Figure 3: Migrating whales and other cetaceans appear able to follow magnetic lineations in the seafloor, which are aligned predominantly north-south. Other lineations oriented primarily east-west intersect these north-south lines; these east-west lines correspond to frature zones across the spreading ridges. The scale's colors and numbers denote how old the seafloor is in millions of years.
