[The DNA extracted from these bits of whale skin not only identifies the individuals in the group, but also reveals their relationships to each other.]
 
Sperm whales travel in social groups that cooperate to defend and protect each other, and may even share suckling of calves. ( ¨ç ) It is difficult to determine the membership of these groups from sightings alone, because of the practical difficulties of observing whale behavior, most of which happens underwater. ( ¨è ) To make things even more difficult, sperm whales can travel across entire oceans and can dive to a depth of a kilometer. ( ¨é ) Biologists who study whale behavior generally have to be content with hanging around in boats, waiting for their subjects to surface. ( ¨ê ) But when they do surface, in addition to taking photos which allow individual whales to be identified, biologists can zip over in worryingly small boats and pick up the bits of skin that the whales leave behind on the surface when they re-submerge. ( ¨ë ) This has allowed researchers to describe sperm whale social groups in detail.
