About The Species

The blue whale is the largest animal ever known to have lived on Earth. They were significantly depleted by commercial whaling activities worldwide in the 1900’s and their population has struggled to recover. They are listed as endangered under the Endangered Species Act and depleted under the Marine Mammal Protection Act.

NOAA Fisheries is committed to conserving and protecting the blue whale. Our scientists and partners use a variety of innovative techniques to study, learn more about, and protect this species.
