Tortoises, Terrapins & Turtles of Africa [PDF ebook] 

Africa has a rich diversity of tortoises, terrapins and turtles. This authoritative field guide is richly illustrated with colour photographs that make for easy identification of the 46 African species; it provides accessible, up-to-date information and distribution maps, and examines how these creatures have adapted to their environments. The book offers an overview of their origins, anatomy and biology, their conservation status and the threats to their survival posed by the destruction of their habitats by man.
