Australians are lucky to live alongside more than half of the world's marine mammal species.

This practical Wild Australia Guide "takes the reader underwater" — with colour photos and authoritative text — to identify each species and reveal the complex societies of these beautiful mammals that are so perfectly adapted to life in a buoyant, underwater world.

With details of land-based vantage points as well as the increasing number of expedition boats to the bays, islands and offshore waters where these animals live, this book gives everyone the chance to explore the lives of these acrobatic, majestic and mysterious creatures.
