The 17 species and subspecies of tree-kangaroos – inhabiting the rainforests of eastern Indonesia, Papua New Guinea and north-eastern Australia – are among the most spectacular of all mammals. The excellent illustrations and the comprehensive text reveal all aspects of the lives of these animals, their long fossil record, including the now-extinct giant species, their importance to indigenous peoples, their discovery by European naturalists, and ongoing studies to ensure their survival. Beautifully presented, this is an valuable addition to the mammalian literature.
