"...outclasses several other competing works, which tend to showcase marine mammals as special cases instead of focusing on the comparative and historical methods that demonstrate how they evolved…a necessary book for both beginners and experts. Students will find it readable, authoritative, and appealing with its extensive imagery." --The Quarterly Review of Biology

"I highly recommend this book for veterinary students or veterinarians at the start of their careers in marine mammal medicine or research who are looking for a supplemental reference on marine mammal biology." --Journal of the American Veterinary Medical Association

 "We should thank the authors for the great effort they have made to gather all the diverse information available and to present it in a highly comprehensive book, and one that can only be recommended to all readers interested in this challenging field." --M. S. Fischer, Jena, JOURNAL OF ZOOLOGICAL SYSTEMATICS AND EVOLUTIONARY RESEARCH

"...deals with the evolution of marine mammals in detail, and the remainder of the book is a good, solid guide to their complex biology. That said, Marine mammals: evolutionary biology will certainly be popular with students, because it is clearly and concisely written, and intelligently illustrated." --CAMBRIDGE UNIVERSITY PRESS

"...the book does represent a good reference source that I will certainly use myself, and it will serve those who teach these themes extremely well. Berta et al. deserve to be congratulated for this comprehensive tome - it is a thorough, precise and clearly written reference that will serve admirably those interested in the evolution of marine mammals." --Corey J.A. Bradshaw, School for Environmental Research, Charles Darwin University, POLAR RESEARCH
