Shortlisted for THE WAINWRIGHT PRIZE 2017‘The best popular account of the lives of otters written so far’ Richard Shelton, Times Literary Supplement

In 1419, the Emperor of China sent the most magnificent fleet of ships ever seen around the world. Besides sailors, ambassadors and such on board, there were the inevitable rats, faithful dogs and a certain group of fishing otters. The old Emperor died whereupon his jealous son, the new Emperor, ordered his fathers ships, upon return, to be destroyed, as well as the animals on board. One ship crashed before returning on the shores of Ruapuke Beach, New Zealand. Until now, no one has known the cause. The animals knew. This is their story.

Otters are highly charismatic and popular animals of very considerable concern to conservationists worldwide. Written by the pre-eminent authority in the field, this book builds on the reputation of the author's landmark monograph of the European otter, Wild Otters (OUP, 1995). Furthermore, its broader scope to include all species of otter in North America as well as Europe and elsewhere leads to a deeper synthesis that greatly expands the book's overall relevance and potential readership. Aimed at naturalists, scientists and conservationists, its personal style and generously illustrated text will appeal to amateurs and professionals alike. It emphasises recent research and conservation management initiatives for all 13 species of otter worldwide, incorporates recent molecular research on taxonomy and population genetics, and discusses the wider implications of otter studies for ecology and conservation biology. As well as enchanting direct observations of the animals, there is guidance about how and where to watch and study them. From otters in the British and American lakes and rivers, to sea otters in the Pacific Ocean, giant otters in the Amazon and other species in Africa and Asia, this book provides an engaging approach to their fascinating existence, to the science needed to understand it, and to the very real threats to their survival.
