There’s a new fin whale subspecies in the North Pacific

  • The northern fin whale subspecies was previously believed to include populations in the North Atlantic and North Pacific oceans, but a recent genetic analysis of more than 150 fin whale samples from both ocean basins and the Southern Hemisphere showed that the two populations actually qualify as two separate subspecies.
  • By comparing DNA from fin whales in the North Pacific and the North Atlantic, researchers determined that the populations have been genetically distinct for hundreds of thousands of years.
  • Improving our understanding of fin whale taxonomy can have important implications for the conservation of the species, which is listed as Vulnerable on the IUCN Red List.
