John Berry has been fascinated with wildlife and has kept reptiles almost all of his life. He is a popular speaker, author and writer with a vast in-depth knowledge of his chosen subject. 

Containing over 620 full colour photos, the book describes all known mutations, variations and designer-morphs for two of the most popular species among python and boa keepers; namely ball pythons (Python regius) and boa constrictors (Boa constrictor ssp).

The book presents a vast amount of well researched information in a format that is both easy to follow and understand. As a reference guide with detailed descriptions of the genetics behind most multi-gene designer-morphs, this book is indispensable and will be referred to many times by both breeders and keepers alike.
