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.

Unlike humans, who came down from the trees and developed bipedal locomotion, chimpanzees have remained in the original habitat of our ancestors: the tropical rainforests of Africa.
