Marine mammals include some of the most fascinating animals on Earth. Large, majestic whales and stunning, playful dolphins have provided mysterious companionship to humans at sea for hundreds of years. These magical creatures, along with the equally fascinating manatees, dugongs, seals, sea lions, and walrusses, have developed a completely different set of adaptations from their terrestrial ancestors and relatives. Volume 4 of the HMW series provides complete accounts of all species and families in these important groups. Lavishly illustrated with colour photographs showing different behaviours of all of them, the text contains the latest up-to-date information on all families of sea mammals.

The first work to illustrate and describe every living species of mammal on Earth. Volume 2 is devoted to Hoofed Mammals. The Handbook of the Mammals of the World (HMW) will be an unprecedented reference work for the Class Mammalia. This series of eight volumes will describe every currently recognized mammal species, along with an overview of each mammalian family. It will provide up-to-date information on the systematic relationships, natural history, ecology, and current conservation status for all mammals. Every species will be illustrated and each chapter will also include many color photographs. HMW will provide comprehensive worldwide coverage by involving an international group of expert authors.

Wilson and Reeder's Mammal Species of the World is the classic reference book on the taxonomic classification and distribution of the more than 5400 species of mammals that exist today. The third edition includes detailed information on nomenclature and, for the first time, common names. Each concise entry covers type locality, distribution, synonyms, and major reference sources. The systematic arrangement of information indicates evolutionary relationships at both the ordinal and the family level. This indispensable reference work belongs in public and academic libraries throughout the world and on the shelf of every biologist who works with mammals.
