The purpose of this book is to provide an introduction to comparative vertebrate anantomy for biology undergraduates. The information is presented in the form of colour photographs of step-by-step dissection stages intedgrated with a text on comparative anatomy. Dissection plays an important part in understanding the anantomy of an animal and this book has been designed to make full use of the wealth of information made available through dissection, and they represent examples of the six classes of vertebrates and in most cases they can be used as a guide to dissection of other vertebrates in the same class. Each of the six chapters deals with one animal and opens with information on the theoretical evolutionary history of the class to which it belongs. The comparative anatomy of the vertebrate brain is considered in the final chapter.
