Howard Rosenbaum

It's no fluke that Howard Rosenbaum is wild about whales—especially the endangered right whales and humpback whales. He's a conservation biologist specializing in genetics who deeply cares about the future of these marvelous mammals. Howard often travels to Madagascar to study humpbacks. By using observation, photography, and DNA analysis, he learns how these whales are related.
