Sub-titled 'History and Biology of the Lords of the Sea', this book explains how these top marine predators have evolved as they have, and how and why they do what they do. This study of these highly developed and diversified creatures provides an account of their evolution and compares their various fossil forms with those of the fish that preceded them. It looks at the anatomy of sharks and their reproduction, what they eat, how they swim and breathe, and what makes them attack man. It includes an overview of the various families and species still in existence with superb colour pictures and helpful colour illustrations. The latter cover everything from anatomical cut-aways to fin and teeth designs, but among the most interesting are full-page depictions of typical habitats accompanied by a key showing how different shark species coexist with other marine creatures and with one another. A truly authoritative guide to a subject guaranteed to fascinate divers and non-divers alike.
