Shadows in the Sea: The Sharks, Skates and Rays

Blurb

Captain Young and I for some years have been gathering material from all over the world about the Selachians—the Sharks, Skates, Rays, and their allies —of which there are more than 600 known species. We originally intended merely to up-date Captain Young's book ''Shark!! Shark!!'''' (published by Gotham House in 1934, and now a collector's item), but, as the material ever expanded, it was decided that an entirely new book, covering a much broader field, was needed. Adaterial was collected from all over the world for many years. When Captain Young and I felt that the research was nearly completed, we called upon Tom Allen, an experienced newspaperman, to aid us in transforming the research material into a book. Tom and I continued the research up to (and beyond!) the completion of the manuscript. Tom also did further research and added new material in the course of writing the book. In all scientific classifications, the Selachians are separated clearly from the Teleosteans, or Bony Fishes, and there are even leading ichthyologists \\ ho do not regard the former as fishes at all but rather as representing a separate and distinct Class of animal life...
