Global distribution of fin whales Balaenoptera physalusin the post‐whaling era (1980–2012)
Abstract The global distribution of fin whales B alaenoptera physalus is not fully understood. Existing maps can be divided into two conflicting categories: one showing a continuous global distribution and another showing an equatorial hiatus (gap in the global distribution) between approximately 20...

However, our synthesis and results from other studies also indicate that some fin whales in both hemispheres remain in higher latitudes (50°–60° north or south) during colder months and in lower latitudes (to approximately 20°–30° north or south) during warmer months, indicating that seasonal fin whale movements differ from the seasonal migrations of blue whales B alaenoptera musculus and humpback whales M egaptera novaeangliae .
