there is the Antaresia group. These are the Children's Python, Stimson's Python, Spotted Python, and Anthill Python.
There are also some of the "dwarf boas" that stay in the 4-6 foot range...
