PREFACE
The second edition, like the previous one, Marine Mammals: Evolutionary Biology, is
written for two audiences: as a text for an upper-level undergraduate or graduate-level
course on marine mammal biology and as a source book for marine mammal scientists
in research, education, management, and legal/policy development positions. One of
our major goals is to introduce the reader to the tremendous breadth of topics -
prise the rapidly expanding interdisciplinary field of marine mammal science
motivation for writing this book was the lack of prehensive text on marine mam-
mal biology, particularly one that employs parative, ic approach. We
have attempted,where possible,to demonstrate that hypotheses of the evolutionary rela-
tionships of marine mammals provide a powerful framework for tracing the evolution of
their morphology,behavior,and approach has much to offer but is limited,
in many cases, by parative data. We hope that this book stimulates others
to pursue marine mammal research in this exciting new direction.

ACKNOWLEDGMENTS
In preparing the second edition, we have been guided by the detailed, thoughtful, and
ments of colleagues and students. The many colleagues who con-
tributed photographs and line drawings are identified in the captions. We appreciate the
copyediting of Christian Lyderson and Fred Inge Prestenge for library assistance. The
production and editorial staff at Academic Press have been very helpful in preparation
of this book; we are especially grateful to our Developmental Editor, Kirsten Funk, and
Senior Editor, Andrew Richford, as well as the Manager of Editorial Services at SPI,
Christine Brandt. Finally, we thank friends and colleagues who provided inspiration by
asking, “Why do phylogenies matter?”Although we have relied on existing published lit-
erature for information, the in
