The author uses the metaphor of a zoo to describe the various personalities and groups found in the typical organization. The characterizations are most apt, like hyenas who conspire together to bring down larger animals, to whales, whose strengths often become their weaknesses. The author (a biologist turned organizational change coach), also shows how you can use the habit of identifying which kind of creature a colleague or competitor most resembles to your advantage, by identifying their most conspicuous qualities, as well as hidden ones. He shows how to use the zoo analogy to lighten meetings, identify opportunities, and generally make the workplace experience lighter and more illuminating. If nothing else, you will laugh as you identify the animal habits of your most annoying colleagues!
