This book is the first stand-alone and definitive account of the cetaceans of the oceanic region from the equator to Antarctica, and between the longitudes of 20 Degrees W and 80 Degrees E - a region that includes almost two-thirds of the world's marine cetacean species. In the fascinating accounts of 51 species of whales and dolphins (and one porpoise), information for this region is comprehensively summarised, allowing Peter Best to give us the benefit of his extensive knowledge and of the wealth of unpublished information he has accumulated during his 40 years of studying these creatures. Approximately 100 illustrations have been created in colour for this book by world-renowned marine mammal illustrator Pieter Folkens. Colour photographs of the living animal portray the 'jizz' of each species and specific coloration or behavioural features.
