Veterinarian Brice Lefaux shares his passion and knowledge of a fascinating world with us. His observation of the daily lives of gibbons, Roloway monkeys, lemurs, and other Capuchins enables him to take us into their world. Alternating established scientific fact, never-before-seen data, and personal experience, he reveals their incredible diversity and ecological importance as well as threats to their existence and measures we can put in place to save them. A politically committed work enhanced by Jean Wollenschneide's striking, authentic illustrations.
