As I understand it, the scars on sperm whales can be a bit misleading. Sperm whales feed on giant squid, and acquire sucker scars in the process when the squid resist. Very large sucker scars on adult sperm whales are thought to be acquired when the whales are younger and smaller, and to stretch as the whales grow.
