Having worked for over 20 years on otter conservation of all 13 species, the authors wished to share their experiences of these beautiful animals. People may be familiar with the Asian small-clawed otters, often found in zoos, or the sea otter, well-known for lying on its back cracking open shells, but may not be aware that there are more fascinating species. It is hoped the book will increase public support for the work of the IOSF (International Otter Survival Fund) and awareness of the terrible plight of otters which in many countries are on the verge of extinction. Each species is listed in the IUCN Red Data List and yet little attention is given to their predicament. The illegal wildlife trade in otters is huge - not just for furs and body parts but as pets. In some parts of the world otters are disappearing rapidly and unless urgent action is taken they will be gone forever.
