Penguins, among the most delightful creatures in the world, are also among the most vulnerable. The fragile status of most penguin populations today mirrors the troubled condition of the southern oceans, as well as larger marine conservation problems: climate change, pollution, and fisheries mismanagement. This timely book presents the most current knowledge on each of the eighteen penguin species written by the leading experts in the field. The book also provides information on current conservation efforts, outlines the most important actions to be taken to increase each population's resilience, and recommends further research needed to protect penguins and the living creatures that share their environment.
