This volume had its origin in a symposium on the Reproduction and Development of Cartilaginous Fishes that was held at the annual meetings of the American Elasmobranch Society and the American Society of Ichthyologists and Herpetologists in Charleston, South Carolina in 1990. The cartilaginous fishes, class Chondrichthyes, are a large and diverse group of fishes that include approximately 900 to 1100 living species of sharks, skates, rays and ratfishes. Throughout their history, which dates back at least 400 million years, they have been a successful major component of the marine ecosystem. The chondrichthyan fishes occupy a pivotal position in comparative and evolutionary studies of vertebrate reproduction and development. They are the oldest surviving group of jawed vertebrates and they possess both the adult vertebrate Bauplan and the vertebrate program of embryonic development. The major features of the female reproductive system, including its embryonic origin, structure, physiological function, and biochemistry, apparently were established early in vertebrate evolution and are fully developed in chondrichthyan fishes. These features of the female reproductive system have been retained during the evolution of the other classes of vertebrates. Much the same can be said for the male reproductive system. Moreover, viviparity, placental nourishment of developing embryos, and the hormonal regulation of these events made an initial appearance in this group. The 22 articles presented in this volume bring together a wide variety of complementary research by investigators from seven countries, allowing us to broaden the scope and implications of our studies while identifying opportunities for future research. The appearance of a volume on the reproduction and development of cartilaginous fishes is quite opportune. The continued existence of these fishes, which survived the great extinction events of Earth's history, is now threatened by overexploitation unless immediate steps for their conservation are undertaken. Knowledge of their reproduction and development not only is an end in itself, but is of critical importance in devising successful conservation and resource management strategies.

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...
