Blue Whale Range Distribution

Chart 2 -- Blue Whale Range Distribution.

Blue Whales are the largest animal to live on earth and in the past decade its numbers have surged locally. The Monterey Bay National Marine Sanctuary hosts several hundred blue whales annually who come to the region to feed on krill. These animals are highly mobile and it is thought that they move regularly between the Monterey Bay region and other feeding grounds near Cordell Bank and the Channel Islands. Blue Whales within the MBNMS range throughout the Sanctuary boundaries from May to December as depicted by the blue dots. The area in green illustrates the major adult area from May to September.
