Hanna, familiar to many from his television appearances, provides an entertaining, informative, behind-the-scenes look at the Columbus Zoo. His anecdotal style and firsthand knowledge lend an extra thrill to such already exciting topics as how to move a venomous spitting cobra or raise a baby gorilla. Because this is an older title, some of the photos show zookeepers in outmoded fashions, but the many animal photos will never go out of style. Our favorites: Hanna rubbing oil into Clyde the rhinoceros’s skin and the gorilla getting a dental checkup.
