Telenothians: An Inquiry into the Limits of Hybridization investigates one primary question: How different can two organisms be if they are to mate and produce offspring together? Most readers will be surprised at the answers this book provides. Gleaned from a wide variety of sources, ancient and modern, the vast array of information collected here is drawn from medical reports, scientific journals, newspapers, magazines, viral videos and dusty tomes. The contents include hundreds of examples, often with detailed descriptions, together with illustrations and photographs. Many of these are both fascinating and unsettling in equal measure. Telenothians provides in-depth knowledge about a wide variety of distant hybrid crosses involving either mammals or birds. These books show that hybrid crosses can occur between creatures far more different from each other than science has deemed possible.

Available in three volumes, Telenothians documents a wide variety of astounding births, some three thousand separate cases. It includes an index, hundreds of illustrations, a list of works cited, and a complete timeline. This publication is available in both a deluxe (color, hardback) or an economy (b&w, paperback) edition.

This, the second volume (526 pages), deals with reports describing composites not covered in Volume I.
