Hal Whitehead shares the picture of the social structures, and most recently, the cultures that he has built from studying sperm whales for more than 20 years, tracking their movements from his sailboat, identifying individual whales from photographs, recording sounds, and collecting their dandruff (for genetic analyses) and feces (for diet analysis).
Although Hal Whitehead is normally based in the Department of Biology, Dalhousie University, Halifax, Nova Scotia, Canada, he likes best to be at sea.
