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.

For decades, Conservation International has devoted itself not only to saving endangered regions on the planet but also to chronicling, in lavish volumes, the biodiversity of these areas. These volumes, according to Choice, are"a superbly produced . . . source of hard-to-find information on biodiversity, biogreography, and conservation."
"Hotspots Revisited" continues this rich tradition, drawing on the organization's continuing work to identify, research, and document biologically diverse yet dangerously threatened regions. The first "Hotspots" volume identified twenty-five endangered regions; "Hotspots Revisited" reveals an astonishing nine additional areas, from Melanesia to northern Mexico, that now meet the same criteria.
"Hotspots Revisited "presents the most up-to-date analyses of the ecology of these endangered areas--including new information on freshwater fish and other animal populations. But the heart of the volume is in the hundreds of vibrant color photographs of the animals and plants under threat. Magnificent in conception and flawless in execution, "Hotspots Revisited" is equally at home on a scientist's shelf or an ecotourist's coffee table.
